主要对高层框架结构在常规条件下、地表变形下进行对比分析,得出建筑物主要构件在只有地表变形下内力的变化规律。同时对建筑物在地表变形作用下的基底位移、水平方向的位移进行了对比分析,得出建筑物基底位移在地表曲率变形下呈不规则的抛物线型,水平方向的位移在地表变形下值很小。 Mainly on the high-rise frame structure under normal conditions, the surface deformation of the comparative analysis of the main components of the building obtained in the surface deformation of internal forces under the law of change. At the same time, the contrastive analysis of the basement displacement and the horizontal displacement of the building under the deformation of the ground surface shows that the displacement of the basement of the building is irregularly parabolic under the curvature of the surface. The displacement in the horizontal direction is very low under the surface deformation small.
