摘要 本文提出了一种使用形状因子对刚度设计的简单结构布局的质量效率进行排序的方法。针对简支和集中加载结构的示例荷载工况，导出了三种不同框架和七种不同梁的形状系数。形状因素显示了结构效率如何受到四个不同设计方面的影响：(a) 高度限制的严重性、(b) 应力的均匀性、(c) 高度的利用和 (d) 荷载传递原理。外形因素可用作初步设计工具，帮助选择和设计结构概念。
Abstract This paper presents a method for ranking the mass efficiency of simple structural layouts for stiffness design using form factors. Form factors are derived for three different frameworks and seven different beams for an example load case of a simply supported and centrally loaded structure. The form factors show how structural efficiency is affected by four different design aspects: (a) severity of height constraint, (b) uniformity of stress, (c) utilization of height and (d) principle of load transfer. Form factors can be used as a preliminary design tool to help select and design structural concepts.
