Transcribed Image Text:

A doubly symmetrical I-section beam is reinforced by a flat plate attached to the upper flange as shown in Figure 2. If the resulting compound beam is subjected to a vertical shear load of 200 kN, determine the distribution of shear stress in the cross section of the beam. Calculate also the shear force per unit length of beam resisted by the shear connection between the plate and the flange of the I-section beam. 400 mm a b.
