EXPERIMENTAL STUDY ON SHEAR PERFORMANCES OF PREFABRICATED COLD-FORMED THIN-WALL STEEL WALLS FILLED WITH LIGHT WEIGHT POLYMER MORTAR[J].

To improve the performances of shear walls and the assembly degrees, a novel type of prefabricated cold-formed thin-wall steel walls filled with light weight polymer mortar (LPM) was developed. The shear performance test for six shear walls were conducted. The failure modes, load-displacement relations, shear capacity, ductility were studied comprehensively. The influence factors including presence or absence of cement-fiber panels, mortar types, wall thickness, and the layers of steel wire gauze were studied. The test results showed that the panels and mortar types had great effect on the failure modes, shear bearing capacity and ductility of shear walls, the panels on both sides could increase the bearing capacity of shear walls by 74%. The bearing capacity of shear walls filled with cement-based LPM could be 38.4% higher than that of walls filled with gypsum-based LPM. The layers of steel wire gauze had no obvious influence on the shear bearing capacity but had a great influence on the ductility of wall panels.
