Evaluation of Seismic Displacement Demand by Response History Analysis and Equivalent Linearization Method for High-Rise RC Buildings Designed Based on Lateral Load-Carrying Capacity Calculation

Abstract

In current seismic design, response history analysis is not required for high-rise buildings shorter than or equal to 60 m which are designed using the lateral load-carrying capacity calculation or the limit strength calculation. The lateral load-carrying capacity calculation is more commonly used among these two design methods but cannot evaluate the displacement demand of buildings explicitly. It is not generally considered whether the story drift for buildings designed based on this calculation method will exceed the safety limit deformation defined by the limit strength calculation. The objective of this study is to clarify seismic displacement demand of a high-rise RC building designed based on the lateral load-carrying capacity calculation. A comparison was made between the story drift evaluated by both response history analysis and equivalent linearization method of the limit strength calculation method and the safety limit deformation.
