EVG-3D墙板耐火性能及火灾加固后的抗震性能试验研究

Study on fire resistance and anti-seismic properties of EVG-3D wall panel after fire disaster reinforcement

介绍一种新型墙材——EVG-3D墙板。通过火灾试验以及火灾墙板加固后进行拟静力试验,研究墙板的耐火极限、火灾加固后的破坏形态、承载力、刚度、延性比、滞回耗能等性能。通过计算分析墙体的抗剪承载力,表明火灾加固后的墙板仍具有良好的抗剪性能,可作为承重墙使用。

This paper introduces a kind of new wall materials,which is EVG-3D wall panel. Based on the test of the fire resistance of the wall panel and the quasi-static test of fire wall reinforcement,the fire resistance of wall panel, as well as the failure mode, bearing capacity,stiffness,ductility ratio,and hysteretic energy dissipation after fire disaster reinforcement were studied. And through the calculation and analysis of the shear capacity of the wall,the results show that the fire wall panels still have good shear performance,can be used as load-bearing wall.
