Evaluation of Linear seismic behavior of space structures under different support conditions

Joints are necessary components in large space structures which have significant effects on the dynamic behavior of these joint-dominated structures. The accurate modeling of connection joints for civil engineering structures is challenging. This paper deals with the impact of joints on the dynamic response of space frames. This study assumed that the joints are either pinned or rigid. SAP۲۰۰۰ software was used to design and analyze the structure, and the behavior of this structure under seven different earthquake records has been investigated.
