近几年在全国,特别是北京市,高层建筑有了很大发展,建筑形式也多种多样。筒中筒结构是近几年采用较多的一种较新的结构体系。由于这种结构能提供较大的空间,使建筑布置比较灵活,受到了建筑师们的的青睐。为进一步搞清筒中筒结构中框筒部分在水平力作用下的空间工作性能、抗震性能、破坏特征及不同刚度阶段的动力特性,我组于1985~1986年做了一个十六层1/6比例的试验模型。模型高8m,平面为2.4×2.4m,总重量61t(其中自重13t)。这个模型是目前国内最高的,在世界上也较少见。模型规模大,测
In recent years, high-rise buildings have developed greatly in the country, especially in Beijing, and the forms of construction have also varied. The tube-in-tube structure is a relatively new structural system that has been used in recent years. Because of this structure can provide a larger space, make the building layout more flexible, has been favored by architects. In order to further understand the spatial work performance, seismic performance, damage characteristics, and dynamic characteristics of different stiffness stages of the frame section of the tube structure in the tube in the horizontal force, our team made a sixteen-story 1/6 from 1985 to 1986. Proportional test model. The model is 8m high, the plane is 2.4 x 2.4m, and the total weight is 61t (of which the weight is 13t). This model is currently the highest in the country and is also rare in the world. Large scale model
