장주기 지진에 대한 철근콘크리트 건물의 비선형요구내력 스펙트럼의 제안

초록

The major characteristics of seismic design spectrum is a amplification type for buildings having short period (T) of less than approximately T=0.1. As a result, high-rise buildings with long periods have been widely recognized as safety groups against earthquakes. Recently because the frequency of long period earthquakes has been increased, recently, countermeasures for such earthquakes including the seismic design method and seismic performance evaluation method of high-rise buildings are urgently needed. However, studies on long period earthquakes are being conducted limitedly, and the current situation is that they are being conducted by very few researchers. In this study, the nonlinear required spectrum of RC buildings for long-period earthquakes was proposed to be used as basic data for seismic design and seismic performance evaluation of high-rise RC buildings. The nonlinear required spectrum was proposed by using SDOF nonlinear dynamic analysis using the Origin-Originated model assuming the shear-controlled RC building and the Degrading Trilinear model assuming the flexure-controlled RC building, respectively.
