COMPARISON OF RELEVANT CHARACTERISTICS OF OPTIMIZED PORTAL FRAME WITH TRADITIONAL DESIGN AND A CHOICE OF SEVERAL REASONABLE DESIGN PARAMETERS
-
摘要: 采用内罚函数方法对30 m跨变截面门式刚架优化设计的相关特性与常规方法设计进行比较。通过内承载力与控制截面节点相关设计参数的相互耦合作用，达到设计目标函数的理想值。由案例相关特性比较可知，优化设计一般节能可在15%～30%。同时提出了在优化设计时应该注意的几个合理参数的选择。Abstract: It can be known from the comparison of relevant characteristics of the optimized design by penalty function method for a 30 m span tapered portal frame to the design by the conventional method.So as to achieve the ideal value of the design objective function through the interaction of relevant design parameters for the joints of the inner bearing capacity and the controlled sections.It can be seen by the contrast of relevant characteristics of examples that generally 15%~30% energy can be saved by the optimized design.At the same time, it is proposed that the choice of several reasonable parameters needing attention during optimizing a design.
