| 摘 要： | 本文对多层或高层框架结构在天然地基上连续基础考虑上部结构与地基基础共同工作时,提出计算基础内力的弹性杆逐次计算法。 计算模型用弹性杆和刚性杆取代框架柱基础与地基的接触关系。计算方法考虑了柱抗弯刚度的影响、桂轴向变形的影响及结构刚度形成的滞后影响。

An Iterative Elastic-Bar Method Considering Frame Structure-Foundation Interaction |
| |
| Abstract: | An iterative elastic-bar method for calculating the foundation internal stresses of multistorey and highrise frame structures is presented in this paper.A calculating model is adopted which assumes that the contact relations between foundation and soil could be replaced by rigid-bars and elastic-bars could be instead of frame columns. The effects of columns' bendings tiffness, columns' axial deformation, and the lage due to structural stiffness have been taken into account. The method is in good agreement with the practical measurements. |
