Behaviour of Reinforced Concrete Structure under Vibration Loading and Effect of Shear Reinforcement

Many of the complex behaviors of reinforced cement concrete under shear and flexure are yet to be identified to employ this material advantageously and economically. The progress in the understanding and quantitative assessment of the behavior of member subjected to flexure and shear has been less spectacular. The fundamental nature of shear and diagonal tension strength is not yet clearly understood. So, further basic research should be encountered to determine the mechanism, which results in shear failure of reinforced concrete members. The study presents the study of the behavior of reinforced concrete structure under seismic (vibration) loading and the effect of shear reinforcement. The influence of variation of web reinforcement spacing (both vertical and horizontal) on the shear strength of Grid slab is investigated. The general trend in crack pattern, the load deflection characteristics and the mode of failure of grid slab R.C. structure under two-points loading are also investigated. Through the investigation, it is observed that under two-points loading system, diagonal cracks are usually the first cracks to be observed in the clear span of the slab. In this study we will compare Grid slab with PT slab in G+10 structure using analysis tool ETABS.
