论结构抗震的鲁棒性

Introduction of robustness for seismic structures

介绍了结构鲁棒性的概念及提高结构鲁棒性对避免结构在罕遇地震下垮塌的重要意义。分别从抗震结构体系、结构承载力与延性、结构破坏模式以及赘余构件等几方面讨论了提高结构抗震鲁棒性的措施,给出了相应的设计建议。

The concept of robustness of structures and its importance for preventing collapse against strong earthquake are firstly introduced. Then the influence aspects to the robustness of seismic structures, including structural systems, failure modes, strength and ductility of structure, and redundancy elements, are discussed. The approaches to increase the robustness of seismic structures are suggested.
