Complex building shapes and footprints are driving design procedures and code requirements to evolve for all lateral force-resisting systems and materials. Architecturally demanding exterior wall lines in modern structures do not always provide opportunities to use traditional design approaches. In mid-rise, multi-family buildings, corridor-only shear wall floor plans are becoming a popular design approach to address these issues. This paper summarizes a detailed design example of a single-story open front structure with a cantilever diaphragm following the requirements of ASCE 7-16, IBC 2018 and SDPWS 2015. A discussion of several design issues associated with these types of structures and the lessons learned from developing the example are presented.
