ABSTRACT
This research introduces the Integrated Timber Core (ITC) system for high-rise timber buildings. The core runs full height of the building, acting as a cantilever to resist lateral loads. The ITC is composed of core columns and core beams that are made up of CLT panels that have been fabricated using LVL.
Current timber high- rise CLT buildings use ‘stacked’ panels, require multiple close spaced internal walls, and are cost effective to around ten levels. The ITC system has many advantages. It requires considerably less timber, has open space around the core for commercial use, and can be built to at least twenty levels (Wang 2019).
Successful laboratory tests for the ‘castellated’ core corner joints for a twenty level building are presented in this paper. The core corners, being well integrated together, means the core acts like a large full-building height square tube which is a very strong and stiff shape.
