摘要
介绍了变截面钢梁优化设计的内容,推导了变翼缘宽度钢梁截面优化设计的步骤及通用公式,并编写了相应的钢梁截面优化计算机程序。算例表明,用本文程序设计的钢梁可比手算法节省钢材10％左右。
This paper presents the contents regarding the optimum design of steel girders with variable cross sections, deduces the procedures and general formulas for the optimum design of cross sections of steel girders with variable flange width, and compiles corresponding computer programs. Calculations show that steel girders designed by the computer program save about 10% steel compared with those designed by hand calculation method.
