Hybrid Steel-Wood Mid-Rise Buildings

1. My Work Plan Carla Dickof Hybrid Steel-Wood Mid-Rise Buildings

2. Literature Review • I have reviewed the literature review done within our group • I am currently reviewing further case studies as well as research into the individual material types

3. Catalogue of Materials – Wood Floors • Wood floor system • Typical Joists and Sheathing • Stressed skin panels • Crosslam The floor system will be governed by the gravity of the loads except potentially at the roof. Commercial spaces with long floor spans will likely require crosslaminated floors. although the connections are more complex.

4. Wood Floors (cont.) • We should also look at occupation vibrations of the floors. This will be a much larger issue than it would be for typical concrete floors because of the large decrease in mass

5. Connections – Wood Floors • The connections for wood floors to the edge beams is important as these will be acting as the chords

6. Catalogue of Material – Wood Walls • Shear Wall Types • standard shear wall • Midply shear wall • Crosslam In the interested of having a centered wall we are likely better off to use a midply of double sheathed shear wall. As the connection forces are the hardest to obtain, likely a midply will be our best option

7. Wood Walls (cont) • For lower levels where connections become untenable for midply walls, we can consider the possibility of connections using solid crosslam • 8 story wood building in australia using crosslam floors and structural walls

8. Connections – Wood Walls • What connections can be used to deal with the overturning forces if we use wood shear walls • Can we design the overturning from above floors to be transferred into the steel frame

9. My Thesis - Ideas • Shear wall connections design and/or testing • Shear • Overturning • Shear diaphragm connections design and/or testing • Transfer for building irregularities • Connection to chords
