“…CFRP (carbon fiber reinforced plastics) composite materials have been recently introduced as reinforcement elements. Efficient performance of CFRP reinforcement elements have been reported in several studies [1][2][3][4]. Due to severe shear stresses separation may occur between CFRP reinforcement element and the concrete which leads to less stress transfer from concrete to reinforcement and contrariwise.…”

“…However, it is noted again that only one specimen strengthened with CFRPs was tested and the strengthening layout of CFRPs used in this test was also newly developed. Meanwhile, in the studies by Realfonzo et al (2014) and Singh et al (2014), the beam-column joint specimens strengthened with various layouts of CFRPs were tested and the test results showed that the strength and ductility of beam-column joints could be increased up to approximately 72 and 98%. Further research is necessary for better understanding this behaviour.…”

Beam-column joints in existing concrete buildings might not satisfy the design requirements for seismic reinforcement details specified in current seismic design codes. Thus, in this study, various retrofit solutions for existing exterior beam-column joints with non-seismic details were developed: head re-bars anchoring, carbon fiber reinforced polymer (CFRP) wrapping, haunch retrofit element, and steel jacketing with various shapes and sizes. To investigate the seismic performance of exterior joints strengthened with the proposed retrofit solutions, seven half-scale exterior reinforced concrete beam-column joints including one control specimen and six retrofitted specimens were fabricated and tested under cyclic loading simulating earthquake loading. The test results showed that the proposed retrofit solutions could partially enhance the seismic capacity of the beam-column joints: steel jackets could increase deformation and load-carrying capacities; steel haunch elements could increase the load-carrying capacity, stiffness, and dissipated energy; and head re-bar anchoring and CFRP wrapping did not significantly effect on the seismic capacity of the beam-column joints.

Reinforced concrete is commonly used in any infrastructures. In building, it can be applied for beam and column separately, but the joints between those elements in this type of structure might be vulnerable due to the strength compared to the element itselft. In this study, some parameters namely ductility, stiffness, and energy dissipation of beam-column connection in precast concrete will be examined using finite element method. Six samples in this experiment are made considering some variations such as connection type in interior and exterios condition, round-shaped and rectanguler-shaped of column, and T-shaped and rectanguler-shaped of beam. Static loads were given in the middle of the beam and column so that the crack pattern can be obtained. From this experiment, it will be known the best and suitable joints by observing those three parmeters.
