摘要
底部多层大空间框支剪力墙结构自振频率和振型的求解是十分复杂的工程问题。将底部多层大空间框支剪力墙结构看作变刚度(截面)的弯-剪杆,并将结构简化为具有多个自由度的体系,在此基础上运用柔度矩阵法求解结构频率和振型。详细的介绍了柔度矩阵法的解题思想和计算步骤,并通过算例证明柔度矩阵法是一种简单而又精确的求解底部多层大空间框支剪力墙结构自振频率和振型的方法。
It is complex to calculate the natural frequency and modal of shear wall structure supported on frame-shear wall structure in civil engineering. In this text, the whole structure can be looked upon as an asymmetric bend-shear bar; than it is equivalent to a system with several degrees of freedom, the natural frequency and modal of the whole structure can be calculated by flexibility matrix method on the base of that. This method is proved that it is accurate and convenient enough for calculating the natural frequency and modal of shear wall structure supported on frame-shear wall structure by examples.
