超高结构倾斜框架柱受力特点及设计要点
发布时间：2018-08-22 18:47
【摘要】：超高层建筑常常采用平面尺寸沿高度方向渐缩的体型,能非常有效地减小侧向力,同时有效地控制竖向力的增长,可以充分发挥结构材料的强度和刚度,提高结构的效率和经济性。结构上采用竖向构件沿建筑高度方向倾斜的形式,能达到结构与建筑的融合,并避免复杂的水平转换结构。然而倾斜框架柱在转折处会产生较大水平荷载,引起楼层梁、楼板及外环梁很大的受力。详细分析了倾斜框架柱的受力特点和设计要点,以某400m以上的模拟超高层建筑为案例研究了其解决方案,验证了斜柱水平力的传力途径,并对楼面水平斜撑的设计进行了探讨。
[Abstract]:Super-high-rise buildings often adopt the shape of plane size shrinking along the direction of height, which can reduce the lateral force very effectively, and control the vertical force growth effectively, which can give full play to the strength and stiffness of the structural materials. Improve the efficiency and economy of the structure. The vertical structure is inclined along the direction of the height of the building, which can achieve the integration of the structure and the building, and avoid the complex horizontal conversion structure. However, the inclined frame column will produce large horizontal load at the turning point, which will cause a large force on the floor beam, floor slab and outer ring beam. The stress characteristics and design essentials of inclined frame columns are analyzed in detail. A case study of a 400m high building is carried out to study its solution. The method of force transfer of inclined columns is verified, and the design of horizontal brace on floor is discussed.
