Structures require a complete load path to maintain stability. Load paths connect each point of load application to a point of resistance. In seismic design, every element with mass is considered a point of application and the foundation is considered the point of resistance. This presentation focuses on seismic load path and the role of diaphragms and their components, including chords, collectors, and collector connections. Foundation issues are discussed and the concept of deformation compatibility of the entire structure is presented.
