Abstract

Abstract

The regular triangular spatial trusses and single-layer cylindrical reticulated shells are integrated into a new roof structure of wave shape，which can give full play to the advantages of the two structures． By analyzing the calculation results of structural design，the structure has a weak seismic response，and through the static calculation the internal force of each bar on the structure greater than that under small earthquakes，strength and stiffness is mainly decided by the static calculation． On the basis of design for the new structure，dynamic elastic-plasticity， linear buckling and nonlinear buckling of considering the initial defects are analysed by using SAP 2000 and ANSYS． The structure has a small amount of plastic hinge under rare earthquake，thus presentingbeam hinge failure mechanism，which satisfies the requirement of ductility design，elastic-plastic displacement angle can satisfy the requirements of the specification，the structure has good anti-seismic performance． The structure shows local buckling in the middle of reticulated shell under stability analysis，and has higher stability bearing capacity． The weak parts of the structure in the design should be strengthened．
- spatial truss,
- cylindrical reticular shell,
- elastic-plastic,
