—Viscous Dampers (VDs) are widely used as passive energy dissipation system for improving seismic performance levels especially in retrofitting of buildings. Residual Inter-story Drift Ratio (R-IDR) is another important factor that specifies the condition of building after earthquake. The values of R-IDR illustrates the possibility of retrofitting and repairing of a building. Therefore, this study aims to explore the vector-valued Intensity Measures (IMs) for predicting the R-IDR of two group of steel Moment-Resisting Frames (MRFs) with and without implementing VDs. Incremental Dynamic Analysis (IDA) was performed with considering RIDR using OpenSees software. Efficiency and sufficiency have been quantified for 18 vector-valued IMs with respect to the Residual Interstory Drift Ratio (R-IDR). Results showed that two vector-valued IMs of (Sa(T 1 ), SaRatio M-D ) and (Sa(T 1 ), I M-D ) had lower σlnSa RD |IM 2 values in the R-IDR of 0.002, 0.005, 0.01, and 0.02, and they had higher FR in the mean dispersion, (σlnSaRD|IM2)avg, compared to other IMs. In addition, two vector-valued IMs of (Sa(T 1 ), SaRatio M-D ) and (Sa(T 1 ), I M-D ) achieved p-values higher than 0.05 with respect to seismic ground motion features of M, R, and Vs30, and can be used as optimal vector-valued IMs.
粘性阻尼器(VDs)作为一种被动耗能系统被广泛应用于提高建筑物抗震性能水平，特别是在建筑物的改造中。剩余层间位移比(R-IDR)是反映建筑物震后状态的另一个重要因素。R-IDR的价值说明了对建筑物进行改造和修理的可能性。因此，本研究旨在探索矢量值强度测量(IMs)来预测两组钢抗弯矩框架(mrf)的R-IDR，这些框架有和没有实施VDs。使用OpenSees软件考虑RIDR进行增量动态分析(IDA)。根据剩余层间漂移比(R-IDR)，对18个矢量值IMs的效率和充分性进行了量化。结果表明，在R-IDR分别为0.002、0.005、0.01和0.02的情况下，(Sa(t1)， SaRatio M-D)和(Sa(t1)， I M-D)两种向量值IMs的σlnSaRD|IM2值较低，平均色散FR (σlnSaRD|IM2)平均值较其他IMs高。此外，(Sa(t1)， SaRatio M- d)和(Sa(t1)， IM - d)两个向量值IMs对M、R和Vs30的地震动特征的p值均大于0.05，可以作为最优向量值IMs。

This paper describes study on permeation of ultra-fine particle cement grout into sandy ground. The cement grouting method was one of the improvement methods to strengthen the sandy ground. However, the conventional cement grout was difficult to permeate into sandy ground. The purpose of this study is to clarify the permeation of the ultra-fine particle cement grout into dry and saturated sands. The author conducted both column and model ground injection tests to examine the permeability of ultra-fine particle cement grout. As a result, ultra-fine cement grout had high permeability against finer sand regardless of dry and/or saturated conditions and the stabilized area was wider.

Based on lean thinking which developed from the Toyota industry, seek to wastes elimination, increase the value added to the product from customer point of view and reduce lead time are the main contributes in manufacturing industrial environment. Some adaptations have been applied in construction industry by using a Value Stream Mapping as a lean construction tool. VSM was adapted to reduce the high percentage of non-value-added activities and time wastes during each construction stage. Moreover, a cost estimation model was developed during current state and future state to calculate the cost of underground pipeline construction. Therefore, this paper aims to propose improvements in the construction industry process using Value Stream Mapping. Therefore, the research methodology adopted was the illustrative case study. The results suggest that the construction of underground pipelines process lead time could be potentially reduced by 30.7 % and cost reduction of 20.8 % between current and future states.

