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.

Industrialised Building Systems (IBS) involves offsite fabrication in a systematic and controlled environment. The aim of this research is to determine the structural performance of newly enhanced column corbel support for IBS industry application. However, there is no solid data to support the industry in producing safe and reliable IBS structure with newly enhanced prototype. Hence, the objectives of this research paper are to identify failure behaviour, flexural strength, maximum deflection and ductility of the IBS beam to column corbel connection. Scaled 1:5 IBS beams with column supports were prepared according to Buckingham and Similitude Theorem. Result contribution of five specimens were obtained from the flexural strength test. The scaled beam has maximum flexural resistance of 2.2 kNm and deflection of 7 mm. The projected flexural resistance for full scale beam is 1265.6 kNm with ultimate load deflection of 35 mm. Failure behaviours such as shear cracking, flexural cracking and concrete crushing have been identified. The average ductility of the specimen was 3.23 which is higher than 3.0 from PCI design handbook. The newly improved specimen has the load bearing improvement of 32%. Thus, this research has positive outcome that could improve the confident level of the industry user toward this product.

The use of material based on by-products and easily renewable materials in modern building structures is today’s preferred route for long-term sustainable construction and this method of construction also respects the principles of key documents, such as the Kyoto Protocol/ Paris Climate Agreements, Agenda 20-20-20, etc. In the field of light concrete (LC), the long-term effort is to effectively reduce the bulk density to a level where the concrete will still exhibit sufficient mechanical properties, so it would be possible to use it as construction material in building structure and at the same time will exhibit a sufficiently low thermal conductivity for the construction to fulfil strict requirements in the field of thermal protection of building without the need for additional thermal insulation layers. The paper describes the results of the research in the utilization of light-weight aggregate based on foam glass in conjunction with by-product based fibers for the development of light-weight porous concrete with very low density and thermal conductivity.

Since the building made of cement concrete consumes almost half of the total energy generated and accordingly accountable for huge amount of CO2 emission, it is necessary to replace the Portland cement (PC) with sustainable construction material. Similarly, Prosopis Juliflora is a shrub or small tree in the family Fabaceae, a kind of mesquite which is considered to be a potential threat for ground water in South India. Hence, this has to eradicate so as to maintain the groundwater and also to effectively utilize its ash thereby reducing environmental pollution, this can be used as a partial replacement for cement. In this regard, this paper investigates the technical feasibility of using Prosopis Juliflora ash (PJA) as cementitious material by partially (5%, 10% and 15%) replacing cement by Prosopis Juliflora ash. The mixes were evaluated for their fresh, physical and strength properties such as workability, density and compressive strength and the results were compared with the conventional mix. In order to save the environment and to save the resources we have come up with using the Prosopis Juliflora (Semai-Karuvelam in Tamil) ash as the partial replacement of cement. Cement will produce equal amount of greenhouse gas (co2) which increase the global warming. As the amount of cement is reduced greenhouse gases also reduced. Utilization of Juliflora ash as a partial substitution for cement is one of the promising methods to increase the strength and thermal insulation for cement blocks. The strength parameters (compressive strength, split tensile strength and flexural strength) of concrete with blended Prosopis Juliflora cement are evaluated.

Abstract Reinforced Aerated Concrete panel building systems are preferred as wall elements in residences and industrial facilities due to their advantages. The signal issue encountered in industrial facilities is caused by fires that occur. Fire resistance of sustainably reinforced aerated concrete panels was investigated. The wall G3/05 class reinforced panel model to be used for the test was preferred. The panel wall has been subjected to a 120-minute fire resistance test. In this process, 1050 C° temperature was measured on the surface exposed to flames, while the wall temperature was read 50 C° on the other surface, and the heat temperature increased to 70 C° only at the panel joints. The data obtained from showed that the reinforced aerated concrete panels maintain their integrity under fire and resistant to high temperatures. These data that reinforced aerated concrete systems should be preferred, in buildings with human population and high fire risk.

Abstract The meteoric growth in light weight structures have opened on doors to many revolutionary concepts and innovations. Studies have manifested that the lowered weight of the structures somehow help to fight the material cost with a better seismic performance. The hollow core structures aimed reducing the structural weight with an improved structural performance as well. The Concrete filled double steel tubes (CFDST) can be taken as amalgamation of Hollow core columns and CFST i.e. single skinned columns. The co-relation of CFST and Hollow core columns gave birth to Concrete filled double skinned tubular columns (CFDST) which can possess the advantages of both the concepts. A sedulous review of concrete filled double skinned columns is being conveyed through this article. The behavior of confined concrete as well as the confining inner and outer steel in the CFDST model and its overall structural behavior is being succinctly reviewed in this article and a simultaneous comparison of CFDST columns to solid concrete/conventional columns is also being carried out where required.
