“…In order to improve mechanical resistance in pieces of wood, Corradi et al (2015) add CFRP to pieces of solid wood of Castañee Sativa, while Nadir et al (2016) did it with laminated wood of Hevea Brasiliensis. Reis et al (2018) recommend CFRP soaked bars to reinforce wood beams.…”

Wooden structure restorationwork in historical buildings requires substitution and/or reparation of structural elements. The aim of this investigation is to compare the density, wave velocity, dynamic module, and quality factor intest pieces of solid wood, laminated wood and a multimaterial of P. pseudostrobus. The work hypothesis proposes that dynamic modules of laminated wood and multimaterial laminated wood reinforced with stainless steel mesh are, at least, equal to solid wood. Small dimension test pieces made of solid wood, laminated wood, and multimaterial wood elaborated with the species P. pseudostrobus were prepared. Humidity content and apparent density of wood were determined. Ultrasound tests in radial, tangential, and longitudinal direction were doneand wave velocity, dynamic module, and quality factor were determined. Empiric evidence indicates that wave velocity, dynamic module, and quality factors are different with the three kinds of test pieces. Laminated wood and multimaterial wood characteristics are similar to P. pseudostrobus solid wood; so that the two compound material have good expectations to substitute some pieces that work as resistance elements in wooden structures.

“…Due to the high quality of its timber and their economic importance [10][11][12]. Consequently, the bamboo species have been found to have a lot of potential for the building sectors in the future because their derived products have more sustainability rates and are naturally renewable, recyclable, and reusable, [13]. One of these is forest products, and the increased demand for them will necessitate their expansion and exploitation with little waste and loss.…”

The fastest-growing plant on earth is bamboo; it grows three times as quickly as most other species and is a renewable, adaptable resource with high strength and lightweight. Bamboos are a valuable alternative resource with high physical similarities with genuine hardwoods. Using these naturally available renewable bamboo resources provides a practical approach to an eco-friendly industry mainly based on green materials and sustainable technologies with minimum impact on nature. In this regard, developing advanced bamboo-based composites is an attractive step. The extensive use of bamboo composites is a result of their advantageous qualities, including dimensional stability, natural colour, exquisite texture, and ease of manufacturing. The bamboo-based composites have immense potential to perform as a wood substitute that can reduce timber import and meet future timber requirements that are presently fulfilled by cutting trees or importing timber. This chapter aims to exhibit these advanced bamboo composites as a competitive and sustainable substitution for conventional timber material for structural applications. The present chapter highlights the advanced bamboo composites as engineered materials utilised mainly for structural applications in housing sectors and construction industries in the form of standard regular shapes such as beams, planks, lumbers, truss elements etc. One of the sections would be dedicated to the future scope of these advanced bamboo composites and recommendations.

Differential Evolution (DE) is an efficient and effective algorithm recently proposed for solving optimization problems. In this paper, an improved version of Differential Evolution algorithm, called iDE, is introduced to solve design optimization problems of composite laminated beams. The beams used in this research are Timoshenko beam models computed based on analytical formula. The iDE is formed by modifying the mutation and the selection step of the original algorithm. Particularly, individuals involved in mutation were chosen by Roulette wheel selection via acceptant stochastic instead of the random selection. Meanwhile, in selection phase, the elitist operator is used for the selection progress instead of basic selection in the optimization process of the original DE algorithm. The proposed method is then applied to solve two problems of lightweight design optimization of the Timoshenko laminated composite beam with discrete variables. Numerical results obtained have been compared with those of the references and proved the effectiveness and efficiency of the proposed method. Keywords: improved Differential Evolution algorithm; Timoshenko composite laminated beam; elitist operator; Roulette wheel selection; deterministic global optimization.
