2015 CSCE Annual Conference Regina - Building on our Growth Opportunities Conference
Architects and engineers are responsible for designing and building efficient structures with a minimum use of materials and energy. In current paper, the structural design of La Crete Biomass Power plant will be presented. The power plant is located in La Crete, Alberta, Canada. This plant is projected to power over 30,000 Canadian homes. The La Crete Biomass Power Facility will utilize well-established technology to provide communities with an efficient source of energy. The facility is an eight-storey building with a total height of 40 m. One of the structural challenges of this project is a huge 960,000 kg mass (biomass boiler) suspended throughout the entire structure. A system of steel hanger rods is selected to hold and suspend the Eight-storey boiler in its place.
The construction material utilized in this project is steel. Steel structures have been widely used in many applications of civil engineering. The use of steel as a construction material breeds many advantages, such as light structural mass, low maintenance cost, ductility, durability, strength and king fatigue life.
One of the most important design considerations for steel structures supporting heavy mass is the dynamic response especially for post-disaster buildings. Etabs software has been used to evaluate mode frequencies, perform the dynamic analysis of steel structures and optimized the sections of steel members taking into consideration different load cases.
Keywords: steel structures; power plant; earthquake loads; wind loads; mode frequency.
