Study on Seismic Performance of Prefabricated Light Steel Frame-composite Light Wall Structure
This paper mainly compares the mechanical characteristics of prefabricated light steel frame-composite light wall structure under the action of low weekly repeated load and the conventional light steel frame,and deeply explores the influence of fly ash layer thickness on the seismic performance of prefabricated light steel frame-composite light wall structure.The results show that compared with the light and empty frame,the damage load of prefabricated light steel frame-composite light wall structure increases by 85.5%,the damage stiffness by 18.5%,and the cumulative energy dissipation by 83.2%;After filling fly ash,the failure load of prefabricated light steel frame-composite light wall structure is 18.5%,the damage stiffness changes not much,and the cumulative energy dissipation increases by 28.6%.In general,filling with fly ash can enhance the seismic performance of prefabricated light steel frame-composite light wall structure.
