摘 要: 介绍了采用箱形梁和格构式钢骨混凝土柱高位转换的高层建筑模型模拟地震振动台试验研究。通过采用微粒混凝土为主要材料制作的1/25高层模型的振动台试验,证实了这种转换层上、下的抗侧移刚度突变不显著,抗震性能较好,该结构设计达到了要求的抗震性能,是安全可靠的。 A shaking table test of high building model with box beams and concrete encased steel columns as transformation floor is introduced in this paper. A 1∶25 scale model of high building was made up of mini-particle concrete. It is proved from the shaking table test of the model that its horizontal stiffness above and below the transformation floor is not changed abruptly, so it has good seismic performance. The high building is proved to meet demand for seismic capacity and is safe in mimic earthquake.
