提出了一种考虑任意支承条件和非线性影响的钢筋混凝土梁和单向板在剧烈动力荷载作用下的数值分析方法。此外，还对钢筋混凝土构件在局部动力荷载作用下的性能和模型进行了研究。对于动力分析，有必要计算结构单元在每个加载步长的变形构形，并使用该信息来计算等效动力模型的参数。该方法建立在相应的结构抗力函数的基础上，然后将其用于单自由度分析。对其他研究人员测试过的一些钢筋混凝土结构构件进行了分析，以评估该方法的有效性和论证了该方法的有效性。对冲击荷载作用下的钢筋混凝土梁和爆炸作用下的钢筋混凝土墙进行了分析。
A numerical approach is proposed for the analysis of reinforced concrete beams and one‐way slabs under severe dynamic loads, accounting for arbitrary support conditions and nonlinear effects. In addition, the behavior and modeling of reinforced concrete members subjected to localized dynamic loads have been examined. For a dynamic analysis, it was necessary to compute the deformed configuration of the structural element at every load step and to employ that information for computing the parameters of an equivalent dynamic model. The approach is based on the development of corresponding structural resistance functions, which are then employed in single‐degree‐of‐freedom analyses. A number of reinforced concrete structural elements, that were tested by other investigators, have been analyzed to evaluate the validity and demonstrate the effectiveness of this approach. The analysis was performed for reinforced concrete beams subjected to impact loads and for reinforced concrete walls subjected to detonations ...
