These methods have been developed by modifying the ACI 318-99 shear capacity formula for steel-reinforced concrete beams to account for the difference in the axial stiffness of GFRP and steel bars. It has been shown that the theoretical predictions of the shear capacity obtained from these ...
This study presents a simplified design formula for the shear capacity of the prestressed concrete (PC) beams strengthened by steel plates. Based on the equilibrium equations of inclined sections of the beam, a simplified expression of shear contribution of steel plates was deduced considering the sh...
In this article, the shear behavior of lightweight concrete beams reinforced with glass fiber-reinforced polymer (GFRP) bars is examined. Here, in order to investigate the effect of bar type on the shear strength, the GFRP bar was used as the longitudinal bar. In total, eight concrete beams...
Referring to formula for shearing capacity of steel reinforced concrete beam and comparison of test results,author points out formula for plastic shearing capacity of partially encased composite beam. 考虑了钢梁腹部钢筋混凝土对组合梁抗剪性能的影响,给出了部分外包简支组合梁弹性理论计算时的剪应力分析方法...
In this paper we propose a new simple size effect formula for the shear strength of RC beams without stirrups using compression field theory and fracture mechanics concepts. The nominal shear strength of a concrete beam, [v.sub.c], is a function of many variables such as effective depth, ...

used an ANN to predict the shear strength of fiber-reinforced concrete beams. The results show that the ANN is better than the empirical formula. Vu et al.40 developed a combined least squares support vector machine model (LS-SVM) to predict the punching shear capacity of concrete slabs. ...
Steel Reinforced Concrete ( SRC ) has been used in highrise building because of its excellent aseismic behaviour. In this paper, the experimental results of 4 SRC beam-column subassemblages composed of I-shaped steel subjected to reversed cyclic loading are described and compared with conventional ...
The calculation formula for bearing capacity was verified and further corrected through the current study of the influences of different parameters on the shear behavior of concrete T-beams reinforced with surface-embedded FRP. Tests were conducted on 14 beams reinforced with FRP tendons, including ass...
Moreover, shear span ratio, high strength concrete and the dimension effect has not been considered in the formula development of shear capacity. In order to improve the current design code, future research should consider additional factors such as high strength concrete (HSC), fibre types, and...
