Taking the greenhouse as application object , based on the analysis of the test data by the theory of rough sets , and using the theory of structure mechanics , the dissertation presents a new method of optimizing designing of greenhouses " structures based on the rough sets theory 本文以日光温室为试验研究对象，基于rough集理论对试验数据的完备化推理分析，应用结构力学等知识，根据温室载荷设计标准，分析研究了基于rough集的日光温室结构优化设计的方法，提出了一种基于试验数据本身信息的日光温室结构优化设计的新方法。
Instruction about first order analysis method of frames is given by most of the current textbooks on mechanics of structure , and this method is generally used by civil engineers in calculating the internal forces of the frames , however , as the first order analysis does not consider of the additional internal forces caused by the global lateral displacement of the frame , the solution given by this way is obviously not very accurate and safe 目前的结构力学教材一般只讲授框架的一阶内力分析方法，建筑结构设计人员也普遍采用一阶的分析方法对框架进行内力分析。而框架的一阶内力分析未考虑因整个框架侧移引起的内力附加值，这个结果显然是不够精确且偏于不安全的。
