考虑剪力墙基础转动的框剪结构修正计算

Correct Calculation of Frame shear Wall Structure in Consideration of Rotation of Shear Wall Foundation

推导了考虑剪力墙基础转动变形影响的框剪结构的位移和内力计算公式 ,计算中可将考虑剪力墙基础转动引起的内力增量作为一种不利荷载进行内力组合 ,可按剪力墙基础的转动刚度修正剪力墙在基础面的弯矩分配值 ,使计算结果更合理。计算公式能较好地与以往的计算方法衔接 。

This article deduces the calculating formula of displacement and internal force of frame shear wall structure influenced by the rotation deformation of shear wall foundation. In calculation,the internal force increment can be taken as detrimental loads for internal force combination,and the bending moment distribution values on the surface of the foundation of shear wall can be amended according to the rotation rigidity of the foundation of shear wall,so that the calculating results can be more reasonable. The calculating formula can be joined with former calculating formula relatively well,and can be referred to design.
