摘要
斜交网格筒新型结构体系具有较大的侧向刚度,为建造高层、超高层结构提供了有利条件。然而目前该类型结构的地震非线性性能尚未被明确掌握,导致在结构设计中面临体系构件屈服顺序不明确、外网筒斜柱受力和屈服机制不清楚、外网筒地震失效路径不清晰等关键性抗震问题。通过对典型高层斜交网格筒-核心筒结构地震非线性有限元分析和典型模块子结构的拟静力试验研究,针对该类型体系构件的屈服顺序、斜柱受力和屈服机制以及外网筒的地震失效路径等进行系统研究,明确了该类型体系的上述地震非线性性能。
Diagrid tube structures have advantages for constructing high-rise buildings due to their great rigidity. However the nonlinear seismic performances of this type of structures are not yet clearly understood, so the order of yield of the structure components, inclined column force and yield mechanism and diagrid tube seismic failure path, all of which are quite important problems in seismic design, are not clear. Nonlinear seismic analysis of typical high-rise diagrid tube-core tube structure is carried out and a pseudo-static test on typical diagrid tube module substructure is accomplished to study the components yield order, inclined column force, column yield mechanism and diagrid tube seismic failure path.
