ABSTRACT Injecting discontinuities is a recurrent procedure for the rehabilitation of concrete hydraulic structures, namely repairing cracked dam bodies and deteriorated lift and contraction joints. Within this scope, a relatively detailed description of the most important cement injection grouts features is presented, including the main advantages and drawbacks compared to alternatives. The cement-based grouts are among the most utilised materials in these contexts. Economic and environmental related aspects are among the main advantages of cement-based grouts, although some technical features of these grouting materials are also favourable. The equipment utilised for the preparation and for the application of cementitious grouts is also mentioned. This document also addresses aspects related to the assessment of concrete dams’ stability, the preparatory works, the common methodologies and the standard precautions to have into account when planning a rehabilitation operation involving cement grouting for filling cracks or repairing lift or contraction joints in these massive structures. A list of successful rehabilitation case histories is provided, including a short description of the anomalies and their causes, as well as a summary of the main repair measures adopted for each situation.

ABSTRACT As the demand for field testing of bridges grows, so does the need to optimize field testing procedures to allow for a simplified testing strategy that can be employed more effectively. With the advent of computer vision, there has been limited research exploring Feature-Based Image Registration (FBIR) methods for structural testing of bridges. In this paper, the potential of a simple FBIR approach to accurately capture submillimeter displacements using consumer-grade cameras will be demonstrated through a field test on a reinforced concrete slab bridge and on a full-scale bridge deck specimen in the laboratory. The internal and external parameters that influence the results of this measurement strategy were investigated by using various camera positions during the laboratory tests and applying different threshold parameters to the Speeded-Up Robust Features algorithm used for the feature detection and matching. The FBIR method demonstrates great potential, producing an average measurement accuracy within 1.6% of conventional displacement sensors during the field test and 3.3% during the laboratory tests. Altogether, the advantages to this image-based measurement approach enhance the load testing strategy to be implemented by bridge owners at much lower costs and with minimal complication and field setup.
随着桥梁现场测试需求的增长,优化现场测试程序的需求也在增长,以简化测试策略,从而更有效地应用。随着计算机视觉的出现,基于特征的图像配准(FBIR)方法在桥梁结构检测中的应用研究有限。在本文中,将通过在实验室的钢筋混凝土板桥和全尺寸桥面样品上进行现场测试,展示使用消费级相机精确捕获亚毫米位移的简单FBIR方法的潜力。通过在实验室测试中使用不同的相机位置,并对用于特征检测和匹配的加速鲁棒特征算法应用不同的阈值参数,研究了影响该测量策略结果的内部和外部参数。FBIR方法显示了巨大的潜力,在现场测试中,其平均测量精度在常规位移传感器的1.6%以内,在实验室测试中为3.3%。总之,这种基于图像的测量方法的优势增强了桥梁业主以更低的成本和最小的复杂性和现场设置来实施负载测试策略。

ABSTRACT In recent years, strengthening methods for reinforced concrete structures using fibre-reinforced polymer (FRP) composites have been gaining widespread interest and growing acceptance in civil engineering industry. Near surface mounted (NSM) reinforcement as well as externally bonded reinforcement (EBR) sheets have emerged as new strengthening methods in which external reinforcement (in the form of bars or sheets) is embedded into grooves or adhered to the section with epoxy adhesive. This paper proposes a simplified analytical approach to predict flexural behaviour of simply supported reinforced-concrete (RC) beams strengthened with carbon fibre-reinforced polymer (CFRP) using the above-mentioned methods. The flexural capacity and deformational behaviour of FRP strengthened beams are analysed using trilinear moment curvature relationship at three critical points namely (i) crack initiation point (ii) steel yield initiation point and (iii) ultimate capacity point, based on strain compatibility and principles of equilibrium. A good predictive performance of analytical model is appraised by simulating force-deflection response registered in the experimental program composed of RC beams strengthened with NSM as well as EBR methods. The analytical solutions have also given accurate prediction of experimental results in the literature regardless of the arrangement of CFRP reinforcement.
摘要近年来,使用纤维增强聚合物(FRP)复合材料加固钢筋混凝土结构的方法在土木工程行业受到了广泛的关注和认可。近表面安装(NSM)钢筋和外部粘结钢筋(EBR)板已成为新的加固方法,其中外部钢筋(以钢筋或板的形式)嵌入凹槽或用环氧粘合剂粘附在截面上。本文提出了一种简化的分析方法来预测碳纤维增强聚合物(CFRP)加固的钢筋混凝土(RC)梁的弯曲性能。基于应变相容性和平衡原理,利用三线弯矩-曲率关系分析了FRP加固梁在三个临界点(i)裂纹萌生点(ii)钢屈服萌生点和极限承载力点)的抗弯承载力和变形性能。通过模拟NSM和EBR方法加固RC梁的试验程序中记录的力-挠度响应,评价了分析模型的良好预测性能。无论CFRP加固的布置如何,分析解也对文献中的实验结果给出了准确的预测。

