Numerical and experimental study on proposed T-form semi

This paper presents the results of experimental and numerical study on a proposed exterior semi-precast moment-resisting concrete connection. Steel linkage element connects precast concrete beam to column in two cases of bolted and welded connections. These connections were compared to monolithic connection based on stiffness, strength, energy dissipation capacity and ductility factor.

A new ductile moment-resisting connection for precast

A new ductile moment-resisting beam-column connection is developed for precast reinforced concrete (RC) frames in high seismic zones. The proposed connection provides good structural integrity in the connections and can reduce construction time by eliminating the need for formworks and welding, and minimizing cast-in-place concrete volume.

Advantages and Disadvantages of Reinforced Concrete

The maintenance cost of reinforced concrete is very low. In structures like footings, dams, piers etc. reinforced concrete is the most economical construction material. It acts like a rigid member with minimum deflection. As reinforced concrete can be molded to any shape required, it is widely used in precast structural components.
