山地建筑掉层结构扭转性能分析及抗震设计研究
Study on Torsional Prerformance and Seismic Design of Mountainous Step-Terrace Structure
【摘要】 本文以掉层建筑结构为研究对象,运用ETABS有限元分析软件对不同边界约束条件的掉层建筑结构进行抗震性能的分析。根据不同的嵌固方式建立了相应的简化计算模型,以框架结构实例为对象,研究了陡坎上不同跨数、掉不同层数的掉层建筑结构的抗震性能的规律。
【Abstract】 Taking step-terrace structure as the research object,this paper adopts ETABS program to analyse the aseismatic performance of step-terrace structure in different boundary constraint conditions.In this paper,according to different embedded solid ways,establishes the corresponding simplified calculation model,and take the frame structure as the object,analyse the aseismatic performance patterns on the scarp with different steeps and different locations of step-terrace structure.