ABSTRACT Bridge health monitoring has been attempted to ensure the safety of the bridges in their operations, employing various measurement options like acceleration, strain, displacement, etc. The relative efficacy of these measurements as a damage-sensitive response has remained a topic of research. While acceleration has traditionally been used in abundance, dynamic strain, being relatively cheaper to record, also holds the potential to replace acceleration. This study undertakes a comparative investigation weighing the relative benefits of both the measurement options for prompt and reliable damage detection in both the time and frequency domain. The comparison is drawn in the light of damage sensitivity, intensity and consistency of the damage signature of the adopted measurement type while keeping the damage and loading specifications unaltered. A multi-span concrete box girder has been replicated with a high-fidelity numerical model as a proxy for the real structure followed by an experimental validation on a propped cantilever beam. Acceleration and strain responses are measured and analyzed for different damage conditions. A rigorous sensitivity analysis is undertaken to compare explicitly the performance of both the measurement options. The results demonstrated superior performance with the strain response in time and frequency domains from consistency and intensity perspectives.
摘要:桥梁健康监测一直试图确保桥梁在其运行中的安全,采用各种测量选项,如加速度,应变,位移等。这些测量作为损伤敏感反应的相对功效仍然是一个研究课题。虽然加速度在传统上被大量使用,动态应变,相对便宜的记录,也有可能取代加速度。本研究进行了一项比较调查,权衡了两种测量方法在时域和频域的相对优势,以实现快速可靠的损伤检测。在保持损伤和加载规格不变的情况下,根据所采用的测量类型的损伤灵敏度、强度和损伤特征的一致性进行比较。用高保真数值模型模拟了多跨混凝土箱梁的实际结构,并在悬臂梁上进行了试验验证。测量和分析了不同损伤条件下的加速度和应变响应。进行了严格的敏感性分析,以明确比较两种测量方案的性能。结果表明,从一致性和强度的角度看,该方法在时域和频域上具有较好的应变响应性能。

ABSTRACT There are several ongoing humanitarian crises all around the world that have led to many refugees, who need affordable shelters and saferooms. Additionally, these structures are widely located in the backyard of homes in case of hurricanes, tornados, and/or earthquakes. This paper presents a chronological literature review of investigations and comparisons on characteristics of different type of saferoom/shelter wall systems. The characteristics, scrutinized in this study for each type of wall, include structural strength, construction cost, time to construct, and sustainability of saferoom/shelter walls. The most significant contributions of these studies are identified and presented. The results showed that soilbag shelter walls can be constructed with relatively low cost, relatively shorter time, and being relatively more sustainable compared to other types of shelter walls considered in this study. Soil-filled earthbag specimens are stronger and stiffer than gravel-filled specimens of identical size and stack geometry. Using locally available materials minimizes the energy needed and pollution produced due to material transportations. Furthermore, recyclable waste bags can be used to produce bags in soilbags. A slanted roof can be used in any type of shelter wall to harvest rainwater for each shelter use. Moreover, the literature review indicated that the shelter walls made of CLT, and lumber panels are generally stronger against wind loads (250-mph) compared to walls made of soilbags (225-mph).
摘要世界各地正在发生的几场人道主义危机导致许多难民需要负担得起的住所和安全室。此外,这些建筑广泛位于家庭后院,以防飓风、龙卷风和/或地震。本文对不同类型的安全室/遮蔽墙系统的特征进行了调查和比较,并按时间顺序进行了文献综述。在本研究中,对每种类型的墙进行了仔细研究,包括结构强度、施工成本、施工时间以及安全室/遮蔽墙的可持续性。确定并介绍了这些研究中最重要的贡献。结果表明,与本研究中考虑的其他类型的遮蔽墙相比,土袋遮蔽墙可以以相对较低的成本、相对较短的时间建造,并且相对更具可持续性。填土土袋试样比相同尺寸和堆叠几何形状的砾石土袋试样更坚固、更坚硬。使用当地可用的材料可以最大限度地减少材料运输所需的能源和产生的污染。此外,可回收的垃圾袋可用于制作土壤袋中的袋子。倾斜的屋顶可以用于任何类型的遮蔽墙,为每个遮蔽墙收集雨水。此外,文献综述表明,与土袋墙(225英里/小时)相比,由CLT和木板制成的遮蔽墙通常更能抵御风荷载(250英里/小时的风荷载)。

