摘　　要：分析了钢筋混凝土梁设计成双筋梁比单筋梁经济的原理,通过某办公楼矩形截面简支梁配筋计算,得出了相同配筋的梁按双筋梁计算的承载力比单筋梁计算的承载力高的结论,以推广该双筋梁设计方法,从而给工程增加经济效益。The article analyzes the principle that designing reinforced concrete beam into double reinforcement beam is more economic than into single reinforcement beam, and draws a conclusion that the beam with equal reinforcement has higher bearing capacity according to double re- inforcement beam calculation than according to single reinforcement beam through reinforcement calculation of simply-supported beam with rectangle section in certain official building, in order to popularize the design method of double reinforcement beam and increase economic benefits for the engineering.
