2013-8-8The finite element method is commonly used to design the reinforcement in concrete slabs. In order to simplify the analysis and to be able to use the superposition principle for evaluating the effect of load combinations linear analysis is generally adopted even though concrete slabs normally have a pronounced non-linear response

The results obtained with this method were promising especially for research purposes since it generated reliable data using relatively affordable tools.The use of FRP for shear strengthening introduces further complications to the problem of shear in reinforced concrete members because introduces two new failure modes debonding at the
The safest approach is to remove the topsoil and place a minimum 4-inch layer of compactible gravel or crushed stone as a base over the undisturbed subsoil. Use unwashed material that has a top sie of 114 inches and includes smaller sies right down to the fines the irregular shapes and sies interlock nicely when compacted. Gravel or stone