ABSTRACT The Ten Arches Bridge is a historical stone bridge that is located in Amman, Jordan. The bridge has a valuable cultural heritage as it was built in 1908 to serve the Hejaz Railway Line. This study presents a structural assessment of the bridge including a field inspection, experimental investigation, and numerical structural analysis. The study also investigates the efficacy of utilizing in-situ Non-Destructive Testing (NDT) such as Rebound Hammer (RH) and Ultrasonic Pulse Velocity (UPV) tests in the assessment of stone arch bridges. Detailed experimental and numerical investigations were performed to identify the structural integrity of the bridge by evaluating the acting stresses and displacements under static and dynamic loads. Minor deteriorations were found in the bridge’s body due to human and environmental factors. However, the geometrical properties of the bridge have not been significantly changed. The obtained results of the numerical analysis concluded that the bridge can sustain the current imposed dead and traffic loads, but not serve seismic actions. Compressive strength and modulus of elasticity of stone units obtained by RH and UPV tests are in agreement with the laboratory tests. Accordingly, NDT techniques can provide and verify basic mechanical properties that are needed for numerical analyses.
摘要十拱门大桥是一座历史悠久的石桥,位于约旦安曼。这座桥建于1908年,为赫贾兹铁路线服务,因此拥有宝贵的文化遗产。本研究对该桥进行了结构评估,包括现场检查、试验研究和数值结构分析。该研究还调查了利用原位无损检测(NDT)(如回弹锤(RH)和超声波脉冲速度(UPV)测试)评估石拱桥的效果。通过评估静态和动态载荷下的作用应力和位移,进行了详细的实验和数值研究,以确定桥梁的结构完整性。由于人为因素和环境因素,桥体出现轻微损坏。然而,该桥的几何特性并未发生显著变化。数值分析结果表明,该桥能够承受当前施加的恒载和交通荷载,但不能承受地震作用。通过RH和UPV测试获得的石材单元的抗压强度和弹性模量与实验室测试一致。因此,无损检测技术可以提供和验证数值分析所需的基本机械性能。

ABSTRACT This research proposes a new approach, in which a tuned mass damper (TMD) is installed in an articulated tower subjected to moving loads caused by ground. Then, the vibration equations of the system are formulated for analyzing and selecting the optimal parameters of the tuned mass damper to reduce the harmful vibrations. The maximization of equivalent viscous resistance method is applied to determine the optimum parameters of the tuned mass damper. The purpose of designing the tuned mass damper is to suppress the vibrations of the articulated tower. The results show that the vibration of the articulated tower is effectively eliminated by using the optimum parameters of the tuned mass damper in this paper. In particular, the optimum expressions are given in analytical solutions, which involve the parameters in well-understood forms to derive the exact solution of the optimum parameter. These optimum expressions, helping the researchers easily design the tuned mass damper on controlling vibrations of the articulated tower.

