Abstract

In both precast and in situ construction, short, randomly oriented fiber reinforcements in concrete and cement matrices are gaining popularity. Currently, load-bearing structural components are made of steel, polypropylene, and glass fibers, but the focus is turning to organic and natural fibers for macro-reinforcement in cement and concrete matrices. Indian scientists started studying composite fiber-reinforced concrete in the 1970s. Reactive Powder Concrete, or RPC as its acronym is known, is a kind of “Ultra High-Performance Concrete” (UHPC). The main ingredients of RPC are cement, sand, silica fume, steel fiber, and quartz powder, and the water-to-binder ratio is maintained as low as feasible. This material does not include coarse aggregate. It is possible to substitute RC flat slabs and steel tube columns filled with concrete for the traditional high-rise building constructions (CFST). The effectiveness of the structural type depends on the link between the CFST column and the RC slab. This work led to the development of a special shear-head A link’s design for reinforced concrete flat slabs and steel tube columns has been presented. To ascertain the strength and endurance of the relationship, two thorough examinations were conducted. To confirm the accuracy of the measurements, ABACUS used the finite-element approach. Based on experimental and numerical data, the punched shear capacity of a flat slab may be estimated analytically.
