Influence of shear‐axial force interaction on the seismic performance of a piloti building subjected to the 2017 earthquake in Pohang Korea

Abstract: This study aims to investigate the influence of shear‐axial force interaction on the seismic performance of a piloti‐type building subjected to the Pohang earthquake. For this purpose, a four‐story piloti‐type building in Pohang, Korea whose columns were brutally damaged by the 2017 Pohang earthquake, one of this country's strongest earthquakes in modern history, was chosen as the object of the study. Columns of this piloti‐type building were designed with insufficient transverse reinforcement, resulting in an… Show more

“…In fact, the torsional effects caused by additional shear walls should be considered under the condition of bidirectional input ground motions. More details on such effects under the same piloti building model can be found in [45]. Subsequently, the seismic responses of the columns are presented and discussed in terms of hysteretic curves, stiffness degradation, and interstory first ratio.…”

“…Without a proper model parameter predictive equation, a model cannot be used to simulate the load-deformation response of arbitrary sections. Some researchers [22][23][24] attempted to resolve the nonadaptive behavior of conventional LPMs by using Zeus-NL. 25 In this software, a total of six backbone curves can be predefined with respect to the expected levels of axial load.…”

“…However, there is a lack of studies that include interaction of shear force with axial load and moment in plastic hinges for progressive collapse assessment of buildings. It is well known that plastic hinge capacity is affected by M-V interaction (Dang-Vu et al, 2020;Mander et al, 1993;Recupero et al, 2005;Russo et al, 1991). (Lee & Elnashai, 2002) noted that considering flexural and shear failures independently may result in overestimation of member capacity.…”
