本文是将沿厚度由钢板和混凝土组合而成的钢板混凝土梁化为一等效横观备向同性构件。应用弹性动力学理论和复合板件等效非经典理论,通过动力分析,给出了基本动力方程和构件的等效折合弹性常数。并求得了钢板混凝土梁的固有频率和在横向爆炸载荷作用下的动力反应的解析解。文中对这类构件的力学特性及计算特点作了分析,其结果可直接用于钢板混凝土梁的各种动力及抗爆计算。
In this paper, a steel plate concrete beam composed of steel plates and concrete along the thickness is converted into an equivalent transversely oriented same-sex element. Using the theory of elastic dynamics and the equivalent non-classical theory of composite plates, the equivalent dynamic constants of the basic dynamic equations and components are given through dynamic analysis. The analytical solution of the dynamic response of the natural frequency of the steel plate concrete beam and the lateral explosion load is obtained. The mechanical properties and calculation characteristics of these components are analyzed in this paper. The results can be directly used for various dynamic and anti-knock calculations of steel plate concrete beams.
