中文摘要：
为了研究强动载作用下钢筋混凝土结构的面力效应问题,在钢筋混凝土梁板结构面力效应的增量方法静力分析模型基础上考虑了材料的平均应变速率效应,通过等效单自由度体系建立了能够分析动载作用下考虑面力效应的钢筋混凝土结构动力响应的增量理论分析方法,并编制了相关的计算程序。将理论计算结果与相关试验数据进行了比较,结果表明：本文方法计算出的结果与试验数据吻合较好,面力效应可以大幅提高钢筋混凝土结构的动抗力,计算和设计中不应被忽略。
英文摘要：
To investigate the compressive membrane action of the reinforced concrete structures subjected to severe dynamic loads,a new analytical method was proposed, which considered an average strain rate effect based on the static incremental method of membrane action and could predict the dynamic responses of concrete beams with the action of membrane force under blast loads based on an equivalent single degree of freedom system. A good consistency was observed between the experimental data and＇the analytical results. The membrane force can increase the dynamic resistance greatly, which can not be neglected in design and calculation of the structure.
