“…Pipeline systems generally consist of pipeline structures, fluids, valves, other accessories, and system support systems. Chen S, Xu, and Ye [8][9][10] studied the performance of underground pipeline systems. Numerous researchers have studied flow transmission pipes [11,12], but less attention has been paid to water supply systems, which are functional under normal conditions but easily damaged by earthquakes.…”

Experimental Study on the Seismic Performance of Seismic Bracing in Important Buildings

et al. 2023

View full text Add to dashboard Cite

Important buildings, such as hospitals and nuclear power facilities, must have basically intact pipe systems to function effectively after an earthquake. To study the seismic fragility and failure mechanisms of different typical seismic bracing system types, this paper conducts a comprehensive series of 34 monotonic and cyclic loading tests on four distinct configurations of seismic bracing. The bearing capacity performance and ductility of the components are evaluated thoroughly by using the area (energy) corresponding to the yield displacement, peak force corresponding displacement, and ultimate displacement of the force–displacement curve in the cyclic loading test. Ultimately, the results comprehensively assess the performance of various test specimens, offering suggestions to address the identified issues.
