Experimental Study on Seismic Performance of Fabricated Steel Foamed Concrete T-Shaped Wallboard

At the present stage, some research results have been made on connection of joints of fabricated reinforced concrete wallboards in China, but there is little research on the connection methods of steel‐concrete composite structure, or methods like welding are directly adopted. On the basis of previous studies, a new type of joint connection method for steel‐concrete composite structure was proposed. Self‐tapping nails are used to connect the steel frames in the wallboard, and this joint connection method is used to splice the web and the flange plate. Concrete postcast strip was set up to produce the fabricated T‐shaped wallboard specimens, and the failure form, bearing capacity characteristics, strain condition, wall displacement, and seismic performance were studied and analyzed, which provided data support for theoretical research. ABAQUS finite element software was used to establish an overall structure model, and the theoretical data and experimental data were obtained through simulation for comparative analysis in which the failure form, bearing capacity characteristics, strain condition, wall displacement, and seismic performance were compared to verify the reliability of the experiment.
