钢筋混凝土梁承受火害的性能研究

Performance-Based Design of Reinforced Concrete Beam Subjected to Fire

本研究旨在探讨两座梁柱复合构件于火害情况下梁的变形行为。柱为三面受火,一座试体(BNC1)使用普通混凝土,另一座(BSC1)使用自充填混凝土,进行高温试验,探讨梁于服务载重作用下,在升温及冷却过程中,钢筋混凝土梁承受火害整体变形情形及其性能,并待高温试验后进行残余强度试验,并探讨其变形。

This study was designed to investigate the two beams composite member in case of fire damage deformation behavior of the beam. The column was on three sides by fire,a test body（ BNC1） using ordinary concrete,and the other（ BSC1） using self-filling concrete,high-temperature experiment,explore the girder in service load under the action of the heating and cooling process,reinforced concrete beam subjected to fire situation and harm the overall deformation properties,the residual strength tests conducted after the high temperature test and wait,and to explore its deformation.
