There is no general consensus or accepted theory for evaluating the ultimate shear capacity of reinforced concrete beams without web reinforcement as a result the requirements in most of Codes of practice are provided in the form of empirical equatio

The shear strength of reinforced concrete members is a function of shear capacity of concrete (Vc), which in turn depends on influencing parameters including concrete compressive strength (f’c), ratio of tension reinforcement (), shear span to dept

In recent decades, use of fibre reinforced polymers (FRP) materials has become very popular for strengthening / re-strengthening of reinforced concrete (RC) structures. This includes flexural and shear strengthening of RC structural members such as s

This paper evaluates variations in the residual tensile strength of prismatic specimens made of steel fiber–reinforced high-strength concrete (SFRHSC) attributable to flexural cyclic loading. All specimens were previously subjected to a three-point

Used tires represent an increasingly serious environmental problem in the United States. This study examines the freeze-thaw durability of concrete with ground waste tire rubber. Various percentages of rubber, by weight of cement, were added to a con

The elastic behavior of mortar and concrete as a composite material and the influence of the transition zone on the elastic modulus is studied. The theoretical bounds of Hashin-Shtrikman for the modulus of elasticity of two-phase composite material a

A number of analytical models have been proposed for predicting the stress-strain curves of spirally confined concrete. In this Paper the analytical models available in the literature for confinement of concrete by circular spirals are studied, and t

A model for predicting the stress-strain relationship of circular spirally-confined concrete is presented. The model utilizes Boussinesq's approach to calculating the beneficial effect of hoop confinement on the strength of concrete. The lateral stre

This article presents an analytical model to predict the stress-strain relationship of spirally confined medium- and high-strength lightweight aggregate (LWA) concrete columns. The confinement pressure is assumed to vary along the height and the late
