An investigation into the effectiveness of student-led experiential learning for UG architects and the implications of incorporating AR into such pedagogical exercises

This paper focuses on a collaboration between three researchers from two universities in Zhejiang province to explore the pedagogical value of hands-on experiential learning using non-standard materials (in this case, bamboo). The second aim of the project was to explore how Augmented Reality (AR) might be used to improve the efficiency of the learning process for the participants. As a building project, the outcome was largely successful- the undergraduate (UG) student participants were able to construct a 4-metre-tall bamboo structure in the summer of 2020, using active bending, from a 3D computer model, within the timeframe. They were given complete autonomy as part of the project which resulted in problems but also arguably improved the learner autonomy and problem-solving abilities of the respondents over the timeframe. Concerning the use of AR in such projects, this researched identified the value for this purpose but also some very major obstacles, including cost and complexity.

Effects on Morphology and Chemical Properties of Indonesian Bamboos by Carbonization

A simple carbonization technique was applied to utilize Indonesian bamboo resources. Several bamboo species as betung (Dendrocalamus asper), andong (Gigantochloa pseudoarundinacea (Steudel) Widjaja), hitam (G. atroviolacea), tali (G. apus), kuning (Bambusa vulgaris var. striata), and ampel bamboo (B. Vulgaris Scharad) were selected for carbonization. Carbonization was conducted using a laboratory electrical furnace at 200, 400, 600, 800, and 1,000 1,000°C. The morphological and chemical properties of bamboos before and after carbonization were then analyzed. Betung, hitam, tali, kuning, and ampel bamboos had type IVstructure which was the most common bamboo structure, while andong bambo had type III structure. Cracks in the fiber bundle were observed and became more visible with the increase of carbonization temperature.The pH showed a similar trend in all species.As a result of the electric conductivity test, carbonized andong and kuning bamboo showed higher value due to rich inorganic content.Kuning bamboo has a high value of potassium and silica content, which are suitable for use as fertilizer.The chemical structure transition of bamboo during the carbonization process was analyzed by FTIR spectroscopy, and significant changes were observed between 400 and 600°C. These results could be useful fundamental data for promoting high value-added bamboo utilization and improving research in Indonesian bamboo.Keywords: bamboo charcoal, carbonization, Indonesian bamboo, inorganic content, FTIR

Analysis of a self-supporting bamboo structure with flexible joints

Self-supporting bamboo structures are ultralight architectural modules applying bamboo round poles, tensile pantographic grids and textile membranes. The structural system applies articulated flexible joints in polyester ropes and locking bio-composite bandage rings, keeping bamboo bars free of torsion stresses. An experimental 1:3 scale prototype and a full-scale structure were fabricated to make previsions about the physical and mechanical behavior of the structure. The experimental results were verified applying a numerical model for the structure. In turn, the flexible joints were analyzed theoretically. The computer model was analyzed using the finite element SAP2000 program. The numerical results were in close agreement with the experimental results specifically for the structural behavior of the flexible joints.

BAMBOO CANOPY: TOWARDS A LIGHT CONSTRUCTION OF BAMBOO

ABSTRACT Despite the abundance of highly sustainable bamboo, people tend to overlook its structural performance for construction purposes. This paper therefore explores the potential of bamboo architecture to develop light-weight building systems and also to create an effect of lightness. Developed by a team at the School of Architecture of Southeast University, Bamboo Canopy is an outdoor stage canopy in Anji, China, that pushes the boundaries of bamboo as a material for building woven gridshell structure. The work is designed as a long-lifespan bamboo structure, with the design team and locals participating in its construction. Positioned on a public stage, Bamboo Canopy experiments with the combination of sustainable construction and local craftsmanship to produce a highly engaging architectural intervention that activates the existing place. With its wing-like form, it invites visitors to join the performance scene—as they approach the shell, the structure reveals itself—with a 12.4-metre span and 6-metre roof overhang, the canopy covers more than 150 square metres with only 1.2 square metres touching the ground. Through analysing the form, structure and details of this experimental project, this paper clarifies not only the potentiality but also the feasibilities in using bamboo for light construction.
