Study on the Nonlinear Structural Behavior and the Efficiency of Reinforcement of RC Wall Panels Subject to Biaxial Inplane Forces |
| Abstract |
This paper is associated with the theoretical and experimental investigation on the nonlinear structural behavior of reinforced concrete wall panels under biaxial stresses.In the theoretical research analyses have been carried out piecewise linearly in four ranges of elastic, inelastic, fracture and strain softening by finite element procedure to calculate displacements, stress distributions and cracked portion of conctrete. The concrete nonlinearities are formulated based on the existing biaxial test results of concrete.Test pieces for the structural test of wall panels have been made with different orthogonal and diagonal steel ratios by the dimension of 90x60x6cm3, and lateral loads are applied incrementally under constant vertical load to observe the crack initiation and propagation, the vertical load effect on the aggregate interlocking action and reinforcement efficiencies.The data measured from the tests and the analyzed results show close agreements each other, by which the analysis method suggested in this paper has proved itself to be a useful analytic scheme for the reinforced wall panels subjected biaxial inplane forces. |
