A Review of Enhancing Performance and Sustainability of RC Shear Walls
September 24, 2023Abstract
Reinforced Concrete Shear walls are vertical components within a structure that are specifically engineered to counteract horizontal forces, such as those generated by wind or seismic activity. Their primary purpose is to enhance the stability and resilience of the building by redirecting these lateral forces to the foundation. This redirection effectively minimizes the building’s lateral movement during events like earthquakes or strong winds. Nowadays, building owners highly value the ability to ensure maintenance without incurring additional costs even in the face of major earthquakes. To achieve this, it’s crucial to reduce damage and maintain the reparability of structural elements. Multiple shear walls often bear heavy gravitational loads and remain susceptible to brittle breakdown due to shearing forces during lateral seismic loading. This susceptibility substantially increases the risk of a complete collapse of the entire shear wall system. The aim of this research paper is to comprehensively study and analyze various research endeavors concerning retrofitting methods employed to enhance the seismic resistance of new or pre-existing reinforced concrete (RC) shear. This analysis will include real-world case studies of examined structures. Moreover, this paper highlights the future potential and provides recommendations for effective retrofitting practices.
The Effect of Using Different Cross-Sectional Shapes of Steel on the Flexural Performance of Composite Reinforced Concrete Beams
September 2, 2023Abstract
Various types of structures can be constructed using reinforced concrete, including slabs, walls, beams, columns, foundations, frames, and more. The incorporation of structural steel and reinforcements in concrete enhances the strength and durability of structural elements while compensating for the tensile weaknesses in the concrete material. This study aimed to investigate the behavior of reinforced concrete beams utilizing structural steel of different shapes. Four types of concrete beams were prepared: a standard beam with normal reinforcement, and three composite beams, each featuring structural steel with different sectional shapes – T-section, I-section, and channel section. The consistent parameters included the cross-sectional area of the specimens, each measuring 100x150x450 mm, a steel reinforcement percentage of 2% of the total volume, and the compressive strength of the concrete. The conducted tests involved applying a concentrated load at the mid-span of each beam to examine the specimens’ behavior in terms of strength, flexural load capacity, deflection, crack patterns, and failure mode. The results of this study reveal that, given the same steel ratio, the load capacity of beams reinforced with structural steel of a channel shape has surpassed that of the other beams. Additionally, specimens with structural steel plates exhibited higher maximum deflections before failure compared to the beams with conventional reinforcement.
