Establishment of Analytical Environment of RC Frame Structures

本研究的目的是建立钢筋混凝土框架结构地震反应分析的分析环境。本文编制的计算程序包括墙单元和柱单元的三维构件模型，为考虑轴向力和双向弯矩之间的相互作用，采用多弹簧模型。采用非线性有限元方法建立了更详细的墙体构件模型。利用该分析环境，对墙体结构的振动台试验进行了模拟研究，分析结果与试验结果吻合较好。本文还对多层建筑进行了地震反应分析，以了解其三维结构性能特征。为了减轻框架结构输入数据的制作负担，本研究还开发了预处理软件。在该软件上，用户可以很容易地通过鼠标设备点击按钮来创建帧数据。

The objective of this study is to establish the analytical environment for the earthquake response analysis of reinforced concrete frame structures.The computer programs developed in this study incluede three dimensionla member models for wall elements and column elements, which adopt the multi-spring models in order to consider the interaction among axial force two-directional flexural moments. More detailed member models for wall elements using the nonlinear finite element method are also developed.Using this analysis environment, we simulated some experimental studies of shaking table tests of wall structures, and got relatively well agreement between analytical results and expermental results. The earthquake response analyzes of multi-story bulidings are also carried out to find out the characteristics of three-dimensional structural behaviors.This study also developed a pre-processing software to reduce the burden of making input data of frame structures. On this software, user can create fram data very easily by clicking buttons by the mouse device.
