Structural Design of Industrial Buildings

The efficient structural design of industrial facilities requires engineers to understand the issues that can affect stability, safety, and serviceability. This course covers the structural design of industrial facilities in a systematic manner, starting with loads, load combinations, and different types of structural systems and framing concepts. The course then introduces roof-framing design including cantilever (Gerber) girders and open web steel joists. Participants will also study the detailed design of composite concrete-steel floor systems, focusing on vibration problems due to resonance, human comfort, and the need to control movement for sensitive equipment.
