少筋混凝土,就其性质而言,是介于混凝土及钢筋混凝土之间的建筑材料,很多大型水工建筑物是由少筋混凝土建成的。本文系按照1956年修订的4236-48,重新推导了少筋混凝土水工结构在各种荷载作用下的计算公式。这些公式可用于钢筋流限为σ_T=2,500,2,850,3,500公斤/公分~2的构件,这就扩大了技术科学博士拉乌普曼所建议的少筋混凝土计算方法的应用范围。根据本文导出的公式,可以编制便于计算的图表。
Less tendon concrete, by its very nature, is a building material between concrete and reinforced concrete, and many large hydraulic structures are constructed of less-than-reinforced concrete. In this paper, according to 4236-48, revised in 1956, the formula for calculating the hydraulic structure of less-reinforced concrete under various loads is deduced again. These formulas can be applied to members with a steel flow limit of σT = 2,500, 2,850, 3,500 kg / cm ~ 2, which expands the range of applications of the less-tendon concrete calculation method proposed by Dr. Luppumann, Technical Scientist. According to the formula derived from this article, you can prepare a chart to facilitate the calculation.
