Analytical Investigation into the Effect of Axial Restraint on the Stiffness and Ductility of Diagonally Reinforced Concrete Coupling Beams

Bower, Owen J.

Abstract Details

2008, MS, University of Cincinnati, Engineering : Civil Engineering.
The effects of axial restraint on the stiffness and ductility of diagonally reinforced concrete coupling beams are investigated analytically through the use of finite element analysis. To provide accurate result without undue computational expense, a mesh sensitivity study is performed to determine the optimal mesh of the analysis. To validate the modeling technique, an analysis was performed reproducing experimental testing performed at the University of Cincinnati with good agreement between the two. An analysis was performed reproducing the experimental testing performed by Dr. Fortney at the University of Cincinnati. Finally, non-linear analysis of a prototype building utilizing the hysteretic response obtained from the finite element analysis for each case of axial restraint was performed. External axial restraint in diagonally reinforced concrete coupling beams is shown to increase the initial stiffness of the coupled core wall lateral force resisting system, as well as improve the post-peak stiffness and energy dissipation.
