摘要
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.
