Analysis of selected shear strength models based on research of beams without stirrups
Faculty of Civil Engineering, Architecture and Environmental Engineering, Lodz University of Technology, Lodz, Poland
The paper presents two theoretical models for calculating shear capacity of beams without stirrups. The analysis refers to slender concrete beams without transverse reinforcement flexurally reinforced with two types of bars: steel and composite (glass fiber reinforced polymer - GFRP). The research program included 29 single-span, simply supported T-section beams without transversal reinforcement. The three point loaded beams (with span to depth ratio a/d in the range of 2.9-3.0 referring to the slender beams). The four times lower modulus of elasticity of the GFRP reinforcement revealed a gentle, progressive shear - tension failure mode, opposite to the abrupt failure mode of the RC beams.
