Kayalar Chemistry Management Building, Research and Development Center

Results of National Steel Structure Design Awards 2014

Structure consists of three sections; Office, R&D Center and Canteen. Structure was formed in accordance with its location in premises and facility boundaries where R&D Center and Canteen building are located close to the facility with administrative building façade facing the road in front of the facilities. Steel supporting structure is used to pass large spans in order not to prevent open office use in interior space matching oval and outward façade of the building.
Foundation system of the structure is raft foundation with bored piles having 65 cm of diameter and reaching solid ground. A reinforced concrete basement is constructed under the whole building and soil pressure is countered with reinforced concrete shear walls. No expansion joint exists in the basement and the floor is solved as a whole. Offices, Research & Development Center and canteen areas are separated with expansion joints in other floors of the building.
Office section consists of one basement, three normal (steel) and one terrace roof (steel) floors. Columns are used only in the façade of the space used as office building and 12-meter span is passed without any columns on the interior, allowing the use of open offices.
Office building supporting structure is designed as steel frame with normal ductility. Steel supporting structure is a frame system transferring moment in both directions. All slabs (except the roof) are designed as composite slabs with a thickness of 12 cm whereas the roof consists of steel roof beams and purlins. Terrace area finish consists of protective concrete on heat and water insulation over composite slab.
Research & Development Center section consists of a basement and three normal (steel) floors. Steel supporting structure of this section is also designed as steel frame system with normal ductility. Steel supporting structure is a frame system transferring moment in both directions. All slabs are designed as composite slabs with a thickness of 12 cm whereas the roof is designed as terrace roof. Terrace area finish consists of protective concrete on heat and water insulation over composite slab. Fresh air units are located on the terrace roof.
Structural system of the building was solved with 3D modelling with SAP2000 software. St-44 grade IPE, HEA and HEB series cross-sections were used for supporting structure system. 10.9 grade bolts were used in moment-transferring connections whereas 8.8 and 5.6 grade bolts were used in other connections.
