Innovation and efficiency combine in a solution for mass timber steel connection design by Cast Connex. Their use of Altair® HyperMesh® and Altair® OptiStruct® to predict the stresses in an architecturally exposed timber-steel connection helped them simulate the tight tolerances required for a sliding assembly and enable flat packaging for efficient transport. Simulating the cantilevered connection arm's deformations under expected loading conditions ensured the connection performed well for structural strength and serviceability.
