Estimation and Simplified Evaluation of Peak Inter-story Drift Angle during Massive Earthquake for RC Super High-rise Residential Buildings in Japan

Abstract

Database of super high-rise residential buildings in Japan were compiled to grasp their spatial and temporal variation. In addition, extensive response analysis were performed for RC super high-rise residential buildings during huge earthquakes including the 2011 off the Pacific Coast of Tohoku earthquake and the 2016 Kumamoto earthquake. Spatial variation of peak inter-story drift angle (PIDA) of buildings and relationship with response spectra levels was discussed for rapid estimation of building damage. Finally, spatial distribution of PIDA was evaluated using input earthquake motions for the structural design of long-period buildings due to the hypothetical Nankai Trough Earthquake provided by MLIT, showing the validity of the proposed regression equation.
