Evaluation of the connection rigidity on the vertical shear distribution at beam section in steel I shaped beams according to the beam span length

This paper evaluates the effect of I-shaped beams connection rigidity with different span length on vertical force and shear stress distribution in beam flanges and web at connection section in comparison with classical theory of stress distribution. Accordingly, 72 models with different connection...
