摘要： 研究了折板型网壳的矢跨比、周边矢高和中心矢高的比值对网壳用钢量的影响，并以网壳用钢量为目标函数，网格数和网壳厚度为设计变量，采用穷举法和0．618法，对20-40m跨度的四角点支承的正方形平面两向正交正放折板型网壳进行了优化分析，给出了不同跨度和不同矢跨比时的最优网格数和最优网壳厚度．研究结果对折板型网壳的设计有一定的参考作用．
关键词： 折板型网壳;  空间结构;  优化分析    
Abstract: The discussion was undertaken about the structural steel consumption affected in different rise／span ratio and different circumjacent／center rise ratio．The optimal calculation of folded plate type latticed shell was developed．considering the steel consumption as an objective function and the number of lattice and the thickness of shell as variables．By using exhaustion method and 0．618 method，some orthogonal folded plate type latticed shell supported on four points were calculated．The optimallattice number and shell thickness were obtained under the different span from 20—40 m ．The result can provide a valuable reference for the design of folded plate type latticed shel1．
Key words: folded plate type latticed shell    space structure    optimal analysis