Probabilistic deterioration modeling of bridge component condition with random effects 随机影响下桥梁构件状态的概率劣化建模

ABSTRACT Timely maintenance of bridge components is critical for bridge management functions. With reliable deterioration models, highway agencies can efficiently allocate funding for bridge maintenance and customize maintenance schedules to meet agency budgets. The increased public expectation of acceptable levels of service for bridges coupled with other competing needs makes it crucially important to accurately estimate bridge future conditions so that adequate resources may be allocated for repair and reconstruction purposes. Accurately predicting bridge condition is challenging due to the inherent random nature of factors impacting deterioration, the existence of unobserved variables that are not measured, panel nature of the data and the effects of bridge-specific correlation. Without accounting for these factors, the resulting estimated deterioration models may have biased and inconsistent parameter estimates. This article assembled a comprehensive set of bridge and climate data from the National Bridge Inventory (NBI) and the South Carolina Climatology office. Bridge component deterioration models for bridges on state highways in South Carolina were estimated using an ordered probit model with random effects specification to account for the randomness and panel nature of the bridge data. The study results are useful for various bridge management tasks including maintenance programming, budgeting and bridge asset evaluation.
及时维护桥梁构件对桥梁管理功能至关重要。有了可靠的老化模型,公路机构可以有效地分配桥梁维修资金,并定制维修计划以满足机构预算。公众对桥梁可接受的服务水平的期望越来越高,再加上其他相互竞争的需求,这使得准确估计桥梁未来的状况变得至关重要,以便为修复和重建目的分配足够的资源。由于影响恶化的因素具有固有的随机性,存在未测量的未观察变量,数据的面板性质以及桥梁特定相关性的影响,因此准确预测桥梁状况具有挑战性。如果不考虑这些因素,估计的退化模型可能有偏差和不一致的参数估计。本文收集了一套全面的桥梁和气候数据,这些数据来自国家桥梁清单(NBI)和南卡罗来纳州气候学办公室。为了考虑桥梁数据的随机性和面板性质,使用随机效应规范的有序probit模型估计了南卡罗来纳州州际公路桥梁部件退化模型。研究结果可用于各种桥梁管理工作,包括维修规划、预算编制和桥梁资产评估。

ABSTRACT This paper presents an experimental study of the structural behaviour of masonry walls strengthened with steel-welded wire mesh (WWM) overlay with mortar to improve their in-plane shear strength and deformation capacity. The experimental programme consists a compression testing of masonry prism and a diagonal compression testing of 15 wall specimens made of clay brick strengthened with four different WWM systems: (i) embedding WWM along the bed joint, (ii) embedding WWM along the bed joint and a strip diagonally crossing on wall surface, (iii) WWM alternately embedding along the bed joint and continue to the surface of wall and (iv) WWM fully cover on wall surface. The experimental results show that the adopted WWM-strengthening solutions produce a beneficial increase of compressive strength, shear resistance, ductility and energy dissipation capacity making them suitable for seismic strengthening.

ABSTRACT Many studies have only studied carbonation and chloride penetration separately, and study dealt with synergy interaction between these is very rare. This study is devoted to examining the chloride penetration parameters of carbonated cementitious materials, i.e. (a) surface chloride content, (b) chloride diffusivity, (c) chloride adsorption capacity and (d) critical chloride content linked with reinforcement corrosion directly. These chloride transportation parameters were expressed as a function of time in each condition because these depend on the mixing proportional properties and the degree of cement hydration. This study is expected to be useful to develop a chloride penetration model of carbonated concrete in the future.
许多研究只分别研究了碳酸化和氯离子渗透,而研究这两者之间的协同作用的研究非常罕见。本研究致力于检验碳化胶凝材料的氯离子渗透参数,即(a)表面氯离子含量,(b)氯离子扩散率,(c)氯离子吸附能力和(d)与钢筋腐蚀直接相关的临界氯离子含量。这些氯化物输送参数在每种条件下都表示为时间的函数,因为这些参数取决于混合比例特性和水泥水化程度。这项研究有望对未来开发碳酸混凝土的氯离子渗透模型有所帮助。
