| 摘 要： | 本文按等效连续板分析方法对剪力墙、框架、框架－剪力墙结构分别给出了等效刚度、广义质量、自振频率与振型计算公式，这组公式简单、方便，易于计算，为建筑结构动力设计计算提出了一种可供探讨与发展的方法。文后给出了几个算例，并与有限元或实验结果进行比较，说明符合工程计算精度需要，比现有手算方法有很大程度的改善。

| Abstract: | The computing formulas for equivalent rigidity, generalizedmass, natural frequencies and mode shapes of shear wall, frame,frame-shear wall structures using the analysis method of equivalentcontinuous plate are given respectively in this paper. These formulas are not only simple, convenient and easy to calculate, butalso present a kind of developable approach for dynamic design andcalculation of building structures. Several numerical examples havebeen worked out with their results compared to the finite elementor experimental results, and it is shown that the accuracy of theresults computed by the suggested formulas meet better therequirements needed in engineering practice than those obtainedfrom conventional hand-calculation method |
