dc.description.abstract | A beam-column joint is a critical region which contribute to the integrity of the structure and that transfer forces from one structural element to another. A beam- column joint need proper design and detailing to achieve adequate performance of reinforced concrete frame or else it causes large story drift and structural damage. Among the most common failure modes in beam-column joints, a shear-type of failure is the most sensitive to cause structural failure. When the joint is subjected to cyclic loading its shear strength will be affected by many factors such as concrete strength, column axial load, joint aspect ratio, transverse reinforcement and lateral beams. Predicting the joint shear behavior is difficult because of the combined effect of those different factors. Among those different factors, most researchers have different conclusion on the effect of column axial load on the joint shear strength, especially when the joint is designed and detailed according to capacity design philosophy. Therefore, this study mainly focused on the effect of column axial load on the shear strength of an exterior beam column joint; which is detailed according to capacity design philosophy. The effect of column axial load was studied through finite element software when the end of the beam was subjected to cyclic loading. The numerical study was performed through ABAQUS and the joint was examined with different magnitude of column axial loads and their effect on the shear strength of the joint was evaluated. The results obtained from the analysis showed that the column axial load up to 0.2f c ′ × A g provided confinement to the joint and enhanced the joint shear strength. On the other hand column axial load beyond 0.2f M.Sc. Thesis Page II c ′ × A g exhibited degradation of joint shear strength. This might be attributed to concrete, crushed in the joint region. | en_US |
