This study focuses on the flexural behavior of a composite construction consisting of three concrete filled steel tubular (CFST) chords connected by a circular steel braces. The CFST members exhibit advantages such as stiffness, strength, capacity, and ductility compared to conventional steel and reinforced concrete members. The study uses CATIA V5 software for modelling the truss specimens, and ANSYS software for finite element analysis. The main parameters examined include shear span ratio, angle between brace and chord, presence of infilled concrete, subsequent flexural behavior, and material interaction. The moment of resistance of the CFST truss with braces is calculated using the working stress method, and a design table for ultimate load carrying capacity of different circular sections is generated. The study aims to understand the effects of shear span ratio, angle of chord, brace, and presence of infill concrete on the CFST chord and brace girder.

The paradigm for structuring street vendors is not to eliminate the existence of small businesses which are a real form of people's economy. Paradigm change as a burden is transformed into an asset. In its implementation, it does not follow the guidelines for structuring and empowering street vendors. This research aims to examine and analyze the factors of facilitative leadership in the contingency model of collaborative governance by elaborating on collaborative governance that brings together and directs stakeholders and the private sector in structuring street vendors (PKL). The research method used is a descriptive qualitative approach with case study methods and data collection techniques using literature studies, interviews, observations, FGDs, and triangulation. The research results found that the need for an "Executor" Leader according to experts is that collaborative abilities are very important for Execution. Facilitative Leadership has a very important role in the Initial Conditions dimension. The new findings in this research place elements of the leader's background together with power asymmetries and a history of cooperation/conflict as a basis that can hinder or support the collaborative process that is built. Facilitative leadership has a very important role in the institutional design dimension.
构建街头小贩的模式并不是要消除小企业的存在,小企业是人们经济的一种真实形式。作为负担的范式变化被转化为资产。在实施过程中,它没有遵循组织和授权街头摊贩的指导方针。本研究旨在通过阐述协作治理将利益相关者和私营部门聚集在一起并指导他们构建街头小贩(PKL),来检验和分析协作治理权变模型中促进型领导的因素。使用的研究方法是描述性定性方法,结合案例研究方法和数据收集技术,使用文献研究、访谈、观察、fgd和三角测量。研究结果发现,根据专家的说法,对“执行者”领导者的需求是协作能力对执行非常重要。促进型领导在初始条件维度中具有非常重要的作用。这项研究的新发现将领导者的背景因素与权力不对称以及合作/冲突的历史作为阻碍或支持建立的合作过程的基础。促进型领导在制度设计维度中具有非常重要的作用。

The intricacies inherent in comprehending stress distribution within the proximity of the termination section of a post-tensioned member, specifically the anchorage zone, underscore the need for precise and viable assessment methods for regions susceptible to heightened stress levels. This study presents a meticulous approach for evaluating anchorage zone stresses, particularly bursting and spalling stresses, utilizing three-dimensional stress distribution using FE analysis employing the ABAQUS program. The effectiveness of the finite element model was verified through a mesh sensitivity analysis. In the evaluation of anchorage zone stresses, multiple anchorage zone reinforcement configurations were meticulously modeled, encompassing distribution ratios (the ratio of the depth of the anchor plate to that of the anchorage zone) spanning from 0.2 to 0.9. This comprehensive analysis facilitated the examination of stress variations, specifically bursting and spalling stresses, across the span of the anchorage zone. Various attempts were made to mitigate these stresses, employing innovative reinforcement configurations, which were systematically compared with conventional counterparts. The outcomes of this study distinctly illustrate that regions experiencing excessive stress levels are efficiently managed with the implementation of suitable reinforcement configurations. The results demonstrate that both bursting and spalling stresses can be effectively controlled in post-tensioned specimens' anchorage zones, achieving reductions of 62% and 33%, respectively, through the strategic deployment of proposed advanced reinforcement configurations.
理解后张构件终止段附近的应力分布固有的复杂性,特别是锚固区,强调需要对易受高应力水平影响的区域进行精确和可行的评估方法。本研究提出了一种精细的方法来评估锚固区应力,特别是破裂和剥落应力,利用三维应力分布,利用ABAQUS程序进行有限元分析。通过网格灵敏度分析验证了有限元模型的有效性。在锚固区应力评估中,精心模拟了多个锚固区加固配置,包括0.2至0.9的分布比(锚板深度与锚固区深度之比)。这种综合分析有助于检查应力变化,特别是破裂和剥落应力,跨越锚固区跨度。为了减轻这些压力,研究人员进行了各种尝试,采用了创新的加固配置,并与传统的加固配置进行了系统的比较。本研究的结果清楚地表明,通过实施适当的加固配置,可以有效地管理承受过度应力水平的区域。研究结果表明,通过优化加固配置,可有效控制后张试件锚固区破裂应力和剥落应力,分别降低62%和33%。

This study presents an experimental investigation aimed at enhancing soil stability through the synergistic application of bagasse ash in conjunction with Guar gum (GG) and Xanthan gum (XG) biopolymers. Soil stabilization is a critical aspect of construction and land management, especially in regions where red soil predominates. Due to its pozzolanic qualities, the by-product of sugarcane processing known as bagasse ash has demonstrated potential as a soil stabilizer. Guar gum (GG) and Xanthan gum (XG), natural biopolymers, have demonstrated promise in improving soil engineering characteristics. This research contributes to the evolving field of sustainable soil stabilization techniques, offering insights into the potential of bagasse ash and biopolymers in mitigating soil-related challenges. In the current study, Xanthum gum (XG) and Guar gum (GG) in varied percentages was employed in experimental experiments on red soil as a material for soil improvement. In this investigation, soil was also replaced with Bagasse ash up to 10% of its volume and its strength attributes were assessed. It was found through studies utilizing different Biopolymers concentrations (XG & GG) the soil's strength was improved.

