Effect of Concrete Strength on Shear Capacity of Reinforced High-Strength Concrete Continuous Beams without Web Reinforcements

Shear Strength of Slender Reinforced Concrete Beams without Web Reinforcement

This paper attempt to predict the shear strength of high strength concrete beam with different shear span of depth ratio without web reinforcement. The large data base available has been clustered and a linear equation analysis has been performed . The prepared models are functions of compressive strength , percentage of flexural reinforcement and depth of beam. The proposed models have been va...

Scale Effect on the Shear Strength of Reinforced Concrete Columns with Termination of Main Reinforcements

A number of RC bridge columns which are similar with the columns which suffered extensive damage during the 1995 Kobe, Japan earthquake due to premature shear failure resulting from the termination of longitudinal reinforcements with insufficient development and the lack of shear reinforcements still exist. To improve the seismic performance, some of them were retrofitted. Evaluation of shear s...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
