2. LVL STRUCTURES IN FLOORS, WALLS, ROOFS AND IN SPECIAL APPLICATIONS 2.5.5 Lift shafts of multi-storey buildings In wooden multi-storey buildings LVL-C panel structures can be used for lift shafts where they can also act as a part of the bracing system of the building. Panel sizes are suited for full building height or storey-high elements and the lifts structures can be installed to the shafts with conventional laterally loaded screw connections. 2.5.6 Extension of multi-storey buildings With the ever increasing population shift to urban areas, an interesting possibility for creating additional housing is to build extensions on the roofs of existing buildings. To achieve this, the new structures must be light enough so that the existing structures can carry the load. Robust, but light LVL structures provide the ideal solution. Figure 2.89.
