A variable cross-sectional beam is pinned from the point B by BD bar as shown. Flexural rigidity of AB and BC beams are 2El and El, respectively. If the axial rigidity of the BD bar is EA, Determine the reaction forces at the point A by using,

All two-force members of the loaded structure are of the same length. Member BCD is a rigid beam. Determine the forces in members BG and CG. The forces are positive if in tension, negative if in compression. A Answers: BG= CG = i i B G L L L E

TEXT:A planar construction is composed of two beam elements and two axial rods. These arejoined with frictionless joints, as indicated on the sketch. The structure is applied an outer concentrated load P=8kN in node G and a downwardevenly distributed load q=4kN/m between junctions A and D. The beam ABCD and EFG are torque rigid,while the axial rods BF and CF only absorb forces in the direction of the rods. A) Calculate the rod forces and for the external given load effect.B) Calculate the bearing reactions for the external given load effect.
