| Abstract: |
| By using structural mechanics method, the stiffness matrix of reinforced concrete space bar with invariant reinforcement arrangement distribution along the bar has been derived; the nonlinear behavior of space bar member is described by the nonlinear behavior of several Gauss Quadratic place sections. For matching the space bar with variant reinforcement arrangement distribution along the bar, this type of space bar is divided into two or three segments with invariant reinforcement arrangement distribution along the bar, and its stiffness matrix is derived on the basis of the stiffness matrix of reinforced concrete space bar with invariant reinforcement arrangement distribution along the bar. Finally, the experimental results of model structure and the analytical results of a reinforced concrete space frame by using the convectional 3-D element model are used to compare with the analytical results by using the proposed model, It is shown that the proposed model and analysis method are applicable and feasibility. |
