Experimental investigation on the effect of nano-silica on reinforced concrete Beam-column connection subjected to Cyclic Loading.

Beam-column joints are crucial load transmission zones because they face concentrated forces from both the beams and the columns. High shear and axial stresses caused by these concentrated forces in the area of the joint may result in decreased joint strength. This article proposes a new beam-to-column connection developed for precast concrete-resisting frames.
