Summary
Depending on the severity, fire damage can compromise the structural integrity of wood structures such as buildings or residences. Fire damage of wood structures can incorporate several models that address (1) the type, cause, and spread of the fire, (2) the thermal gradients and fire-resistance ratings, and (3) the residual load capacity. The investigator should employ engineering judgment to identify those in-service members that are to be replaced, repaired, or can remain in-service as they are. Suchjudgment will likely be based on the visual inspection of damaged members, connections, and any protective membranes.

Summary
The next generation of heavy timber building systems is about to transform the design and construction of many buildings in Australia. Products that make up heavy timber construction include: Cross-laminated timber (CLT) Expan: post-stressed frames and box beams Glulam and LVL beams, planks and floor systems An engineered timber building product, CLT is widely used internationally, particularly in Europe. Although it is not currently widely used in Australia, the potential for its specification in dividing walls, floors and ceilings is increasingly evident, particularly for multi-storey residential buildings. These buildings have acoustic requirements, stipulated in Australia by the National Construction Code, Building Code of Australia (BCA) or by a relevant Local Government Authority. Previous acoustic research programs covering CLT have been conducted in Europe and North America. The applicability of this data to the Australian market is limited due to the design of the testing to address codes that are not relevant to Australia. The overseas test elements also often include construction materials that are not available or not in widespread use here.

Summary
The CLT Handbook provides vital “How to” information on CLT for the design and construction community, and is a great source of information for regulatory authorities, fire services and others. The CLT Handbook is also a good textbook for university level timber engineering courses. In summary, the Canadian CLT Handbook will remain the most comprehensive reference for sharing the latest technical information on North American CLT. The Canadian edition of the CLT Handbook, first published in 2011 under the Transformative Technologies Program of the Natural Resources Canada, played an imperative role in accelerating the use and acceptance of CLT in North America. Its introduction subsequently led to the publication of the US Edition. The Canadian Edition supported the early use of CLT products from Canadian manufacturers in many small to large projects across Canada and the US, and paved the way for CLT and other wood products to be used in new applications like tall and large buildings, and bridges. Since then, additional research has taken place globally and substantial regulatory changes have occurred enabling more wood to be used in construction. Those developments highlighted a need for the CLT Handbook to be updated. The 2019 Edition of the CLT Handbook, for example, augments the recently developed CLT provisions in CSA Standard in Engineering Design in Wood and it includes a design example of an 8-storey CLT building. It helps expand the knowledge base of the designers about CLT enabling them to develop alternative solutions for taller and larger buildings that are beyond the boundaries of the acceptable solutions in building codes.

Summary
Cross-Laminated Timber (CLT) is an engineered mass timber product manufactured by laminating dimension lumber in layers with alternating orientation using structural adhesives. It is intended for use under dry service conditions and is commonly used to build floors, roofs, and walls. Because prolonged wetting of wood may cause staining, mould, excessive dimensional change (sometimes enough to fail connectors), and even result in decay and loss of strength, construction moisture is an important consideration when building with CLT. This document aims to provide technical information to help architects, engineers, and builders assess the potential for wetting of CLT during building construction and identify appropriate actions to mitigate the risk.

Summary
This guide provides reference data and methodology advice for cost engineering activities directly and indirectly associated with the design, procurement and installation of wood structures in Australia, especially with reference to mid-rise buildings (four or more levels). There has been a rapid growth in the use of Engineered Wood Products (EWPs) across the property industry. Since the delivery of Australia’s first mid-rise contemporary wood building – Forté Living from Lendlease – structural wood products have been used to construct a variety of buildings across the country. This trend has been supported by amendments to the National Construction Code (NCC), which since 2016 has provided a Deemed-to-Satisfy (DtS) solution for timber construction to an effective height of 25 metres (from 2019 applicable to all building classes), and has been further backed by the WoodSolutions free advisory program in this field. While many detailed guides have been published on the design and maintenance of timber structures, there has been relatively little focus on the specifics of costing and ultimately building them. This guide has been prepared to address the specific cost-related knowledge and approach that needs to be considered throughout the development process, with respect to the Australian Cost Management Manual and other relevant publications. Written in conjunction with Rider Levett Bucknall, a leading independent organisation in cost management, quantity surveying, project management and advisory services, this guide has been divided into sections associated with the typical activities of a cost engineer. While each section is complete on its own, the reader will gain most benefit by considering them to be inter-related, and it is recommended that the document is read as a whole. This guide refers to projects that are based on either individual Wood Products or systems, or their combinations. Further information on the nature, performances and design of such products and systems can be found, with a comprehensive and comparison-based approach, in WoodSolutions Technical Design Guide #46 Wood Construction Systems. Other guides within the WoodSolutions library offer more detailed information specific to a given application.

Summary
As part of its research work on wood buildings, FPInnovations has recently launched a Design Guide for Timber-Concrete Composite Floors in Canada. This technique, far from being new, could prove to be a cost-competitive solution for floors with longer-span since the mechanical properties of the two materials act in complementarity. Timber-concrete systems consist of two distinct layers, a timber layer and a concrete layer (on top), joined together by shear connectors. The properties of both materials are then better exploited since tension forces from bending are mainly resisted by the timber, while compression forces from bending are resisted by the concrete. This guide, which contains numerous illustrations and formulas to help users better plan their projects, addresses many aspects of the design of timber-concrete composite floors, for example shear connection systems, ultimate limit state design, vibration and fire resistance of floors, and much more.

Summary
Timber concrete composite (TCC) floor systems are relatively new to Australia and satisfactory performance requires a rigorous design procedure addressing both ultimate and serviceability limit states. TCC structures have a degree of complexity, since they combine two materials that have very different mechanical properties and respond in different ways to their environment. In addition, most TCC structures exhibit partial (not full) composite action. There are several design procedures for TCC structures. Among these, the Eurocode 5 (EC5) procedure is relatively straightforward and has been successfully implemented in Europe. It uses a simplification for modelling the complex timber–concrete interaction known as the ‘Gamma coefficients’ method, which manipulates properties of the concrete member to predict the cross-section characteristics of the structure. This Guide presents a design procedure for TCC floor structures that is based on the Gamma method and AS 1720.1 Timber structures Part 1: Design methods. The Eurocode 5 approach has been adopted as the underlying basis for the design procedures presented in this document; modified to comply with current design codes and practices in Australia. It comprises normative parameters for the strength and safety (ultimate limit state) and informative guidelines for appearance, deflection limits and comfort of users (serviceability limit states). While the latter must be defined by designers to meet the specific functional requirements of the floor under consideration, it is recommended that the serviceability guidelines in this document should be adopted as a minimum standard for TCC floors. At the time of publication of this Guide, there is still uncertainty about some aspects of long-term deflection of TCC floors. As such, it is recommended that designers exercise caution when applying the design procedures contained in this document to floors exceeding 8 m in span, utilising the notched connections and crossed screws. This caveat restriction is due to a lack of research data at this stage to support the behaviour of floors and connections for spans exceeding 8 m. Some general considerations for manufacturing the notched connections are presented in this Guide.
