爆炸荷载作用下典型建筑构件破坏特征试验研究

摘要

针对建筑物的典型结构砌体墙和玻璃在爆炸载荷作用下的破坏特征问题，进行了爆炸载荷作用下的破坏特征试验研究。首先通过对比试验证明了碳纤维对砌体墙的加固作用，然后通过数值模拟方法研究了不同纤维厚度对砌体墙抗爆性能的影响，当碳纤维厚度处于0.1~0.5 mm区间内加固效果最为明显。最后对钢化夹层玻璃和普通夹层玻璃的抗爆性能进行试验，试验结果表明钢化夹层玻璃的抗爆性能明显优于普通夹层玻璃。%Aimed at the damage characteristics of the typical masonry walls and glass of buildings under explosion load, the experiment for the damage characteristics is performed under blast load. The reinforcement effect of carbon fiber on the ma⁃sonry walls was verified with the contrast test. The influence of different fiber thickness on antiknock performance of masonry walls is studied by means of the numerical simulation method. When the thickness of the carbon fiber is in the range of 0.1~0.5 mm,the reinforcement effect is most obvious. The antiknock performance of the tempering sandwich glass and ordinary sand⁃wich glass was tested. The experimental results show that the antiknock performance of the tempering sandwich glass is superior to that of the ordinary sandwich glass.
