| Unbonded prestressed steel reinforced concrete structure is a new kind of structure form which has the advantages of prestressed concrete structure and steel reinforced concrete structure,it has more and more widely in the application of long-span,heavy-loaded,transforming-layer and so on.In this paper,the author has used the ANSYS to design thirteen unbonded prestressed steel reinforced concrete structure which has two-bay and two-storey,analyzed the reaction of the earthquake wave and horizontal cyclic loading.The detailed work is as follows.(1)Compared with the characteristics of UPSRC and PSRC,SRC and steel structure,the existing analysis results are compared.(2)Compared the analysis of UPSRC and SRC of the horizontal displacement limit value,obtained some data reference for subsequent chapters,also verified the feasibility of cooling method in the simulation of prestress.(3)The modal analysis of UPSRC which has two-bay and two-storey is carried out,analyze the dynamic performance of the model is obtained by observing the model in the first few steps.(4)Creating thirteen different sets of UPSRC which has two-bay and two-storey,they have different concrete strength grade,prestressing degree,shear span ratio,column steel ratio,column band ratio,tension control stress.Based on the ANSYS establishment Tianjin wave of APDL language code,to carry out the framework of simulation analyse under earthquake action,research the six kinds of parameter’s change on the influence of the structure of the seismic performance,and some meaningful results are obtained.(5)Based on ANSYS to prepare low cyclic effect of APDL language code,analyzed the hysteresis curve of the thirteen-group frame under the cyclic horizontal displacement load,and the skeleton curve of the structure is investigated.The results are good. |
