本文针对重物高空坠落高速撞击钢筋混凝土楼 (屋 )盖时的结构损伤分析 ,根据弹塑性靶板理论以及动能守恒定理提出了一种计算板及周边梁中内力的简化手算算法。计算结果和现场实测资料吻合 ,说明该算法可以用于实际工程
In this paper, aiming at the structural damage analysis of heavy objects impacting on high-speed impact of reinforced concrete building (roof) under high altitude, a simplified algorithm for calculating the internal forces in the calculation board and the surrounding beams is proposed according to the theory of elasto-plastic target plate and the conservation of kinetic energy. The calculated results are in good agreement with the field data, which shows that the algorithm can be used in practical engineering
