【摘要】 本文介绍一种以交互方式实现钢筋混凝上梁设计、显示、自动绘图的CAD方法。本设计在计算内力时,采用叠加原理,分别计算各个荷载及支座反力对各截面的作用,改变了对每一截面进行内力平衡的计算方法,简化了计算公式,省去了大量判断,使程序易于实现。更多还原

【Abstract】 One kind of implementation method of CAD for the design,display and autodraw of steel bar and concrete beam is introduced.This system is interactive.This design follows the principle of super-position and respectively considers the effect of each Load andsupport reacting force to any section in calculating the internal forcesof a beam.Comparing with the way of internal forces balance ofsections,this method has the advantage of making the computingformulas simplified,thus a large amount of work on determinationis saved and it makes the program easier.更多还原
