摘要
建筑抗震设计概念中,地震动激发结构实体自振,把自振反推成有规律且便于分析的静止力形式,即水平地震作用标准值,其可间接地等效反映地震动.再把地震作用标准值等效施加到静止的实体质点上进行结构分析,最终得到建筑整体或构件的地震作用效用.结构分析的通用方法是"振型分解反应谱法",并在该法的基础上引申出"考虑扭转耦联的振型分解反应谱法".
Abstract
In the concept of seismic design for buildings,seismic motion excites the natural vibration of the structural entity,which is then extrapolated into a regular and easily analyzable static force form,namely the stan-dard value of horizontal seismic action,indirectly and equivalently reflecting seismic motion.Then apply the seismic action standard value equivalently to a stationary solid particle for structural analysis,and obtain the seismic effect utility of the entire building or its components.The general method for structural analysis is the"mode decompo-sition response spectrum method",and based on this method,the"mode decomposition response spectrum method considering torsional coupling"is extended.
