摘要
采用子结构法和等效悬臂梁法对地震作用下钢管混凝土空间桁架内筒结构进行非线性分析.认为钢管和混凝土这种复合材料的共同工作是可靠的,并考虑了抗压模量与抗弯模量对刚度的影响.
Presents the application of Subsidiary Structure Method and Equivalent Cantilever beam Method to nonlinear dynamical analysis of Concrete Filled Steel Tube(CFST)Space Truss inner Cylinder under earthquake.The CFST is considered as a composite material and the co-work of material is reliable.Compressive modulus and bending modulus affects the stiff-ness of structure.
