Case Study: Arup verifies the 1915 Çanakkale Bridge design with Oasys Software

Arup verifies the 1915 Çanakkale Bridge with Oasys Software using 2D shell models and diagonal reinforcement

Arup was tasked with providing design verification for both the permanent and temporary structures of the 1915 Çanakkale Bridge. Their challenge was to technically review design packages and verify their conformity with the project Design Basis for the world-record span suspension bridge. To accomplish this, Arup used Oasys Structural software, including Oasys GSA and Oasys AdSec.

Using detailed verification tools developed with Oasys GSA, Arup identified errors in the rebar design of the bridge's massive concrete caissons. The Oasys software enabled engineers to model the complex structures, assess load paths, and use the RC Slab Design postprocessor to determine reinforcement requirements. This analysis revealed in-plane shear failures, leading to a solution involving the strategic addition of diagonal reinforcement. The work by Arup and Oasys ensured the structural integrity of the foundation caissons for this landmark project.
