Light-weight steel buildings caused the construction industry attention is due to low material costs and rapid construction. After typhoon Morakot, 2009, the first extensive use light-weight steel construction for residential projects in Taiwan. Because of the advantages of light-weight steel construction have been used in reconstruction works, can face difficult conditions such as limited budget, duration of compression and a large number of construction.
Since 1999, Taiwanese architect, Hsieh Ying-Chun and his team have designed light-weight steel buildings in Cooperative Self-build Construction concept, used in 921 earthquake, Wenchuan earthquake and Typhoon Morakot post-disaster reconstruction projects, the purpose is to help victims to participate in the reconstruction work. Therefore, construction process must develop the corresponding method of operation from planning and design to construction. The purpose of this study is to investigate the impact of this concept that “Cooperative Self-build Construction” for light-weight steel buildings design and the combination types between structure and envelope.
The conclusions of this study as follow: 1) The impact of this concept that “Cooperative Self-build Construction” for light-weight steel buildings design. 1. For structure design: ▪ Openness the structure design: The structure design can accommodate the use of different materials. ▪ Simplify the production: Rapid production of the material in the factory. ▪ Simplify construction: That material can be quickly assembled on site. 2. For building envelope design: ▪ Local materials as a priority. ▪ Construction method has the advantages of regional. ▪ Bonding the structure and the shell easy to modify. ▪ Reduce on-site processing and material consumption. ▪ Component prefabrication can improve quality and efficiency. 2) The combination types between structure and envelope 1. The building envelope combination of procedures: linear component → combined into a planar → grouped into blocks. 2. The building envelope combination of the pattern: single side stackable shape, both sides of the planar stacking, watering body shape consolidation, massive stack. 3. The bonding forms of structure and envelope: roller joint, hinge joint, fixed joint. 3) How to assessment the materials of the building envelope and the method of fabric. The conclusions of this study in cooperative Self-build Construction provide the bill of materials, material selection principles, the combination types between structure and envelope and structure performance assessment methods.
