Summary
This PhD research provides a detailed procedure for designing and investigating the short term static behaviour of a proposed long span timber floor system for non-residential applications that meets serviceability and ultimate limit design criteria, with the use of timber as the only structural load bearing part of the system. In this study the behaviour of two types of LVL are investigated through a number of experimental and analytical tests. As a result of the tension and compression tests, a suitable constitutive law is developed which can accurately capture the stress-strain relationship and the failure behaviour of LVL, and it can also be incorporated into FE analysis of any LVL beam with similar structural features to the tested specimens. Further, the results of the full scale four point bending tests on LVL sections are used to identify the behaviour of LVL up to the failure point and to develop a finite element model to capture the behaviour and failure of LVL. Moreover, after investigating the long span timber floors, one system is proposed to be fabricated for the extensive experimental and numerical investigation. The results of the full scale experimental tests together with the numerical investigation provide a robust model for predicting the performance of any timber beams with similar structural features to the proposed system while the dimensions and spans can be varied according to special requirements such as dynamic performance or fire resistance requirements.

Summary
With the trend towards sustainable building design, timber-concrete composite floor systems attract great interest among building designers and developers as an alternative to the profiled steel-concrete deck that are commonly used in commercial construction. The proposed 2-layer composite floor deck consists of a profiled nail laminated timber (NLT) mainly designed in tension and concrete slab in compression. A numerical modelling approach was developed via commercial software ABAQUS to simulate the composite action of wood-concrete floors under four-point bending. The effects of NLT profile, thickness of concrete slab topping, fastening details, and shear span on composite action were analysed through a comparison of stress-strain development in both concrete and timber layers and the loaddeformation responses in shear connections of composite floors. Initial construction details of this composite floor system were therefore defined based on the preliminary analysis and will be examined further in the experimental phase of the project.
