Experimental investigation of seismic performance of precast concrete shear walls with overlapping U-bar loop connections

According to the “Specification for Seismic Test of Buildings”44, definitions of relevant mechanical characteristics can be illustrated as follows. The cracking load (Fcr) and cracking displacement (Δcr) refer to the load and deformation at the onset of cracking, respectively. Referring to the corresponding parameters of steel bars shown in Table 3, the specimen was deemed to […]
