Bridge Design

The Bridge Design project focuses on developing an innovative pretensioning method for steel truss bridges. The design concept aimed to increase the structural capacity while reducing overall weight, resulting in a higher specific strength. This optimisation not only improves load-carrying performance but also offers potential savings in material costs and sustainability impact.

The design underwent advanced computational modelling and simulation to validate its performance under various load cases, including dynamic, environmental, and live load scenarios. The results demonstrated a significant increase in efficiency compared to conventional truss systems. The proposed configuration is now undergoing review by multiple Australian contracting firms for ease of fabrication and labour cost considerations.

WYSE International’s Role

WYSE International provided structural design and high-fidelity finite element analysis to assess the performance of the novel pretensioned truss configuration. The work involved:

Developing conceptual and detailed 3D models of the truss system.
Performing nonlinear and high-resolution FEA simulations to study behaviour under service and ultimate loads.
Optimizing pretensioning parameters to balance performance gains with fabrication feasibility.
Coordinating design outputs in formats suitable for engineer’s review and potential prototyping.
