Abstract
As height of building increases its displacement, story drift and story shear of the building increases abruptly. So, in order to restrain those parameters in the building especially under lateral loading, suitable methods are to be taken. In present tall buildings, those forces are often resisted by a system of Belt Truss. Belt truss is defined as the truss provided to the peripheral column of the structure around the core at particular height of the building, in order to provide sufficient firmness and strength against lateral loads. The paper aims to study the dynamic response of regular and torsionally irregular buildings of various shapes with belt truss by Response Spectrum Method. Also investigates the most effective shape of belt truss among X and V in reducing storey drift and storey displacement on different shapes of building. The parameters considered in the study are storey displacement, storey drift and stiffness of the buildings. Results show that belt truss reduces storey drift and storey displacement and increases storey stiffness of regular and irregular buildings. It is more effective in irregular buildings compared to regular buildings.
