本文评述了以往少筋混凝土结构的计算方法，进行了素混凝土、少筋混凝土及钢筋混凝土受弯构件受力性能的对比试验。根据试验结果，给出少筋混凝土破坏过程为二阶段的假定，建议了相应的计算方法。引用半概率法的概念；论证了少筋混凝土的安全度。 对少筋混凝土新计算法的适用范围及经济效果进行了论述。
This paper reviews the calculation method of the formerly less-reinforced concrete structures, and conducts comparative tests on the mechanical properties of plain concrete, less-reinforced concrete and reinforced concrete flexural members. According to the test results, the assumption of the two-stage failure process of the less-reinforced concrete is given, and the corresponding calculation method is proposed. Cite the concept of semi-probability method; demonstrate the safety of less-reinforced concrete. The application scope and economic effects of the new calculation method for less-reinforced concrete are discussed.
