EFFECTS OF STAIRCASE ON THE SEISMIC BEHAVIOR OF RC MOMENT FRAME BUILDINGS

Abstract Staircase has a potential to change the seismic behavior of structures, but it is often neglected during design. In this research, effects of staircase in 5 groups including 27 models have been studied. Results show that staircase constructed with the use of RC slab, performs as a K-shaped bracing in longitudinal direction and as an inclined shear wall in transverse direction, so in both directions structural stiffness increases, period and lateral displacement of structure decrease

STUDY ON THE INFLUENCE OF STIFFNESS OF BEAM–COLUMN CONNECTIONS ON THE SEISMIC BEHAVIOR OF COMPOSITE MOMENT RESISTING FRAMES

amplitude of lateral displacements and the modes of collapse are a function of the flexibility of the connections, especially in semi-rigid connections [14]. Therefore, it is necessary to study the influence of the semi-rigidity of the connections (composite beam to steel column) on the seismic behavior of composite frames. Generally, this inelastic seismic behavior is controlled by the response factor R [15]. In this context, this paper deals with the effect of the semi-rigidity of the composite beam
