Abstract

The mechanical behaviour of composite materials at high temperatures has always been a hot topic for scientists to research. This paper studies the behavior of a new reinforced concrete composite beam at elevated temperatures. The fire condition experiments were carried out using the experimental method of heating and reloading in the high-temperature furnace, as well as the method of finite element analysis. The experimental results show that wrapping fireproof basalt mat can effectively help the structure bearing 30% more load by slowing the heating speed, while FEM presented that simple wrapping is not enough to withstand high temperatures exceeding 600 ?, the thermal insulation performance of fireproof materials may have adverse effects on the structure itself. Combining the results of the FEM heating simulations with those of the laboratory heating, the FEM heating simulations were capable of revealing the realistic situation, which provided a positive contribution to the accuracy of the results of the subsequent thermal loading experiments. This research offers a perspective prediction in fireproof buildings.
