In this study, characteristics of multi-story reinforced concrete frames subject to lateral loads are performed to consider the effect of in-elastic behaviors of beams, columns and walls. For frame analyses, it is proposed the concept of simplified uniform buildings, and the equations following relationships between lateral load and displacement are derived to in-elastic three-moment equation and three-deflection equation. All of beams, columns and walls subject to bending moments is replaced by members with varying plastic zone, which is represented by relationships between bending moment and curvature.The results obtained in this study are summarized as followings. 1. For uniform frames, it is examined the ratio S_1 of strength on columns to strength on beams at beam-column joints. The parameter S_1, the required strength ratio, which controls overall collapse mechanism of frames, may be necessary more than 1.3 in this study. 2. The parameter S_2, the ratio of strength on base of wall to total strength on all beams is directly associated with in-elastic behaviors of frames with walls. Especially, lateral load capacity is dependent on the parameter S_2.

本研究针对多层钢筋混凝土框架在侧向力作用下，考虑梁、柱、墙的弹塑性行为的影响，进行分析。在框架分析中，提出了简化均匀建筑物的概念，并将框架的侧向荷载-位移关系式导出为弹塑性三弯矩方程和三挠度方程。所有受弯矩作用的梁、柱和墙均由塑性区变化的构件代替，塑性区变化可用弯矩与曲率的关系表示。1.对于均质框架，本文研究了梁柱节点处柱与梁的承载力之比S_1。在本研究中，控制框架整体倒塌机理的参数S_1（所需强度比）可能需要大于1.3。2.墙底承载力与梁总承载力之比S_2与带墙框架的弹塑性性能直接相关。特别地，侧向承载能力取决于参数S_2。
