Evaluation of Using Strong Column-Weak Beam Requirements in Prequalified Welded Connections in Intermediate Steel Moment Frame

Beams are genarally used to face bendind force and columns are used to face axial load. as the seismic load comes parallely with respect to earth surface. so the column faces the load pependicularly which is very risky for the column. after that load gets distributed to all the beams. for this reaso...
