Fenestration and glazing: Seismic performance specification considerations

By Amy Becker Photo courtesy Fenestration and Glazing Industry Alliance (FGIA) Specifiers and design professionals should always consider seismic performance attributes for buildings in areas that previously have experienced the damaging effects of earthquakes. After seismic activity has occurred, building occupancy and soil conditions may lead to seismic mitigation even if there is novisible damage. […]

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 […]
