Composite Material Alternatives to Timber in the Construction of Wing Walls

The proposed research will focus on developing composite material components to replace current timber elements for wear surfaces of wings walls in the Washington State Department of Transportation (WSDOT) ferry terminal structures. To accomplish this goal the project will address the following specific objectives. (1) From a review of current designs, plans, and installations, discern relevant design parameters and failure mechanisms in existing systems. (2) Develop a range of potential material properties possible to use in the large beam applications. (3) Conduct a structural analysis of the current wing walls to develop load demands, energy dissipation, and failure mechanisms for selected structural elements. (4) Develop a laboratory-scale test configuration and program for evaluating potential components. (5) Produce and evaluate composite formulations for relevant mechanical properties including strength, stiffness, durability, and wear performance. (6) Select potential formulation and fully evaluate component performance using the developed test configuration. (7) Design cross-section configuration of proposed composite members and evaluate for cost.
