Nonlinear Analysis Model of Fiber Plasterboard filled with reinforced concrete

摘要：

According to the material characteristic of fiber plasterboard filled with reinforced concrete, the computational macro-model basing on the multi-component element is proposed and stiffness matrix of the model is provided. The inner vertical springs of the model are located at the points of Gaussian integration to improve the computational accuracy and efficiency. Based on the experiment study, hysteretic models of the vertical and horizontal component are revised and revised skeleton curves of the components are given. The elasto-plastic push-over is carried out to the four fiber plasterboard filled with reinforced concrete with the macro-model. The computational results are close to those of experiments, which show that the model has relatively high accuracy and simple calculation. We can get some points that plasterboard and steel reinforcement greatly affect the strength performance of the board and that effect of the intensity of concrete is small.
