1 Presentation 16: WALL TYPE IDENTIFICATION

2 Walls versus Partitions Walls –A general term for a vertical building component used to support loads and divide up living spaces –Also a term used exclusively to describe exterior vertical surfaces Partitions –Interior walls

3 Types of Walls Partitions and walls may each be load- bearing (LB) or non-load-bearing (NLB). With these combinations, there are four possible types of walls and partitions.

4 Types of Walls LBW NLBW LBP NLBP –Load-Bearing Wall –Non-Load-Bearing Wall –Load-Bearing Partition –Non-Load-Bearing Partition They are often built in this order.

5 Virtual Construction A portion of a typically framed house.

6 Virtual Construction Construction begins on a floor system.

8 These are exterior, thus they are walls.

9 Virtual Construction They are also load-bearing. LBW

10 Virtual Construction LBW

11 Virtual Construction This wall is exterior, but is not load-bearing. NLBW LBW

12 Virtual Construction This is an interior wall (partition) and can be load-bearing. LBP NLBW LBW

13 Virtual Construction The others are interior and non-load-bearing. NLBP LBP NLBW LBW

21 (4) NLBP Plate OC Dimension to Centerline NLBP LBW Note that centerlines are not from end of plate, but OC may be.

22 Conclusions Walls are exterior, partitions are interior. Each may be load-bearing or non-load-bearing. Layout of centerlines and OC studs varies.
