| The face of a global shortage of land resources intensifying, the rapid growth ofpopulation, as well as ongoing urbanization,making existing buildings of architectural spacebecomes more and more intense, a lot of the construction of high-rise or high-rise buildings tosolve this problem is becoming an inevitable trend.This puts foreword a higher demand onexisting structural system,while composite steel plate shear wall (CSPSW) structure as a newmember of its superior shear resistance is gradually being taken seriously and used in somehigh-rise buildings which reflect the relatively good mechanical performance.However,current research on the composite steel plate shear wall is still shallow,no more specific basisand norms, therefore, it has a important theoretical significance and engineering applicationvalue for stress performance and hysteretic behavior.In this paper, usingANSYS finite element analysis software establishs37compositesteel plate shear walls solid model of single-layer single-span.By changing the concrete slabthickness, height-to-thickness ratio, height-to-span ratio and other parameter settings ofCSPSW,using obtained hysteresis curves, skeleton curves, hysteresis loop area curve andenergy dissipation coefficient curve by finite element analysis data, conducting a systematicanalysis and research under cyclic loading.Also compared CSPSW with SPSW in variousaspects.The results showed that the concrete panels were effective in preventing theout-of-plane buckling of steel plate,preventing the steel plate premature buckling outside theplane which may lead bearing capacity,so can give full play to the good ductility of embeddedsteel,dramatically increased its energy dissipation ability; Height-to-thickness ratio of the steelhas few influence to the CSPSW,when the ratio of steel plate thickness and plate thickness isbetween0.04to0.06, CSPSW will have a good hysteretic behavior;Height-to-span ratio ofthe steel plate have a greater impact on CSPSW, the smaller the height-to-span ratio,higherthe load-carrying capacity is.At last,put forward some design and selection of proposals.This paper established an effective finite element model through a reasonable simplification.Based on the research, put forward some design proposals.Conclusions forfuture CSPSW theoretical research and engineering applications has a certain referencevalue.To laid a good foundation for the structure’s development. |
