In-Plane Performance of Unreinforced Concrete Masonry Strengthened with Prestressed GFRP BarsGlass fiber reinforced polymerMasonry wallsPrestressingStrengthening.This research investigates the feasibility of using prestressed glass fiber reinforced polymer (GFRP) bars for enhancing the in-plane shear strength of...
This paper presents an analytical model to predict the shear strength of reinforced concrete (RC) exterior beam-column joints without transverse reinforcement (denoted as unreinforced) in the joint region. Several existing analytical models developed for reinforced beam-column joints have shown limited su...

I usually assume a continuous wedge of concrete with a 70 degree angle to the vertical would fail in shear from the edge of bearing, and then calcuate the shear resistance of the failure surface, using the equation for concrete tensile stength of studs. (phi*Ao*2.8*L*Sqrt(fc')) - using...
Effect of confinement on the behaviour of high-strength lightweight concrete columns This paper summarizes an experimental investigation into the behaviour of high strength sand 鈥 lightweight concrete columns confined with rectangular ties. Fifteen reinforced and three unreinforced specimens were tested unde...

For shear strength, the diagonal masonry prism of 24 × 24 × 4.5 in. (60.9 × 60.9 × 11.4 cm) as per ASTM E 519 samples was made during the construction of the test specimen as shown in Figure 7(b). Samples of the concrete cylinder were collected at ...
Stitching ties can also be grouted into existing masonry joints to repair cracks and increase strength with minimum disturbance. (8) Concrete Foundation New foundation elements may have to be designed and built due to damage and/or inadequacy of existing foundation elements, or when they are ...
