Foundation scour is a widespread reason for the collapse of bridges worldwide. However, assessing bridges is a complex task, which requires a comprehensive understanding of the phenomenon. This literature review first presents recent scour detection techniques and approaches. Direct and indirect monitoring and machine learning algorithm-based studies are investigated in detail in the following sections. The approaches, models, characteristics of data, and other input properties are outlined. The outcomes are given with their advantages and limitations. Finally, assessments are provided at the synthesis of the research.
<p>Turkey is located on active seismic fault lines. Having this major issue makes the seismic performance analysis a critical step to decide the safety or whether demolishing or reinforcing is more efficient. In this study, a seismic analysis comparison is performed on an existing steel structure via SAP2000 software. The seismic analysis method is Linear Time History Analysis. A comparison of results attained from dynamic analysis is obtained for an existing steel structure serving as a garage in Istanbul, Turkey. The results are demonstrated using graphics where base shear forces as well as lateral displacements obtained for two models are plotted for comparison.</p>
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
