Title: | Shear transfer in high strength concrete | Authors: | THAMARAIKKANNAN VINAYAGAM | Keywords: | shear transfer, pre-existing crack, high strength concrete, steel fiber, FRP, maximum shear reinforcement; minimum shear reinforcement; shear transfer | Issue Date: | 21-Sep-2005 | Citation: | THAMARAIKKANNAN VINAYAGAM (2005-09-21). Shear transfer in high strength concrete. ScholarBank@NUS Repository. | Abstract: | The shear transfer across cracks in using high strength concrete (HSC) with three different reinforcing materials is investigated both analytically and experimentally. High strength concrete is effective in improving shear transfer capacity when a higher amount of conventional steel reinforcement is used. Steel fiber inclusion to concrete enhances the shear transfer strength. Interaction of steel fiber and conventional reinforcement is more effective with high strength concrete and small amount of reinforcement quantity. FRP reinforcements are effective only up to a certain limit. With higher amount, FRP reinforcements are less effective compared to steel. FRP reinforcements have other disadvantages such as brittle failure and higher crack widths and shear displacements at ultimate stage. After a careful scrutiny of the available analytical methods, a new model for shear transfer across a discrete crack is proposed. Based on experimental results, ultimate shear transfer strength equations are proposed for various concrete strengths and reinforcing materials. Also the, minimum and maximum limit to the reinforcement parameter and the maximum ultimate shear transfer strength are obtained analytically. | URI: | http://scholarbank.nus.edu.sg/handle/10635/17041 |
