Outline

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

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?

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

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 building frame system
• Gravity loads ? Beams, Columns, Slab
• Lateral loads ? Masonry Shear Walls
• Butthe two systems still must work together

Keep in mind that the quality of construction at
the site is not typical of the surrounding area.

Non-engineered Structures

Construction Goals

• Construction of the 2nd Story Beams, Roof, and/or
  Chimney
• You need to select your column locations (the
  photos can serve as a guide)
• develop a detailed framing plan for the second
  floor and chapel roof, and
• determine loads for the entire structure.

58
You should have already

• selected
• material properties for concrete and steel
• and be well on your way to
• determining the design wind speed and seismic
  category for the site.
