【摘要】 根据高层钢框架结构的实际变形情况,以带刚性节点的十字型梁柱组合单元为计算模型,推导了钢框架结构构件内力与层间位移之间的关系式,并采用sap2 0 0 0程序和有关试验结果验证了公式的可行性和正确性。结果表明,框架钢结构的层间位移主要由梁的转动产生的变形和在考虑P- Δ效应下的柱的变形2部分组成,其中梁的转动产生的变形约70 %～75 % ,而考虑P- Δ效应下产生的柱变形约2 5 %～30 %。本文中推导公式计算结果与试验结果吻合较好,采用带有刚性节点的十字梁柱单元来计算钢框架的侧移是完全可行的。更多还原

【Abstract】 The relationship between the internal force and inter-story displacement of a steel frame structure was educed by a calculation model of a crossed beam and column combined element with rigid juncture based on a actual deformation state of a tall steel frame structure. The induced correlation proved to be applicable and valid. The calculation results indicated that the inter-story displacement of steel frame structure was mainly caused by the distortions of both the beam turning and the column under P-Δ effect, in which the distortion of beam turning occupied about 70%-75%,and that of column under P-Δ effect about 25%-30%.更多还原
