Webb27 nov. 2024 · Optimization is the ultimate objective of engineers, through which they can design the most economical sections while having optimal performance. The ever-growing computational abilities and advent of improved optimization techniques have further eased its implementation. Despite these advancements, a review of literature has revealed that … Webb🕑 Reading time: 1 minute Shear design of reinforced concrete (RC) beam involves the determination of spacing between stirrups. Shear is a word used for forces that work perpendicular to the longitudinal axis of RC beam. Commonly, shear forces are maximum at supports of beams and decrease towards the middle of the beam span. RC […]
