地震作用下沿高变刚度框剪结构的计算方法

本文在对框剪结构连续化处理的基础上，在框剪结构刚度变化区间进行离散化，推导出框－剪单元在考虑刚度变化和剪切变形影响时的内力，位移关系式，给出了沿高变刚度框剪的结构地震反应计算方法。本文给出了算例，说明考虑沿高变刚度对框剪结构内力及位移的影响是必要的。

The Computation Method for Earthquake Excited Frame Shear Wall Structure with Variable Rigidity along Height

Based on the continuum hypothesis of frame shear wall elements,the structures are dispersed between regions with different lateral rigidities Formulae for inner forces and displacememts of frame shear wall elements are developed,in which the effects of lateral rigidity and shear deformation of structure are considered The computation method for earthquake excited frame shear wall structures with variable lateral rigidity along height is presented The example given here shows that it is essential for the frame shear wall structure to take the lateral rigidity variety along height into account
