Abstract

Designers are more interested in strength of structures at cracking rather than ultimate stage. Evaluation of torque and twist of high strength concrete distressed beams with “U” wrap made by ferrocement has been presented here. These parameters are evaluated by experimental and analytical method. The above two methods are not providing quick solutions, rather the first one is based on destruction of prototype structure for evaluation of strength. To overcome this, soft computing methods have been employed. Two methods MARS and WASPAS are employed here to compute the torsional strength of “U” wrapped beams. These two methods provide quick solutions to estimate the torque and twist at cracking. The predicted values by these methods are within the acceptable limits. The cracking torque is found to be increased by 40.94% when a ferrocement “U” wraps is provided without any reinforcement in the core. With reinforcement in the core, this value increased to 47.22% and twist also increased significantly. This proves the efficacy of ferrocement “U” wrap on outer periphery.
