摘要/Abstract

摘要： 在单层网壳的优化设计中,传统的设计对许多因素的不确定性没有予以考虑,有一定的局限性.本文在充分考虑了单层网壳优化设计参数的模糊性的基础上,建立了模糊优化设计的数学模型.模型解决了多目标函数及应力控制标准的模糊性.单层网壳的模糊优化设计结果表明了模型的合理性和可行性.

关键词: 单层网壳；模糊优化设计；模糊可靠度约束；

Abstract: In the optimization design of single layer latticed domes,the used mathematical models without considering uncertain factors have some extents of limitations.Based on the considering of fuzzy and random quality of each design parameter of single layer latticed domes,a new multi-objection optimization model is established.In this model,the fuzziness of multi-objective function and the stress control criterion are solved.The computation results for single layer latticed domes demonstrate that the model is reasonable and feasible.
