Experimental Study on Seismic Behavior of Coupled Steel Plate and Reinforced Concrete Composite Wall

The coupled steel plate and reinforced concrete (C-SPRC) composite wall is a new type of coupled-wall system consisting coupling beams (SCBs) that join two SPRC walls where the shear (SPSW) embedded in RC wall. Although C-SPRC has been extensively constructed high-rise buildings seismic regions, research on its behavior rarely reported. No code provisions are available for directly guiding preliminary design such systems. In research, three 1/3-scaled subassemblies including one-and-a-half stories half-span SCB were tested under simulated earthquake action, considering fabrication method SPSW shear-span ratio as test variables. prime concern was to evaluate influences those popular construction parameters Deviating from beam tip loading used conventional subassembly tests, lateral cyclic load this applied at top pier so behaviors both SCBs could be examined. results exhibited great performance with mechanism fully developed. energy dissipation capacity inter-story deformation assembled roughly 9.4% 13.2% greater than welded SPSW. Compared 2.2, interstory-deformation one 2.0 increased by approximately 13.4%, while decreased 10.9%. further compared simulation using proven-reliable finite element analysis respect hysteretic curves, skeleton capacities failure patterns.
