The current scenario of high-rise buildings have different shape of configuration along the plan and height. Such buildings are prone to lateral loads such as earthquake or wind. These buildings under the effect of earthquake show displacements and torsional behaviour. The modes of vibrations of building also depends on the torsional, stiffness, mass and drift of such buildings. Storey drifts corresponds to the natural time period of the building and the acceleration came from the earthquake. The buildings should be restricted to the provision given by the analysis and design codes of the country. To minimise the effect of earthquake many methods have been adopted. Shape of the building is also one of the such approach. This paper is a review on the effect of shape on earthquake by various researchers and engineers. The paper consists of short review on the test computer model analysis and the software results by the different models.
