Abstract:
Prefabricated modular housing structures have become a promising alternative to site-built structures with equal or higher engineering quality and durability. Major advantages of this technology are fast and cost-efficient construction, reduced labor requirements, and superior quality control due to factory production. The modular design of these prefabricated structures offers the opportunity for research and application of innovative composite materials and structural concepts. Engineered Cementitious Composites (ECC) in combination with light gauge steel joists and steel trusses have been utilized in the development of modular floor panels for prefabrication of housing structures. The need for steel reinforcement in conventional reinforced concrete thin shell construction creates a technological difficulty as the placement of the reinforcing steel is very labor intensive and proper positioning of the reinforcing mats is difficult. The use of fiber reinforced Engineered Cementitious Composites (ECC) helped eliminate these constraints and lead to more efficient prefabricated structural elements.
