Efficient Precast/Prestressed Floor System For Building Construction, Eliya E. A. Henin
Efficient Precast/Prestressed Floor System For Building Construction, Eliya E. A. Henin
Department of Construction Engineering and Management: Dissertations, Theses, and Student Research
Precast floor systems provide a rapidly constructed solution to multi-story buildings that is economical, high quality, fire-resistant, and with excellent deflection and vibration characteristics. Conventional precast concrete floor system cannot compete with cast-in-place post tensioning flat slab floor systems when high span-to-depth ratio and flat soffit are required. This is due to the significant depth of standard precast beams, and use of column corbels and beam ledges. This research presents the development of a new precast concrete floor system that eliminates the limitations of conventional precast floor system and provides a competitive precast alternative to cast-in-place flat slab floor systems. …

Super Flex Wall - New Frame System For High Rise Buildings, Purdue Ect Team
ECT Fact Sheets Archive
The "Super Flex Wall" is a structural frame method newly developed by the Takenaka Corporation, used in combination with a core wall (the earthquake-resistant reinforced concrete wall penetrating through the center of the building from the lower part to the top floor) and a structural control method or with a base-isolation method. Part of the structure is cantilevered from the central core along the periphery of the building.
Thermal Testing Of Innovative Building Insulations, Eoghan Frawley
Thermal Testing Of Innovative Building Insulations, Eoghan Frawley
Masters
The main objective of this research was to design and develop a Hot Box to test the thermal properties of Eco-quilt multi-foil insulation. This work began by gaining an understanding into how multi-foil works, how it is installed and examining different variations of this insulation. It was clear at an early stage that there were two conflicting opinions on the thermal performance of multi-foils. One set of tests claimed that the insulation had a thermal resistance of approximately 5 m2oC/W. These tests were carried out in real weather conditions, where temperatures were fluctuating, although one laboratory test achieved similar results. …
