This text provides a single-source reference for parking structure designers, builders, and owners. It addresses how to select the best functional and structural designs for a given situation, ensure long-term durability, design for easy maintenance, decide on the number and placement of entrances and exits, design an easily understood wayfinding system, design for ADA compliance, plan for internal auto and pedestrian traffic circulation, select the most effective and energy efficient lighting system, avoid the most common design and construction pitfalls, provide for adequate patron safety and security, carry out needed repairs, and extend the parking structure life. Parking Structures addresses all the major issues related to parking garages. It should be an essential reference for parking structure owners, structural engineers, architects, contractors, and other professionals. This third edition of Parking Structures includes material on metric dimensions and recommendations for functional design globally, new research on flow capacity and queuing at parking entry/exits, an entirely new chapter on planning for a new parking structure, including cost issues and alternatives to structure construction, pedestrian considerations, safety in parking facilities, plazas above parking structures, an expanded chapter on seismic design, seismic retrofit, life cycle cost analysis, and upgrades to existing structures.
