主 题：Sandwich wall panels fire behavior fire test finite element modeling residual capacity
摘 要：To investigate the temperature field and residual bearing capacity of the sandwich wall panels with GFRP skins and a wood-web core under a fire,three sandwich walls were *** of them was used for static load test and the other two for the one-side fire ***,temperature probe points were set on the sandwich walls to obtain the temperature ***,the model of the sandwich wall was established in the finite element software by the method of core material stiffness *** temperature distribution and performance reduction of materials were also *** residual bearing capacity of specimens after fire exposure were simulated considering the effects of web spacing,wall panel thickness and fire exposure *** the sandwich wall panels were stressed by eccentric compression after a fire,the residual compressive strength of the wall panel after the fire can be calculated through the eccentric loading *** with the numerical results,it can be concluded that the effectiveness of calculation method of residual bearing capacity after fire exposure was proved.
