Retaining Wall Calculation Verification – Reinforced concrete cantilever – 英制
The data used in this verification example and the results to compare with SkyCiv 挡土墙设计软件 were taken from: 钢筋混凝土设计手册, ACI SP-17(14), 卷. 2, p. 24. This model is particularly interesting because it is a cantilever concrete Retaining Wall with no surcharge applied on the active soil zone.
