83 Category 3: Industrial Buildings and Plants 3 Owner Saudi Electricity Company Architect CMI Energy General Contractor Daelim Industrial Co. Engineering Office I.d.d. Engineering Construction Period 11/2011 - 01/2014 The power plant is a raw-oil plant. The electricity is made by burning raw oil. The cylinder is 60 m high and its diameter is 4.6 m. The ground surface at the bottom of the transition piece is 26 x 13 m². In total, the analysed structure is constructed 10 times on site. The building contains heavy equipment such as boilers and a lot of piping. The internal furnace structure is modelled in a separate SCIA Engineer project. The building meets seismic requirements (0.30 g) and the eigenfrequency of the main structure is designed to comply with the wind vibration mode of the American standards. SCIA Engineer is used with steel check according to the American standards. Seismic analysis, general vibration for wind vortex, plate elements and stability check are used to verify that the model meets all the above given criteria. The structure of the cylinder and its transition piece is modelled with 2D-plates and stiffening beams. The general stability check is also used for some parts. The difficulty is the buckling effect of the plated transition piece which is self-supporting and takes the weight of the cylinder on top of it. Another challenge is to have all the connection details matching together. The client reached a 30% reduction in the weight of steel thanks to a good optimization of the upper shell plate thickness.
