Experimental study on pre-damaged RC beams shear-strengthened with textile-reinforced mortar (TRM)

Liying Guo et al.

Summary: This paper reports on an experimental investigation of pre-damaged reinforcement concrete (RC) beams strengthened in shear with textile-reinforced mortar (TRM). The results indicate that TRM strengthening can restore the mechanical properties of pre-damaged RC beams and increase the shear capacity of the beams. However, the shear capacity of pre-damaged strengthened beams is smaller than that of non-damaged strengthened beams, and it decreases with the increase of sustained load on the beams.

Flexural behavior of RC beams externally bonded with polyethylene terephthalate (PET) fiber reinforced polymer (FRP) laminates

Rami A. Hawileh et al.

Summary: The experimental study demonstrated that RC beams strengthened with PET-FRP showed significant strength enhancement and higher ductility compared to beams strengthened with conventional CFRP and unstrengthened beams. PET-FRP is a promising strengthening material that improves structural performance and provides a sustainable alternative to traditional FRP strengthening systems.

Material comparative analysis of crack-bridging degradation of SFRC structural beams under flexural fatigue loading

Mohamed Adel et al.

Summary: This study experimentally investigates the influence of several material parameters on crack-bridging degradation in steel fiber reinforced concrete (SFRC) structural beams under constant and variable amplitudes of flexural cyclic loading. The results show that higher concrete strength and fracture energy contribute to lower crack-bridging degradation rates, longer fatigue life, and higher residual capacity. Double hook steel fibers have a relatively insignificant effect compared to single hook fibers in controlling crack-bridging degradation rates and the flexural cyclic responses of SFRC beams. Lower longitudinal reinforcement ratios lead to higher rebar strain rates but have no influence on crack-bridging stress.

Calculation theory and damage analysis on crack width of RC seismic-damaged columns

Shitao Cheng et al.

Summary: A new method based on the bond-slip theory is proposed to calculate the crack width accurately for seismic-damaged RC columns. This method can reveal the dynamic evolution process and failure mode of crack width, providing strong support for rapid assessment of seismic-damaged RC columns. The analysis of an example proves the accuracy and credibility of the new method in evaluating the damage degree of seismic-damaged RC columns.

Shear tests of GFRP-reinforced concrete beams strengthened in shear by textile reinforced concrete

Cao Thanh Ngoc Tran et al.

Summary: Shear tests were conducted on six GFRP reinforced concrete beams with aspect ratios ranging from 2.3 to 2.8 to investigate the effectiveness of using textile reinforced concrete in shear strengthening. The results showed that textile reinforced concrete was capable of enhancing the shear strengths of beams with different aspect ratios, and increasing the number of fibre layers in textile reinforced concrete was effective in improving both shear strengths and post-elastic stiffness of the beams.
