【摘要】 提出等效单自由度体系的概念,阐述了等效的前提条件,叙述了两大不同的等效模式,着重分析了不同侧移模式和水平荷载分布模式对等效体系建立的影响,指出等效参数求解中存在的问题,最后对框架结构的等效转换简化计算提出建议,并对适用的计算方法作出探讨。更多还原

【Abstract】 Concept of equivalent single-degree-of-freedom(SDOF) system is proposed.Based upon introduction of prerequisite requirement of equivalence two different equivalent modes are presented.This paper mainly analyzed the influences of various lateral displacement mode and horizontal load distribution on equivalence.Questions existed in finding solutions of equivalent parameters are discussed.In the end suggestions are proposed for simplified equivalent transformation calculation of frame structure.更多还原
