PC—1500袖珍计算机已经在设计、科研和教学中开始应用。由于它体积小,只有一个公文包那么大;重量轻,不到两公斤重;价格低廉,耗电量少;功能强,运算速度也较快,很受用户的欢迎。本文介绍一种钢结构件的优化方法,在PC—1500计算机上进行优化设计变量的选择,只需几分钟时间,且程序较短,从编制程序到打印出运算结果,不到一个小时。该方法的特点是无需掌握线性规划和非线性规划等优化数学知识。只要掌握了BASIC语言,便可编出优化程序。虽然本方法用于钢结构的设计,但可借鉴它的技巧用于其它方面的设计计算。
The PC-1500 pocket computer has already begun its application in design, research and teaching. Because of its small size, it is only as large as a briefcase. It is light in weight and less than two kilograms in weight. It has a low price and consumes less power; it has a strong function and a fast calculation speed, and it is very popular among users. This article describes an optimization method for steel structures. The selection of optimal design variables on a PC-1500 computer takes only a few minutes and the program is short, from the programming process to the printout of the calculation results, in less than an hour. The characteristic of this method is that it does not need to master the optimization mathematical knowledge such as linear programming and nonlinear programming. As long as you master the BASIC language, you can write an optimization program. Although this method is used for the design of steel structures, it can be used as a reference for other aspects of design calculations.
