在结构设计中,往往要绘制大量的钢筋表。钢筋表中的图形简单,但数据运算和绘表却十分繁琐、费时费力且容易出错。钢筋表绘成之后,一般还需经过描图、校对、晒图或复印才正式成为施工图纸,拖长了设计时间,也提高了设计成本。近年来,价格低廉的低挡微机及其外围设备在各设计、施工单位逐步普及,在各种计算工作中崭 In structural design, a large number of rebar tables are often drawn. The graph in the bar table is simple, but the data calculation and drawing table are very tedious, time-consuming and error-prone. After the rebar table is drawn, it is generally necessary to go through drawing, proofreading, blueprinting, or copying to formally become a construction drawing, which prolongs the design time and also increases the design cost. In recent years, inexpensive low-speed microcomputers and their peripheral equipment have gradually become popular in various design and construction units, and they are used in various calculations.
