基于数据库的无腹筋FRP筋混凝土梁受剪承载力误差分析
Database-based error analysis of calculation methods for shear capacity of FRP-reinforced concrete beams without web reinforcement
摘要
Abstract
A comprehensive database consisting of 461 samples was established considering the shear capacity experimental data from the literature. The effects of six factors, namely the concrete compressive strength, beam width, effective depth, shear span-to-depth ratio, reinforcement ratio, and elastic modulus of fiber-reinforced polymer bars, on shear capacity were analyzed. Furthermore, the prediction performance of each calculation method was evaluated. The results revealed inconsistencies among the calculation methods regarding the consideration of the size effect and the shear span-to-depth ratio, with varying degrees of conservatism in their predictions. Strong correlations existed between the factors and the shear capacity. Among the design provisions recommended by different countries, CSA/CAN-S806-2012 exhibited the most accurate prediction, while ACI440. 1R-2015 demonstrated the highest level of conservatism, and CNR-DT203-2006 exhibited the lowest safety margin. Regarding the calculation models proposed by scholars, Ahmed-2021 reported the most accurate prediction, Alam-2013 was the most conservative, and Mari-2014 exhibited the lowest safety level.关键词