The analysis of the behavioral change of temperature on rigid pavement is a critical aspect of understanding the performance and durability of concrete roadways. Temperature fluctuations significantly impact the rigid pavement, leading to distresses such as cracking, deformation, and reduced service life. This experimental study aims to investigate the effects of temperature variations on the behavior of rigid pavement and develop strategies to mitigate potential issues. The objective of this research is to analyze the behavioral response of rigid pavement under controlled temperature changes. To achieve this objective, a representative section of rigid pavement was selected for testing. The pavement sample was constructed according to standard specifications, ensuring it accurately represents real-world conditions. The sample consisted of typical layers found in a rigid pavement structure, including the concrete slab, base, and sub base layers. The collected data was analyzed to understand the effects of temperature changes on the rigid pavement. Statistical analysis and visualization techniques were employed to identify patterns, trends, and correlations between temperature variations and the observed behavioral changes. The analysis provided insights into the susceptibility of rigid pavements to temperature-induced distress, such as thermal cracking and differential expansion.

The structure of a chemical compound is usually modelled as a graph, which is so-called a molecular graph. It has been found that some topological indices of a molecular graph      are closely related to many physicochemical properties of its chemical compounds. From  this relation, it arises the important inverse topological indices problem, that carry out a  thorough search of the existence of a graph having its index value equal to a given integer. In this paper, we are interested in solving this problem for the first, second and third leap Zagreb indices of connected graphs. We are also restricting the solutions to trees and unicyclic graphs. It is shown that for every even non-negative integer k there exists a graph having its first leap Zagreb index value equal to k. For every non-negative integer k, except 2, there exists a graph having its second leap Zagreb index value equal to k and for every non-negative integer k, except 1, 3, 5, 7, 9, 11, 17, there exists a graph having its third leap Zagreb index value equal to k. The general formulas of leap Zagreb indices values for some certain trees   and unicyclic graphs which are useful in this work are presented.  
化合物的结构通常用图来表示,即所谓的分子图。研究发现,分子图的一些拓扑指标与其化合物的许多物理化学性质密切相关。从这一关系中,产生了重要的逆拓扑指标问题,它对索引值等于给定整数的图的存在性进行了彻底的搜索。本文研究了连通图的一、二、三跃萨格勒布指数的这一问题。我们也将解限制为树和单环图。证明了对于每一个偶非负整数k存在一个图,其第一次跳跃的萨格勒布索引值等于k,对于每一个非负整数k,除了2,存在一个图,其第二次跳跃的萨格勒布索引值等于k,对于每一个非负整数k,除了1,3,5,7,9,11,17,存在第三跳萨格勒布指标值等于k的图。给出了某些树和单环图的跳萨格勒布指标值的一般公式,这对本文的工作是有用的。

A Review: On Self Compacting Concrete 回顾:自密实混凝土
Q3 Engineering Pub Date : 2023-12-03 DOI: 10.52783/tjjpt.v44.i5.2731
O. Ankamma Raju, Dr. T. V. S. Vara Lakshmi
This study unveils an overview of self-compacting concrete (SCC) and how it may be churn out using a variety of mineral Admixtures and fibers. The Desire for enormous and intricate constructions in the present construction industry situation often leads to extreme concreting conditions. It can be tricky to ensure that an enormous quantity of heavy reinforcement in a reinforced concrete (RC) section is properly compacted without voids or honeycombs. Compaction by hand or mechanical vibrators is difficult in this situation. As a result, a new form of concrete dubbed self-compacting concrete (SCC) is designed. This concrete swiftly flows around the reinforcement and traverse the formwork's extremities. Self-compacting concrete is a form of concrete that can compact itself using only its own weight and no vibration. Self-compacting concrete is a type special concrete. This review studies demonstrates how fibers and other mineral admixtures are incorporated into SCC characteristics.  
本研究揭示了自密实混凝土(SCC)的概述,以及如何使用各种矿物外加剂和纤维来生产自密实混凝土。在当前的建筑行业形势下,对庞大而复杂的建筑的渴望往往导致极端的混凝土条件。要确保在钢筋混凝土(RC)部分中大量的重钢筋得到适当的压实,而没有空隙或蜂窝,这可能是一件棘手的事情。在这种情况下,用手或机械振动器压实是困难的。因此,设计了一种新的混凝土形式,称为自密实混凝土(SCC)。混凝土在钢筋周围迅速流动,并穿过模板的末端。自密实混凝土是混凝土的一种形式,它可以只使用自身的重量而不振动。自密实混凝土是一种特种混凝土。本文综述了纤维和其他矿物外加剂是如何被纳入SCC特性的。
