钢筋混凝土结构的弹塑性动力时程分析研究

Elastic-plastic dynamical time-history analysis to reinforced concrete structures

介绍弹塑性动力时程分析的基本原理和分析方法,并以某钢筋混凝土高层双塔连体结构为研究对象,建立大楼结构的分析模型,分别对结构进行了不同设防烈度和不同场地类别下的弹塑性动力时程分析,并进一步考虑P-Δ效应对结构的影响,对结构的抗震性能进行评估。

This article introduces the basic theory and analysis methods of elastic - plastic dynamical time - history analysis, taking example for the high - rise connected twin - tower structures, and takes up the analysis model of building, carries on tile elastic - plastic dynamical time - history analysis vs. the reinforced concrete Structures un- der different fortification intensity and different site classification, the P-Δ effect to structure is taken into account. It can evaluate the capability of earthquake - resistance of the whole structure and guides structure＇ s design of earthquake- resistance.
