摘要
混凝土框架结构中关键竖向构件在爆炸、撞击等偶然荷载作用下失效后,可能引发整体结构的连续倒塌. 笔者对国内外角柱失效下的混凝土框架结构连续性倒塌试验和理论研究成果进行了总结,分析了结构倒塌过程中 抗力机制对结构抗倒塌性能的影响,并对结构抗倒塌性能的研究进行了展望.
The failure of key perpendicular bearing members in concrete structures caused by accidental loads such as explosion and impact could trigger a devastating progressive collapse of the global structures. This paper reviews the experimental and theoretical research results on progressive collapse of reinforced concrete frame subjected to a loss of ground comer column scenario, and the resistance mechanisms during the collapse as well as their contributions to the collapse resistance. Finally, the prospective research directions on the structural col-lapse are highlighted.