Currently in Japan, a field survey by building experts is required to determine whether earthquakeafflicted buildings can continue to be used after an earthquake, so that official decisions on national and municipal-level assistance cannot be made without the completed survey results. Authors plan to introduce an automated real time seismic diagnostic system to the disaster prevention centers. This system consists of the seismometers installed in the building and observation data are saved in Internet clouds. Immediately after the earthquake, the system performs a simple diagnosis on the residual seismic performance of the building and notifies the results by e-mail. The MDOF lumped-mass model for use in the simple diagnosis is assumed to have normal tri-linear hysteretic characteristics at each story, using constants determined by referring to the analytical 3D frame model. This paper explains the proposed system and introduces the results of trial operation to the actual city hall buildings at the 2018 Osaka earthquake. After the Osaka Earthquake, the system was able to notify disaster prevention officials at the city hall of the results of the simple diagnosis within two minutes after the earthquake ended.

—With the application of boundary layer theory, the N-S equation in the boundary layer of the wall is simplified in this research. Combined with the boundary conditions, the relationship between the wall pressure gradient and the velocity gradient near the wall is obtained, therefore the roof pressure characteristics and the location of the separation point are analyzed. The rigid model of low-rise building with flat roof was fabricated. The combination of wind tunnel test and theory is utilized to analyze the distribution characteristics of roof pressure. The suction device is designed to complete the wind tunnel pressure test of the low-rise building model under active suction. The influence of the suction position on the roof wind pressure is studied, and the mechanism of the suction-to-wall turbulence control is proposed. Research results show that the arrangement of the suction device in the separation bubble area has a significant influence on the average wind pressure coefficient of the roof, which can greatly reduce the suction of the roof.

— In this study, the axial force loss of high-strength bolt after 3kW CW-laser treatment was examined. High-strength bolt specimens were prepared, and a hand-held laser transmitter was irradiated on the bolt head with CW-laser power of 3kW. The change in the axial force on the bolts was examined during the bolt's treatment based on the irradiate duration on the bolt surface. Axial force loss of the bolts was affected by the irradiation duration and position. With multiple irradiations on the bolt head, the axial force loss reduced compared with the same irradiation time was confirmed. From the relationship between the axial force change and the treatment duration, axial force loss equations of bolt side laser treatment were suggested based on multiple round irradiations, which can help estimate the axial force loss and make the maintenance plan.

A tuned mass damper (TMD) is a cost-effective tool for targeting the vibration mitigation of a particular mode of structures e.g. first mode of vibration. Structures like a tall building, large span bridges, and other slender structures tend to be easily excited to high amplitudes. In order to deal with the aforementioned issues, TMD could be a good option that can reduce extreme vibration very effectively. The main objective of this paper is to show the implementation of a newly developed TMD to reduce the amplitude of vibration for an excited structure. The TMD was designed such a way that its parameters such as spring stiffness, mass can be adjusted. By tuning the early mentioned parameters, its frequency also be changed to meet the requirements from the structure. In addition, this work investigates the effect of TMD by observing the dynamic response of a two-storey frame structure both experimentally and numerically. Finite element method has been used as a numerical tool to study the dynamic response of the steel frame-TMD system. The time-history (linear) analysis of the frame without (modal mass = 0%) and with TMD (modal mass = 5 and 15%) under earthquake load has carried out and the performances are evaluated and compared. It can be concluded that a significant reduction of response (i.e. displacement) is possible via the newly developed TMD. The maximum percentage of decrease in the displacement found to be reduced by 21% for the modal mass of 5% and 43% for the modal mass of 15%, respectively. Hence, it can be noted that newly developed TMD has potential to use in the real structure for vibration mitigation.

—A total of three reinforced concrete bare frames infilled with brick walls were cyclically tested in this study. Each frame was infilled with a different shape of brick wall. A cyclically loading test was conducted for each specimen so that the hysteretic behaviors as well as the evolution of the failure mode of each specimen can be revealed, especially for the different shape of the infilled brick wall. In fact, the hysteretic behaviors of each specimen can be disclosed by examining the variations of the hysteretic loops of lateral forces-lateral displacement relationships while the evolution of the failure mode of each specimen can be manifested from the test procedure. There was no short column failure of the side column for each specimen although it was constrained by the infilled brick wall. It is affirmed that the stair-step crack pattern is generally consistent with the diagonal force transfer mechanism of brick walls.
