Structural Engineering: Load Paths & Construction Considerations

Explore building systems and load paths, IBC requirements for concrete and masonry, and construction updates. Review how wind and altar loads reach columns, the impact of structure category, and coordination between gravity and lateral loads. References available for further study.

  1. CEE 4606 - Capstone IIStructural Engineering Lecture 4 - Load Paths and Construction Considerations

  2. Outline 1. Building systems 2. Load paths 3. IBC requirements for concrete and masonry 4. Construction update 5. Other projects

  3. General Comments • Schedules were fine for submittal, but need to have far more detail to be useful within your groups. • Load paths were good, but need more detail on the specific structural elements. 3. Answer these questions: • How does the wind load get to the column? • How does the altar load get to the column? • Are there any beams in your structure?

  4. Building Systems

  5. Load Paths • Building Frame System • Gravity loads are carried entirely by slabs, beams, columns (frame action) • Lateral loads are carried entirely by the shear walls

  6. Floor Slabs

  7. Elevated Slab(s)

  8. Wind Wind Load on Front Face

  9. Wind Wind Load from the side

  10. EQ Drawing 06 - Section Through Living Room

  11. IBC Requirements • How does having the Category (A – F) of the structure affect the design of the concrete structural elements (beams, columns, and slab) for gravity load? • How does it effect the design of the masonry walls?

  12. IBC Requirements • Remember that we have a buildingframe system • Gravity loads  Beams, Columns, Slab • Lateral loads  Masonry Shear Walls • But…the two systems still must work together

  13. References • Design of Low-Rise Concrete Buildings for Earthquake Forces, Portland Cement Association, 2nd Edition, 1998. • Reinforced Concrete, A Fundamental Approach, Nawy, 5th Edition, Chapter 16 • IBC, 2000, Chapter 19, Concrete • IBC, 2000, Chapter 21, Masonry
