A cold-formed, thin-walled steel/fast-growing timber composite system has recently been presented for low-rise buildings. It aims to increase the use of fast-growing wood as a green building material in structures, thus contributing to the transformation of traditional buildings. This study proposed a composite I-beam combined with fast-growing radiata pine and cold-formed thin-walled U-shaped steel. A four-point bending test was used to measure the bending properties of steel–timber composite I-beams under various connection methods. Based on experimental results, this study examined the specimen’s failure mechanism, mechanical properties, and strain development. In addition, a method for calculating flexural bearing capacity based on the superposition principle and transformed section method was suggested. It is evident from the results that fast-growing timber and cold-formed thin-walled steel can have significant composite effects. Different connecting methods significantly impact beams’ failure mode, stiffness, and bearing capacity. Furthermore, the theoretical method for calculating the flexural bearing capacity of composite beams differs from the test value by less than 10%. This paper’s research encourages the applications of fast-growing wood as light residential components, and it serves as a reference for the development, production, and engineering of steel–timber composite structural systems.

Nowadays life style practices demand more packed foods in the market around the world. In this trend increases the demand for researches on developing new packaging materials. In this research focuses novel AA8079/ SS304/ Wood ash hybrid nanocomposites development for meeting packaging related applications. The materials like aluminum alloy AA8079 (matrix material) obtained from waste food cans, Nanoparticles of stainless steel SS304 and Nanoparticles of Wood ash which obtained from waste bamboo woods were utilized to compose through stir casting process. Two set of Six different novel AA8079/ SS304/ Wood ash hybrid nanocomposites by varying the reinforcement from 0 wt.% to 10 wt.% with the step of 2 wt.% in the AA8079 matrix. The prepared composites included for examinations to test their Ultimate Tensile strength, yield strength, percentage of elongation, shear strength and hardness properties. Apart from this, the effect of heat treatment and annealing on strength of developed novel AA8079/ SS304/ Wood ash hybrid nanocomposites were investigated.

“…In recent years, wood has become an increasingly interesting alternative to steel and concrete due to greater environmental awareness and the general trend towards sustainable construction materials. There are many studies that have investigated different materials and manufacturing processes to develop highly engineered wood products to achieve an increased load-bearing capacity and stiffness [1][2][3][4][5][6]. Products made from biological materials such as wood often exhibit complex mechanical behaviour.…”

When wood is used as a structural material, the fact that it is a highly inhomogeneous material, which significantly affects its static and fatigue properties, presents a major challenge to engineers. In this paper, a novel approach to modelling the fatigue-life properties of wood is presented. In the model, the common inverse-power-law relationship between the structural amplitude loads and the corresponding number of load cycles to failure is augmented with the influence of the wood’s mass density, the loading direction and the processing lot. The model is based on the two-parametric conditional Weibull’s probability density function with a constant shape parameter and a scale parameter that is a function of the previously mentioned parameters. The proposed approach was validated using the example of experimental static and fatigue-strength data from spruce beams. It turned out that the newly presented model is capable of adequately replicating the spruce’s S-N curves with a scatter, despite the relatively scarce amount of experimental data, which came from different production lots that were loaded in different directions and had a significant variation in density. Based on the experimental data, the statistical model predicts that the lower density wood has better fatigue strength.
