荷载作用下,柱子的轴向变形对多层和高层房屋结构的内力影响很大,因此应考虑柱子的轴向变形影响。在恒载作用下,高层和较高的多层房屋结构的内力分析不能采用常规的先建立整个结构力学模型再将荷载加上去进行分析的方法,而应根据实际的施工建造过程及荷载作作用情况进行分析,否则会对某些杆件内力造成性质上的错误。
Under load, the axial deformation of the column has a great influence on the internal forces of multi-storey and high-rise building structures, so the axial deformation of the column should be considered. Under the effect of dead load, the internal force analysis of high-rise and high-rise multi-story building structures cannot adopt the conventional method of first establishing the entire structural mechanics model and then adding the load to carry out the analysis. Instead, it should be based on the actual construction process and load. Analysis of the situation, otherwise it will cause some members of the internal force of the nature of the error.
