Researches on Rational Reinforcement of Equi-Limb L-Shaped Reinforced Concrete Columns

A nonlinear analysis program for the capacity of L-shaped columns with numerical integral method is complied. Using the program, the Date of Mx-My curves under different axial compression ratios is obtained for five different reinforcement of equi-eimb L-shaped reinforced concrete columns.The maximum moments in various loading angles are analyzed, the cross-section’s ability to bear load influenced by different reinforcement is discussed, The rational reinforcement of equi-limb L-shaped reinforced concrete columns is derived. The date shows that the theoretical values and experimental results meet closely. Finally, Some suggestions in practice design for equi-limb L-shaped columns are given.
