高层建筑结构受力的特点1.易发生轴向变形问题高层建筑结构受自身线性结构受力特点,使得其竖向荷载超过一定值后,其竖向作用力影响连续梁弯矩,引起结构轴向变形增大。同时,还可能引起高层建筑的连续梁中间支座处弯矩值发生改变,一般是连续梁负弯矩值明显减小,跨中弯矩值、端支座弯矩值变大。因此对于高层建筑竖向预制构件的下料长度应考虑后期可能发生的轴向变
High-rise building structural characteristics of the force 1. Axial deformation prone to high-rise building structure by its own linear structure of the characteristics of the force, so that the vertical load exceeds a certain value, the vertical force of continuous beam bending moment, causing the structure axis Increase to the deformation. At the same time, it may also cause the bending moment of the intermediate support of continuous beam of high-rise building to change. Generally, the negative bending moment of continuous beam decreases obviously, while the bending moment of mid-span and the bending moment of end bearing become larger. Therefore, the vertical blanking length of tall building vertical prefabricated components should take into account the late axial deformation may occur
