Abstract: In spite of recent development in earthquake resistant engineering, earthquake still inflict widespread damage at various parts of the world. The importance of space structures to survive earthquake have been noticed from the experience of severe earthquakes. At present various measures against the earthquakes are applied to the space structure. Non-linear Static analysis has been widely used on earthquake response prediction of building structures under severe earthquakes. It needs to be studied whether it is applicable for reinforced concrete Cylindrical Shell structures or not. In this paper, Non-linear Static analysis of Multi-bay Cylindrical Shell structures is introduced. The first mode lateral loading pattern for the Multi-bay Cylindrical Shell structure with nine other cases is adopted to perform the pushover analysis. The Non-linear Static analyses results are compared with linear static, linear dynamic and non-linear time history analyses results. All the analyses were performed using SAP2000.
