Changes in the thermomechanical properties of fiber-reinforced concrete (FRC) exposed to fire are fundamentally affected by the type and volume fraction of fibers. Because the loss of FRC load-bearing capacity is mainly caused by structural damage, a new numerical procedure based on a modified method of discontinuous boundary elements (DBEM) is proposed, which is modified to include thermomechanical processes in concrete together with the effect of fibers. DBEM allows the reader to visually track the location and extent of material damage.

不连续边界元法升温对混凝土结构的影响

暴露于火中的纤维增强混凝土 (FRC) 的热力学性能变化从根本上受纤维类型和体积分数的影响。由于 FRC 承载能力的损失主要是由结构损伤引起的，因此提出了一种基于不连续边界元 (DBEM) 改进方法的新数值程序，该方法被修改为包括混凝土中的热机械过程以及纤维的影响. DBEM 允许阅读器直观地跟踪材料损坏的位置和程度。
