Methyl bromide (MB) has a number of desirable features as a fumigant for durable commodities and timber including a rapid speed of treatment, low infrastructure requirements, recognition by quarantine authorities, broad registration for use, good penetrant ability, and rapid airing after exposure. There is, however, a range of existing and potential alternatives to MB which, alone or in combina...

The present paper provides some ideas about how decisions concerning maintenance of timber bridges should be made in a rational way. First, a brief discussion is provided concerning the evolution of maintenance strategies in general and it is suggested that maintenance of timber bridges should follow a risk-based approach. Then the discussion moves on to the condition assessment of timber bridg...

Efforts to increase wood mobilization have highlighted the need to appraise drivers of short-run timber supply. The current study aims to shed further light on harvesting decisions of private forest owners, by investigating optimal harvesting under uncertainty, when timber revenues are invested on financial markets and uncertainty is mitigated by news releases. By distinguishing between aggrega...

The focus of this research is the stress laminated timber cellular deck. The testing program has involved application of loads that modelled both the design serviceability and design ultimate conditions, and identified slip and load redistribution mechanisms, which occur at the limit state of linear composite behaviour. This paper presents a summary of the results of this testing and discusses ...

Timber is a two player game played on a directed graph, with a domino on each arc. The direction of the arc indicates the direction in which the domino can be initially toppled. If one domino is toppled, it topples the dominoes in the direction it was toppled and creates a chain reaction. The goal of this game is to topple all the dominoes and the player who topples the last dominoes wins. A P ...

Managing and verifying forest products in a value chain is often reliant on easily manipulated document or digital tracking methods – Chain of Custody Systems. We aim to create a new means of tracking timber by developing a tamper proof digital system based on Blockchain technology. Blockchain will be combined with new digital protocols for physical verification and authentication. Deliverables...

A two-level Hierarchical Timber Allocation model was developed that iteratively negotiates medium-term (sustainable forest management) decisions with operational (lumber production) plans. At the medium-term level, a multi-criteria timber allocation model optimally allocates forest land units, called stewardship units, to different forest products companies based on five sustainability criteria...

The paper provides mathematical modelling for prefabricated timber-framed walls composed of a timber frame and two different types of sheathing boards. Since by wood-based boards (WBB) the tensile strength is similar to the compressive one, there are practically no cracks appearing in the boards. On the other hand, in case of fibre-plaster sheathing boards (FPB) the tensile strength is approxim...

The overall aim of our research is to eventually develop a viable system, using pinus radiata, for multi-storey timber buildings up to 6 storeys. One of the main issues is achieving sound resistant timber floors that are economically viable. This paper reports on the acoustic testing of a prototype floor, with radiata pole joists. Measurements were made of the objective performance. The results...
