设计计算程序,就是使电子计算机为设计工作服务的一个手段。就双曲拱桥的设计计算来讲:从假定图式尺寸到进行一次计算,就需20多个工日。通常一个设计,需反复修改设计计算几次,修改设计计算虽然不是头一次设计计算工日的成倍增长,但每修改一次总需好几天。这样要搞好一座双曲拱桥的设计计算工作,就得要一个多月工作时间。显而易见,由于设计计算时间长,计算繁锁,容易造成计算差错,就要求设计人员精力高度集中。在这种情况下,往往只要计算通过了,虽不是很理想也就行了。如果通过设计计算程序,应用电子计算机进行设计计算工作,完成一次完整的设计计算,只需要10来分钟(随跨度大小,略有增长与缩短),若进行主要项目的验算,试算时
Design calculation procedures, is to make electronic computer design work as a means of service. In terms of the design and calculation of the double-curved arch bridge: From the assumption that the pattern size to a calculation, it takes more than 20 working days. Usually a design, need to repeatedly modify the design calculation several times, modify the design calculation Although it is not the first time the design calculation of the working day multiplied growth, but the total change every few days. So do a good job of design and calculation of a double curved arch bridge, you have to work more than a month. Obviously, due to the design and calculation of a long time, the calculation of complicated, easily lead to calculation errors, requires a high degree of concentration of designers. In this case, it is not always ideal, as long as the calculation is successful. If by design calculation procedures, the application of computer design and calculation work, to complete a complete design calculations, only 10 minutes (with the span size, a slight increase and decrease), if the main project checks, trial
