A Study on the Nonlinear Behavior of Reinforced Concrete Wall Beams |
| Abstract |
In this study theoretical formulas are suggested for nonlinear finite element analysis of the structural behavior of wall beams which are widely used in high rise concrete buildings.To investigate the applicability and the reliability of the theoretical analysis, the results are compared with the measured values from structural tests wall beams subject to vertical loads.The concrete nonlinearities are reflected in the constitutive relation of plane stress by strength magnification factor following stress ratio and by reduction factor which is accounted for nonlinear material properties of concrete.Rectangular elements with eight-nodes are used for concrete structures and truss elements are adopted for reinforcing bars in finite element formulation. |
