Stiffness matrix for haunched members with including effect of transverse shear deformations

الملخص EN

This study includes the derivation of the stiffness matrix for a haunched member using the simple bending theory.

The derived stiffness matrix covers most possible geometric shapes for haunched members under different loading cases and combinations with including transverse shear deformations effect.ِ The importance of the transverse shear deformation in haunched members with high depth to span ratios is shown using numerical example.

The accuracy of the proposed analysis technique is verified by comparing the results of the numerical example with those obtained from the general analysis program SAP90 using a large number of subelements.
