THE APPLICATION OF L-SHAPED CONCRTE STRUCTURE IN THE DESIGNS

A solution to the problem of beams used in stairs,which appear in civil engineering designs frequently.The difference between thin\|walled structure and command rectangle beam under actual load has been manifested.Analysis of the thin\|walled member in the conditions of bending,shearing and torsion stress and the calculation of the control factors under vertical load have been worked out.Through all these analysises above the methods of calculation and reinforcement for the member have been derived.
