Web Crushing Of Reinforced Concrete Structural Walls

Web crushing strengths of structural walls are predicted as a function of concrete strength axial load and lateral interstory drift.

Web crushing of reinforced concrete structural walls.

It is shown that web crushing strength depends on the level of applied deformations as well as the level of applied lateral and axial forces. 81 22 web crushing of reinforced concrete structural walls by r g. An analytical model based on truss analogy is used to evaluate the experimental results and to obtain a design equation that predicts web crushing strength. Corley results of an experimental investigation of isolated reinforced concrete structural walls subjected to inelastic load reversals are discussed and evaluated.

Both walls with conventional web reinforcement failed due to web crushing. The evaluation of dependable limits on the web crushing behavior of high strength con crete wall elements within the performance based framework will allow designers to achieve higher strength for less weight reduced material use and lower life cycle costs due to improved durability to adverse environmental effects this neesr ii 05 project has as a goal to establish acceptable limits on the elastic and inelastic shear strength of structural walls and structural wall assemblies. Web crushing strengths of structural. Walls subjected to significant inelastic deformations and with strengths limited by concrete crushing of the web after flexural yielding are considered in this paper.

Web crushing of reinforced concrete structural walls aci journal. Web crushing of reinforced concrete structural walls aci journal technical paper title no. This paper discusses the relationship between concrete strength and web crushing capacity based on results from large scale tests of thin webbed structural walls with confined boundary elements. Results of an experimental investigation of isolated reinforced concrete structural walls subjected to inelastic load reversals are discussed and evaluated.

A single layer of web reinforcement was used and the transverse reinforcement in the boundary elements did not confine the concrete core. An analytical model based on truss analogy is used to evaluate the experimental results and to obtain a design equation that predicts web crushing strength. This paper discusses the relationship between concrete strength and web crushing capacity based on results from large scale tests of thin webbed structural walls with confined boundary elements. Pinched shapes characterized the hysteresis curves for top displacement and shear distortion near the base.
