| 摘要： | A finite-element (FE) model to simulate nonlinear structural behavior of posttensioned composite beams with partial shear connectors is introduced in this paper. Stress-strain material models for concrete and steel are implemented in the FE formulations and the nonlinear load-slip relation of shear connectors is also considered. With the load-slip relation, a nonlinear numerical formulation to consider the slip effect along the interface of posttensioned composite beams is derived. A solution procedure, which includes modeling of the section in prestressed concrete (PSC) structures, tendon behavior for consideration of sequential loading conditions, and a unique section analysis methodology to consider the partial shear connection of posttensioned composite beams, is also proposed. Numerical results yielded by the proposed model are compared with experimental results for verification of the model's performance. The results show satisfactory structural behavior of partially composite posttensioned beams, and thus the applicability of the proposed FE model is validated. |
