摘要
基于宁洱6.4级地震中台站实测的主震记录,分别输入不同的地震动峰值加速度对宁洱县城中的一幢框架结构进行了弹塑性时程分析,并采用延性破坏指标结合实际震害反推出:此次地震中处于Ⅷ度区的宁洱县城地面水平加速度峰值应在0.2g^0.3g范围内。
Based on the main--shock record in the Ning＇er Ms6. 4 earthquake , enter several different peak acceleration to analyze the elastic--plastic seismic response to a frame construction in Ning＇er county. Using the ductility indicators and comparison to the actual earthquake damage we can carry out such result., the. peak acceleration value in Ning＇er county which lies in Ⅷ seismic intensity section should range in 0. 2 g -- 0. 3g in this earthquake .
