| Résumé | An innovative solution to safely bridge very long spans is proposed in this paper by introducing a hybrid type cable stayed bridge as a competent system. The new system leads to huge reduction in deck weight and critical stresses in the pylon zones by using a hybrid advanced composite deck. It also reduces the stiffness losses of the stay-cables due to the catenary action by using carbon fiber reinforced polymer (CFRP) cables. The paper proposes a consistent and systematic analysis and design procedure (ADP) that optimizes and precisely simulates the proposed bridge system. It recognizes the changes in structural behavior of the cable-stayed system, and accordingly clearly defines the ultimate and serviceability limit states for such a new structural system, consistent with limit state design philosophy. The design steps of the ADP represent a multi scale design approach, while the analysis steps characterize a multi-scale modeling technique. They represent material design at the micro/macro-level, and accurate homogenization of the advanced composite components properties and evaluation of the resulting anisotropic characteristics. The method provides three dimensional simulation of the hybrid bridge system, involving all its nonlinearities. |
