Structural and Civil Engineering Curriculum
Module from the Structural and Civil Engineering Curriculum curriculum.
Module 8 - Equipment Foundations · Learning Objectives · 1. Size pump foundations: block weight 3-5x equipment weight · 2. Apply PIP STE03350 for static and dynamic equipment · 3. Design vibration foundations for rotating equipment (natural freq > 1.5x operating) · 4. Select anchor bolts: J-bolt, L-bolt, or headed per ACI 318 App D · 5. Specify grout: non-shrink epoxy or cementitious per API 686 · Equipment Foundation Types
