基于可靠度理论的小城镇工程结构抗灾设计体系

A design system for the disaster-resistance of engineering structures of small towns based on reliability theory

文章提出了小城镇工程结构抗灾设计的目的、原则,为小城镇的抗灾设计提供了切实可行的设计准则,分析并提出了小城镇工程结构抗灾性能指标体系,为小城镇工程结构抗灾可靠度的理论分析提供了分析变量,建立了在各种灾害作用下小城镇工程结构抗灾可靠度理论的分析模型,为小城镇基础设施的防灾减灾的进一步研究提供理论依据。

A disaster-resistant design goal and four disaster-resistant design principles of the engineering structures of small towns are proposed as a practical reference for the disaster-resistant design of small towns. An iridex system of disaster-resistant performance of the engineering structures of small towns is also proposed, which can provide basic variables for theoretical analyses of disaster-resistant performance of engineering structures of small towns. Finally, models of disaster-resistant reliability theory of engineering structures of small towns under the action of the disasters are put forward for further study.
