This on-demand webcast seminar has been developed to improve designer knowledge and confidence in the correct application of loading codes and appropriate design of industrial/commercial buildings consisting of both hot rolled steel and light gauge cold-formed steel (hybrid construction).
Particular focus will be applied to how both hot rolled steel sections and cold-formed steel sections can be effectively combined to optimize the structural design and reduce overall building costs.
Details will be provided on how to effectively design bracing, a key structural component that has previously failed in high wind events.
This webcast is essential for those who wish to remove the stress of designing these wind sensitive structures. If you are an engineer, a builder, or a certifier, you need to come along, inform yourself and be part of the journey towards more efficient outcomes.
