Review of Vibration Assessment Methods for Steel-Timber Composite Floors
Publisher: MDPI AG
Date: 24-11-2022
DOI: 10.3390/BUILDINGS12122061
Abstract: Human comfort is recognized as an essential serviceability requirement for timber floors. Although several standards and design criteria are available for designing steel and concrete floors, there is no consensus among researchers on the applicability of such design methods to timber composite floors. Adding steel to timber floors is intended to create long spans, however, vibration is still a major challenge in achieving longer spans. To highlight the extent of this issue, a comprehensive search in the literature was conducted. The most common vibration criteria that may be used to assess the performance of steel-timber composite floors under human-induced vibrations were reviewed. For lightweight composite floors, the 1 kN deflection limit was found to be the most suitable vibration limit based on a wide range of subjective evaluation studies. For composite floors comprising steel and heavier timber subfloors, the relevance of 1 kN deflection criterion and other criteria suggested in the literature are questionable due to the lack of subjective evaluation studies. In the advent of advanced computing and data analysis, conducting detailed numerical analysis validated by accurate on-site measurements is recommended. Special attentions should be given to accurate estimation of connection stiffness and d ing ratio according to the findings of this study.
Influence of Weathering on the Structural Performance of Sheathing-to-Timber Connections
Publisher: MDPI AG
Date: 03-04-2023
DOI: 10.3390/F14040734
Abstract: The sheathing-to-timber connection (STC) is a critical component of timber-framed shear walls. The STC provides the shear wall system with its racking resistance, while anchors and tiedowns provide resistance to sliding and overturning, respectively. Because building materials are exposed to weathering during construction, this study aims to quantify the influence of weathering on the structural performance of STCs. To achieve this aim, a total of 117 small-scale specimens were fabricated with 5 different sheathing types and 2 different timber species. Each specimen comprised 2 panels of sheathing connected to 2 short lengths of pine timber (90×35 mm cross-section), with a total of 16/2.8ϕ×30 mm (l) galvanised clouts at 45 mm spacings. Some specimens were tested under the EN 594 monotonic loading protocol and others were tested under the ISO 16670 cyclic loading protocol. Some specimens were exposed to the weather for a period of 6 months before being tested, while others were stored in an air-conditioned environment before being tested. The results show that weathering reduces the ultimate and yield capacity of STC connections by 3% and 5% on average, respectively however, this result is not statistically significant for most sheathing types. The results varied, with some configurations having an ultimate capacity up to 16% higher and others having an ultimate capacity as much as 20% lower for weathered specimens compared to unweathered specimens. However, weathering reduces the stiffness of STCs by 61% and ductility by 50%, a statistically significant result. For most sheathing types, these findings do not support reductions to the design capacity of STCs that have been exposed to weathering.

Numerical modelling of timber/timber–concrete composite frames with ductile jointed connection
Publisher: SAGE Publications
Date: 27-01-2016
Abstract: Due to the scarcity of experimental data, this article focuses on the application of detailed finite element models for evaluating structural behaviour of timber–concrete composite frames with post-tensioned beam-to-column joints. In the developed finite element models, nonlinear behaviour and failure mode of timber and concrete under biaxial stress state are captured by hypo-elastic constitutive laws based on the equivalent uniaxial strain concept. In addition to material nonlinearities, the effect of geometrical nonlinearities and nonlinearity of contacts at the concrete slab-to-beam, beam-to-column and slab-to-column interfaces are considered in the finite element models. The accuracy of developed finite element models is verified against available experimental data on post-tensioned timber frames, and the validated analytical tool is used to undertake a parametric study. It is shown that elastic modulus of timber and the details of concrete slab-to-column connection can significantly affect the drift response and failure mode, whereas the compressive strength of timber and stiffness of timber–concrete composite connection have only a minor influence on the drift and failure mode of the timber/timber–concrete composite frames with ductile jointed connections.

Nonlinear long-term analysis of timber-concrete composite structures with finite element-finite difference scheme
Publisher: Trans Tech Publications, Ltd.
Date: 05-2014
DOI: 10.4028/WWW.SCIENTIFIC.NET/AMM.553.618
Abstract: Long-term analysis of timber-concrete composite (TCC) structures is a challenging task owing to the time-dependent behaviour of timber, concrete and connections which are highly nonlinear under variable environmental conditions (i.e. temperature, humidity). In this paper an efficient numerical method that takes advantage of a finite element-finite difference (FE-FD) scheme is presented. The differential equations governing the long-term behaviour of TCC section under variable humidity are solved using the FD scheme and the differential equations governing the mechanical behaviour of the composite beam are solved by a FE formulation recast in the framework of force-interpolation concept. The comparison between experimental data and numerical results shows the sufficient accuracy of the proposed FE-FD model for capturing long-term behaviour of TCC members.

Experimental Investigations of Material Properties of Timber Utility Poles Using Various Material Testing Approaches
Publisher: Trans Tech Publications, Ltd.
Date: 09-2013
DOI: 10.4028/WWW.SCIENTIFIC.NET/AMR.778.265
Abstract: This paper presents an investigation of using different material testing approaches to determine material properties of timber utility poles from two hardwood tree species, i.e. Spotted Gum and Tallowwood. The material properties investigated are the Modulus of Electricity (MOE), the Modulus of Rupture (MOR) and the compression strength (CS) in longitudinal direction as well as radial and tangential directions of the cross section of the poles. These material properties are needed for the accurate modelling of timber poles using Finite Element Method (FEM) for the study of stress wave propagation and damage detection in timber utility poles. In open literatures, for most timber species such comprehensive material property data are scarce to find. Typically, material properties available are only in the longitudinal direction. Furthermore, most international standards cover only details on material testing in longitudinal direction and no coherent nor comprehensive guidelines are given for the testing of the full orthotropic material properties of timber. Hence, an extensive study is deemed necessary to investigate a suitable approach to determine full material properties of timber. Two hardwood timber species, namely Spotted Gum and Tallowwood are selected for this investigation. Beside full material properties, the investigation is extended to examine different material testing approaches (bending, compression and tension testing) for the determination of the same material properties. The presented material testing is conducted on numerous small clear specimens as well as on four full scale 5 m long timber pole specimens of the two mentioned hardwood tree species.

Structural Response of Timber-Concrete Composite Beams Predicted by Finite Element Models and Manual Calculations
Publisher: SAGE Publications
Date: 11-2014
DOI: 10.1260/1369-4332.17.11.1601
Abstract: This paper presents the structural response of timber-concrete composite (TCC) beams predicted by finite element models (i.e. continuum-based and 1D frame) and manual calculations. Details of constitutive laws adopted for modelling timber and concrete are provided and application of the Hashin damage model in conjunction with continuum-based FE for capturing failure of timber under bi-axial stress state is discussed. A simplified strategy for modelling the TCC connection is proposed in which the connection is modelled by a nonlinear spring and the full load-slip behaviour of each TCC connection is expressed with a formula that can be directly implemented in the general purpose FE codes and used for nonlinear analysis of TCC beams. The developed FE models are verified by ex les taken from the literature. Furthermore, the load-displacement response and ultimate loading capacity of the TCC beams are determined according to Eurocode 5 method and compared with FE model predictions.
