夹心保温复合墙板GFRP-Y形拉结件受力性能研究
Research on the mechanical performance of GFRP-Y type tension components in sandwich insulation composite walls
摘要
Abstract
To research the bearing capacity and deflection of GFRP shear connectors in sandwich insulation composite wall panels,with the thickness of insulation layer as the experimental variable,six sets of single GFRP-Y-shaped shear connectors were subjected to shear tests and numerical simulations.The failure modes and load-displacement curve characteristics of the shear connectors were analyzed.Based on a simply supported over-determi-nate beam model,a simplified calculation formula for deflection considering the insulation board was proposed for a single shear connector.The results showed that the failure mode of the sandwich insulation composite wall panels un-der vertical load was shear connector fracture.The ultimate shear capacity of the specimen with an insulation layer thickness of 90 mm decreased by 23.5%compared to the specimen with a thickness of 70 mm,while the relative displacement between the inner and outer face sheets increased by 12.0%.As the insulation layer thickness in-creased from 60 mm to 100 mm,the ultimate shear capacity of the shear connector decreased by 39.1%,and the deflection increased by 44.1%.The research results can provide theoretical basis for calculating the displacement of the outer face sheet in sandwich insulation composite wall panels.关键词
