STRUCTURAL PERFORMANCE OF PRECAST CONCRETE BEAM-COLUMN JOINTS USING DFRCC IN PANEL

Performance 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 ...

performance of exterior precast concrete beam-column dowel connections under cyclic loading

the present study focuses on the performance of precast concrete beam-column dowel connections subjected to cyclic loading by conducting experiments. in this study, one-third scale model of two types of precast and a monolithic beam-column connection were cast and tested under reverse cyclic loading. the precast connections considered for this study is a beam-column connection where beam is con...

AN OPTIMIZATION PROCEDURE FOR CONCRETE BEAM-COLUMN JOINTS STRENGTHENED WITH FRP

This paper illustrates an optimization procedure of concrete beam-column joints subjected to shear that are strengthened with fiber reinforced polymer (FRP). For this aim, five different values have been considered for length, width and thickness of the FRP sheets which created 125 different models to strengthen of concrete beam-column joints. However, by using response surface methodology (RSM...

Seismic Behavior of Beam Column Joints in Reinforced Concrete Moment Resisting Frames

Strengthening of defected beam–column joints using CFRP

This paper presents an experimental study for the structural performance of reinforced concrete (RC) exterior beam-column joints rehabilitated using carbon-fiber-reinforced polymer (CFRP). The present experimental program consists of testing 10 half-scale specimens divided into three groups covering three possible defects in addition to an adequately detailed control specimen. The considered de...
