dc.description.abstract Reinforced concrete haunched beams (RCHBs) are widely used in structural applications such as bridges, mid-rise buildings, and portal frames due to their ability to efficiently resist high shear forces while offering reduced material usage. However, the variation in cross-section along the length of RCHBs presents unique challenges, particularly in assessing their shear capacity. This study numerically investigates the shear behavior of RCHBs under various loading conditions and compares them with prismatic beams. Moreover, parameters such as RCHBs with different haunch angles, reinforcement configurations, and shear spans were also thoroughly investigated. The analysis focuses on determining the effect of the vertical component of inclined forces on shear resistance and how the geometry of RCHBs influences shear behavior. Results show that shear capacity is significantly affected by haunch angle, with larger haunch angles leading to reduced shear capacity due to increased vertical force components. The findings also reveal that traditional shear design methods for prismatic beams tend to be conservative when applied to haunched beams. Recommendations are made for incorporating vertical force components into the shear capacity equation for more accurate design of RCHBs. The results align well with experimental data, providing insights that can enhance the structural safety and material efficiency of haunched beams in engineering practice. en_US
