Orbital Stack Rapid Wind Loading Analysis

Modern tower design has become increasingly complex as cities densify, as environmental pressures increase, and as designs push the limits in terms of height, complexity, and elegance. This has led to the need for more careful planning in the early stages of the design to ensure that those concepts can successfully be implemented later. However, tools to do this have been difficult to use or been unreliable.

In this workshop, we are going to get hands on with rapid, early-stage tools for structural and cladding design evaluation.

Your workshop host will briefly introduce the theory behind structural and cladding analysis and how different approaches fit into the design lifecycle for a typical building.

This will be followed by hands on work using Orbital Stack to explore the performance of real-world projects, discussing how to interpret and use these results for early-stage design guidance. An RWDI engineer will be part of the team and available to discuss design and mitigation options.

Participants are expected to bring one or two projects that they can work with during the workshop, evaluating cladding pressures for the project and optioneering various solutions to any problems that are identified. Participants can submit one design in advance for an Orbital Stack Tower Shaper (structural behaviour) evaluation. Workshop facilitator, John Kilpatrick, will be available to help evaluate and interpret results, and provide guidance and suggestions about massing and mitigation changes to try. Participants will be able to resubmit their structural design for a second run at the end of the workshop (with results available at a later time)
