Abstract

The first role of a civil engineer is to perform design and analyze the structure before it is built. The structure should provide a safe and green environment to live in and should take up less cost. Corbel is one of the complex structural members where the load applied is eccentric. Corbels can carry heavy loads under the bridges and must be designed for buckling and vibration analysis. The main focus of this study is to perform the reinforced cement concrete corbel using Midas NFX® and perform the static, buckling and vibration analysis. The results show whether the structure is safe in buckling and vibration. The buckling mode shapes and vibration mode shapes were presented. The topology optimization had been performed to identify the areas which carry loading with minimizing compliance as objective function. The optimal distribution of the material shows a strut and tie model in the design domain.

Keywords
