FTAO Shear Wall Design: Updated Resources and a Project Application

Join this session to hear about recent updates to a Force Transfer Around Openings (FTAO) shear wall design resource, as well as a project example where FTAO design solved multiple challenges. APA’s FTAO Calculator is an Excel-based tool that can help engineers and code officials in the design implementation of FTAO shear walls, with a focus on asymmetric piers and multiple openings. This session will provide a brief overview of the tool and recent updates. The EOR of Las Ventanas, a five-story mixed-use project in Long Beach, CA, will then put this design methodology in context. The project includes a plethora of windows on its façade, and the strategic use of FTAO enabled a drastic reduction in hold downs while still achieving the levels of natural light called for in the architectural plans.
