Design teams are increasingly looking at timber construction options for mid-rise buildings and are rapidly learning about timber-based system optimisation and specification. One of the most important professional groups to timber’s success in a project is the structural engineer. The Mid-rise Timber Building Structural Engineering Design Guide aims to provide the latest state-of-the-art design information for structural engineers to allow them to confidently undertake a mid-rise timber building design. This design guide is split into two parts: ? The front sections provide an overview of the typical structural design process for a mid-rise timber building. More detailed explanations, considerations and assumptions are provided for specific structural element design. ? The back section provides two appendices illustrating the design process for the major structural building elements. Included in this version of the design guide are: – Appendix 1: Worked Example for a Timber-framed Apartment Building – Appendix 2: Worked Example for a CLT Mass Timber Apartment Building.
