The splitting failure of underground caverns of large hydropower station is a common phenomenon that was not accounted for theoretically so far, which is one of the important factors affecting the safety of underground construction and the long time running stability. Long-term load conditions and great depth are considered to be the main factors that lead to the creep deformation of underground hard rock mass. Therefore creep tests under long-term load conditions are conducted for the purpose of studying the creep properties of the deep hard rock mass. An important hydropower station is taken as the research background project, and the Granite is taken as the research object to carry out the long-term creep test. During the test, the effect of long-term load conditions of hard rock is mainly recorded. Based on the results of the systematic analysis, it is concluded that the mechanical properties of granite are largely affected by high stress: (1) The creep process of granite can be divided into three stages: the transient creep, the steady creep, and the accelerated creep, with different strain rate in each creep region. (2) The granite generates instantaneous deformation at every loading level, the higher the confining pressure, the greater the initial transient strain. (3) The creep deformations of specimens increase with time and stress, it begins to appear an obvious creep deformation when the stress level reaches a certain value, the higher the confining pressure, the greater the creep deformation, and the earlier the creep phenomenon. (4) The higher the confining pressure, the shorter the creep duration, and the more liable to be broken. (5) With the increase of confining pressure, the rock tends to shear failure.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116467574","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, it is necessary to predict the RIDR max of Steel Moment-Resisting Frames (SMRFs) with high reliability by employing powerful Intensity Measures (IMs). This study investigates the efficiency and sufficiency of scalar-valued IMs for predicting RIDR max of two sets of the 3-Story, 6-Story, and 9-Story SMRFs with and without using linear Fluid Viscous Dampers (FVDs). Incremental Dynamic Analysis (IDA) was performed with considering RIDR max as engineering demand parameters using Opensees. Results of analysis showed that two scalar-valued IMs of IM M (α=0.5 ) and Sa avg M-D had lower values of the variations of standard deviation of natural logarithm of IM of RIDR max , σlnIM RD , which shows the efficiency of these IMs. Moreover, these scalar-valued IMs achieved higher p - values with respect to seismic ground motion features of M, R, and Vs30, which shows the sufficiency of assumed IMs. Therefore, two scalar-valued IMs of IM M (α=0.5) and Sa avg M-D are proposed as optimal scalar-valued IMs for predicting the RIDR max of SMRFs","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127905057","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cement particles undergo a series of chemical reactions with water molecules to form several cement hydration products during curing. However, the low water to cement ratio in concretes, such as high-performance concrete (HPC) and ultra-HPC with supplementary cementitious materials, lack enough water molecules for the curing process to complete, resulting in autogenous shrinkage and hence early age micro cracking. Mitigation of shrinkage is a mandatory requirement in sustainable construction projects, which can be achieved through proper curing of HPC. This paper reports the effects of superabsorbent polymer (SAP) as internal curing material on the properties of hardened HPC monitored by N 2 - adsorption, X-ray diffraction (XRD), and FT-IR spectroscopy after 28 days of curing in water and air. The N 2 adsorption analysis showed an increase in total porosity of the specimens with SAP due to the formation of more macro pores. Higher amounts of Ca(OH) 2 were detected in samples with SAP by the X-ray diffraction analysis indicating the formation of more cement hydration in those specimens.","PeriodicalId":101411,"journal":{"name":"International journal of structural and civil engineering research","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131025932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Moreover, specific systems are necessary to account for the factors influencing the implementation of construction safety. Proportionately, integrating advanced technologies such as Building Information Modelling/Management (BIM) manifests as one of the strategies for mitigating construction safety programs. Thus, this research aims to expand previous research and fill the gaps in current measures taken for adopting and implementing BIM, focusing on improving construction safety management and implementation. This study presents a framework that incorporates 4D Simulation and automation features of BIM. The framework aims to overcome challenges related to regulating construction schedules, taking into account weather conditions, and adhering to standard safety codes in the construction safety planning process. The ultimate goal is to promote sustainable construction safety management.
