The Shear Strength of T-shaped Broad-Limb Special Column Using the Finite Element Method

The T-shaped broad-limb special column is analyzed using the finite element method through the rational choice of calculated parameters and the results is compared with that of the experiment, and the two results is in good agreement which verify the calculation model’s correctness. Based on the correct model, the curve between the shear strength and the loading angles is analyzed and the column torsional effects is investigated when the column is loaded on different horizontal loading angles. The results show that, the relationship curve between the shear strength and the loading angles of T-shaped broad-limb special columns is approximately a rounded rectangle and the maximum shear strength are obtained when the loading angles is 60 ° and 240 °, and the torsional effect in the column body is considerably smaller.
