中文摘要：
针对K8型单层球面网壳在阶跃荷载下的响应进行了系统分析,综合多项特征响应指标分析了结构响应特点并给出结构破坏定义.在大量参数分析的基础上,讨论了屋面重量、矢跨比、跨度和初始缺陷对结构破坏临界荷载、结构塑性发展、位移延性系数的关系,为网壳动力破坏机理研究提供了大量基础性材料.
英文摘要：
Research focuses on the responses of single-layer reticulated domes of kiewitt under sudden load. The characteristics of structure responses are analyzed according to multiple index, and the definition of the failure of structures is given. Based on a large amount of parametric analysis, the influence of factors such as the mass of roofs, rise-to-span ratio, span and imperfection on the failure load, the level of plasticity, and the ductility coefficient of displacement are studied, which provides affluent basic materials for the mechanism research of the dynamic failure of reticular domes.
