在地震工程中有大量的模糊信息和因素需要考虑和处理,特别是地震烈度、场地土分类、结构抗力和结构的设计目标都具有明显的模糊性.它们的模糊性是由于不可能给它们以严格的定义和确定性的评定标准而形成的.本文扼要介绍了在充分考虑事物模糊性的基础上我们所提出的地震烈度模糊综合评定、抗震结构的模糊优化设计和模糊可靠性分析,以及地震作用下结构的模糊随机振动的计算理论.
In seismic engineering, there are a large number of fuzzy information and factors that need to be considered and dealt with. In particular, seismic intensity, site-soil classification, structural resistance, and structural design goals all have obvious ambiguities. Their ambiguity is due to the impossibility of giving them Strictly defined and deterministic evaluation criteria have been formed. This paper briefly introduces the comprehensive evaluation of seismic intensity, the fuzzy optimization design and fuzzy reliability analysis of seismic structures, and earthquakes based on the full consideration of the ambiguity of things. The theory of the calculation of fuzzy random vibration under the effect of the structure.
