Sustainable Architecture Creating Arches Using a Bamboo Grid Shell Structure: Numerical Analysis and Design

Abstract

Bamboo is known as a sustainable alternative for green building design, and it has been tied culturally to some regions around the world. However, bamboo’s structural strength for different design scenarios needs more investigation before it is widely adopted. Timber and bamboo have similar mechanical properties, but the latter is a repaid, renewable, sustainable, disaster-resilient system and is versatile, which has more advantages for construction purposes. Natural bamboo and its derivatives have been considered as a high-demand green and environmentally responsible alternative construction material, and this interest is increasing globally. Because of the rapid growth rate and large developing area, it is more useable than the limited timber resource. However, natural bamboo has an anisotropic and nonhomogeneous material property, which varies in multiple directions. There is limited engineering data and investigation of bamboo material and its use in and impact on construction. In this study, three different bamboo models were analyzed by Strand7; each of them had different features in structure and in the major construction material. A new model was proposed by improving the three given structures and was maximized in the mechanical capacity. Some design guidelines were proposed based on the analysis and comparison of different bamboo structures. The model will replace natural bamboo with bamboo scrimber, which is an engineered bamboo derivative that has more uniform material properties.

Hypotrochoidal scaffolds for cartilage regeneration

“…Besides compressive forces, articular cartilage is also subjected to shear forces [ 34 ]. The hypotrochoidal design could prove beneficial as it is known that arches can distribute the shear forces through the entire structure [ 35 ]. Another observation that was made is that the energy lost per cycle in the fatigue test was higher in the r = 0.34 and r = 0.68 hypotrochoidal design compared to the 0–90 woodpile structure, indicating that having less arches in the scaffold resulted in a higher energy loss.…”

Innovative Industrial Use of Bamboo as Key “Green” Material

“…A Europe of high-vignetted Member States today is witnessing several technological advances in some areas of the economy and industry, such as micro-propagation, the selection of superior genotypes using molecular markers, and biomass gasification for energy production and environmental protection. Any bamboo product used on a large scale, and especially on an industrial scale, means that it will be used throughout the economy, especially in the construction [59][60][61], textile, and food industries. Bamboo can be used not only as an advanced sustainable material for engineering purposes, but also as an advanced material in the substitute food industry such as bamboo fibre for better texture performance.…”
