钢筋混凝土迭合板动力性态的试验研究

Experimental Studies on the Dynamic Behavior of Reinforced Concrete Composite Slabs

本文通过三十九块钢筋混凝土迭合板的爆炸加载试验,对迭合板在弹性和塑性阶段的动力性态进行了系统的分析和研究,其中包括板的自振频率,动力响应,刚度和变形,裂缝和强度,延性比及破坏形式。此外,还对人防工程钢筋混凝土迭合板的设计方法及其在工程中的应用,提出了若干建议。

This paper systematically studies the dynamic elastic-plastic behavior of rein forced concrete composite slabs through the test of thirty nine specimens under the blast-type loading.These are the natural frequency, dynamic response, stiffness and deflection, crack and strength, ductility ratio and the failure type of the slab. In addition, some recommendations are also presented for the design and application in engineering of reinforced concrete composite slabs used in the people's air defence engineering works.
