一种高层框架振动分析新方法——修正的Holzer迭代法

A new method of dynamic analysis of high-rise frames ——revised Holzer iteration

基于框架侧移柔度系数和等效侧移刚度提出了一种高层框架结构自振频率与振型计算的新方法———修正的Holzer迭代法,使之推广于弯曲型框架,并适用于梁柱任意刚度比情况,可考虑梁柱节点转动和柱的轴向变形,计算简单,精度良好,可供实用。

A new method of the dynamic analysis of high-rise frames, that is called revised Holzer iteration, has been suggested based on the flexibility analysis for multi-storey frames. The method is applied for the arbitrary ratios of beam-to-column,including the influences on rotation of beam-to-column joints and longitudinal deformation of columns.
