“…Original bamboo culm has low rigidity and limited diameter. In order to solve these problems, industrial bamboo materials appeared in different forms such as parallel bamboo strand lumber (PBSL) [5][6][7][8][9][10], laminated bamboo lumber (LBL) [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] and so on. Laminated bamboo lumber (LBL) is made by laminating the thin flat bamboo strips together with adhesive under a certain treatment and the structural size could be controlled in the factory.…”

“…In order to apply laminated bamboo lumber to engineering area, many scientists [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] have done a lot of research on manufacturing technology and mechanical properties. Correal et al [12] studied the adhesive bond performance in glue line shear and bending for glued laminated guadua bamboo.…”

“…Varela et al [17] have investigated cyclic performance of glued laminated guadua bamboo-sheathed shear walls. Taheri et al [18] have studied buckling response of glue-laminated columns reinforced with fiberreinforced plastic sheets. Li et al [19][20][21] have studied the flexural performance of laminated bamboo lumber beam and the ultimate load calculation formula for the LBL beams were proposed.…”

Experimental study on laminated bamboo lumber column

et al. 2018

This paper presents and discusses the experimental study on the mechanical properties of LBL column both under axial and eccentric compression. The results shows that the ultimate load for the eccentric compression specimens with the eccentricity values of 30 mm and 110 mm are 95.2 kN and 31.8 kN respectively. Eccentricity is one of the main influencing factors for the ultimate bearing capacity of the LBL columns. Because of the vulnerability of the mechanical connections or natural nodes to tensile stress and secondly, laminated bamboo is vulnerable to defects that has more detrimental influence on the tensile resistance of the material. The variation in strain for the laminated bamboo lumber column sections is linear throughout the loading process, following standard normal section bending theory which is similar as that for the beam.

“…The problem of stability of thin-walled structures under operational static loads was investigated for instance in [6][7][8][9][10][11][12][13][14], where the authors analyse the operation of thin-walled structures with complex open and closed cross sections. They offer a solution to the problem of non-linear stability of the investigated thin-walled structures using experimental and numerical methods [15][16][17][18][19][20].…”

Experimental and Numerical Study of the Buckling of Composite Profiles with Open Cross Section under Axial Compression

et al. 2017

The object of the research are short, thin-walled columns with an open top-hat cross section made of multilayer laminate. The walls of the investigated profiles are made of plate elements. The entire columns are subjected to uniform compression. A detailed analysis allowed us to determine critical forces and post-critical equilibrium paths. It is assumed that the columns are articulately supported on the edges forming their ends. The numerical investigation is performed by the finite element method. The study involves solving the problem of eigenvalue and the non-linear problem of stability of the structure. The numerical analysis is performed by the commercial simulation software ABAQUS®. The numerical results are then validated experimentally. In the discussed cases, it is assumed that the material operates within a linearly-elastic range, and the non-linearity of the FEM model is due to large displacements.

“…Timber-concrete composite T beams and the connection system were produced by steel hooks and by perforated steel plates, both glued with epoxy adhesive (Miotto and Dias 2011). In the past 20 years, the use of fiber-reinforced polymers for reinforcing structural elements has been effective, both economically and for structural performances (Taheri et al 2009;Kureli et al 2013). In recent years, studies related to the reinforcement of wooden construction materials by non-FRP materials such as concrete, glass, steel, and FRP materials that are produced from glass, carbon, boron, and aramid fibres, increased (Motlagh et al 2008;Nowak et al 2013).…”

Determination of the Modulus of Elasticity of Wooden Construction Elements Reinforced with Fiberglass Wire Mesh and Aluminum Wire Mesh

et al. 2017

Laminated composite wooden construction elements were produced with 7 layers of Scots pine (Pinus sylvestris L.). Fiberglass wire mesh and aluminum wire mesh, which were used as reinforcement materials, were pressed with polyvinyl acetate (PVAc) and polyurethane-type adhesives between each Scots pine layer. The highest bonding strength values were obtained from laminated control specimens produced with polyurethane adhesive without using support materials (4.98 N/mm 2 ) and laminated control specimens made with polyurethane adhesive without using support materials (4.39 N/mm 2 ), respectively. The modulus of elasticity in bending perpendicular to the glue line values of all the specimens except the laminated control specimens produced with polyurethane adhesive without using support materials (14800 N/mm 2 ) were lower than solid wood (6720 N/mm 2 ). In contrast, in the experiments for the modulus of elasticity parallel to the glue line, the variables (adhesive, intermediary layer materials) used for all experiments and specimens were effective factors. Although the modulus of elasticity in bending parallel to the glue line values of all samples were higher than solid wood (6720 N/mm 2 ), the maximum value was obtained in the laminated control specimens produced with polyurethane adhesive without using support materials (17800 N/mm 2 ).
