Seismic Behavior of Prefabricated Column-Footing Connection
Results of an experimental investigation of the seismic performance of prefabricated column-footing connections are presented. Tests were conducted on six 1/4-scale prefabricated column specimens inserted into prefabricated footings in two Groups. Group-1 consisted of four specimens, which were tested under constant axial load and cyclic inelastic lateral displacements. The remaining two specim...
متن کاملEffect of column-foundation connection stiffness on seismic performance of rocking steel braced frame
Residual drifts after severe earthquakes interrupt serviceability of buildings. Retrofitting of such buildings is in many cases very difficult and consumes lots of time and money. Recently, there are some attempts to develop the seismic design procedures to not only satisfy life safety criteria but also lead to more economical buildings. One of these modern methods of improving seismic performa...
متن کاملSeismic behavior of drilled beam section in moment connections
Abstract: Reduced Beam Section (RBS) and Drilled Beam Section (DBS) are seismic moment resistant frame connections, introduced after 1994 Northridge earthquake. RBS connection has been tested under cyclic loading and showed acceptable performance. In this paper, seismic behavior of Drilled Beam Section (DBS) connection is studied numerically using finite element method. A drilled beam section ...
متن کاملPerformance of the Modified Precast Beam to Column Connection Placed on a Concrete Corbel
Precast concrete structures in Iran are generally designed as continuous columns with hinged beams, thereby making them simple frames. In this system in site show walls in two directions of buildings guaranteed lateral resisting system. However, in order to obtain a seismic resisting frame, the connection between beam and column should be moment resisting and ductile, allowing the formation of ...
متن کاملstudy on the effect of the first hole distance of beam flange from column face on the seismic behavior of drilled flange connection (dfc)
beam to column welded connection with radius cut on beam flange is known as rigid connection that provides acceptable ductility for special moment resisting frame (smrf). in order to decrease the cost of construction and to provide an easy-to-construct structure, the new method is available for reducing the beam section based on drilling on beam flange , known as drilled flange connection (dfc)...
