A steel–bamboo SI (skeleton–infill) system with steel frame as the skeleton and bamboo box as the filler is proposed, which realizes the requirements of building assembly and sustainable development. As a first step in studying the seismic behavior of the steel–bamboo SI (skeleton–infill) system, a simplified plane steel frame–bamboo infilled wall ...

Novel bamboo I-beams fabricated from bamboo oriented strand boards as structural members were investigated. Bending tests were performed to determine the stiffness and strength properties of bamboo I-beams. The results showed that the stiffness and strength properties exceeded the requirements of APA EWS Performance-Rated I-joist in PRI-400-2012. I...

This study investigated the use of glycerol–fatty acid sodium soap mixtures to delignify woody biomass as a model for utilization of crude glycerol by-product from biodiesel manufacture. Lignin-bearing glycerol was also produced. Delignification was carried out using glycerol mixed with sodium salts of laurate, stearate, oleate, or linoleate at 100...

Wood is used as an interior material in Japan, and it is empirically known that contact with wood induces relaxation in humans. However, evidential data regarding these physiological effects are lacking. In this study, we examined the physiological effects of tactile stimulation based on measurements of brain and autonomic nervous activities by usi...

In this study, dynamic changes in structural polysaccharide deposition on the plasma membrane and cortical microtubules (CMTs) behavior were monitored in protoplasts isolated from white birch callus using confocal laser scanning microscopy and atomic force microscopy. We focused on the influence of an environmental stimulus on cell wall regeneratio...

The aim of the study was to develop three-layer medium-density fibreboard (MDF) manufacture by adding the coarse fibres in the middle layer, like three-layer particleboard. The liquid urea–formaldehyde (UF) resin was reduced from 10.5 to 6.5 wt% in the middle layer of the MDFs. The UF resin content was kept constant at 10 wt% in the surface layers ...

The moisture sorption behaviour of wood strongly influences the durability of exterior-coated wood. Wood characteristics are known to influence the water sorption of uncoated wood. Despite this, the majority of the research on coated wood has been focused on the coating properties. This study aims to investigate the impact of heartwood, sapwood and...

The strain associated with orthogonal cutting with and against the grain of hinoki (Chamaecyparis obtusa) was measured. Digital image correlation method was used to measure strain distributed in the area within 0.5 mm of the cutting edge. The relationship between strain and the use of different grain angles (− 15° ≤ φ\documentclass[12pt]{minimal} \...

Annual ring width, warp, dynamic Young’s modulus, and static bending properties were evaluated for 2 × 4 lumber produced from Larix sibirica trees naturally grown in five different provenances of Mongolia. The lumber was also visually graded according to Japanese Agriculture Standard for structural lumber for wood frame construction. Mean values of...

The incorporation of recycled papers, paperboards and Tetra Pak as filling materials in brittle matrices presents an interesting approach in the utilization of waste materials for building construction. This paper examines the compressive strength and microstructure of gypsum-bonded wastepaper-based composites. Recycled wastepaper of various types ...
