114 Category 3: Industrial Buildings and Plants 3 T.E. Consulting Engineer Contact Lefteris Tsolakis Address Soudas Av. 23, Crete, Chania 73200 Chania, Greece T.E., Consulting Engineer was founded in 2007 to provide the following civil engineering services: • Technical advice for the development of new buildings. • Technical advice for the restoration/upgrading of existing buildings. • Structural design of new buildings (concrete, steel, composite, timber and masonry structures). • Structural design and assessment of existing buildings. • Supervision of civil engineering works. Due to our experience and our knowledge, we can accomplish even the most exacting projects. T.E., Consulting Engineer has managed over 100 projects in Greece. Owner Christodoulakis S.A. Architect Lykourgos Kalogerakis Engineering Office T.E. Consulting Engineer Construction Period 09/2013 - 12/2013 This project includes an existing single floor industrial plant. The dimensions of the building are about 67.10 m x 45.60 m and the maximum height is about 8.20 m. The structure constitutes ten frames; each of them has five columns. All cross sections were welded and tapered. One part of the buildings constitutes a loft, about 230 m 2 constructed with truss beams and concrete floor. The plant was constructed during 1981. We used SCIA Engineer to create a 3D model of this complex structure. First, we performed the stability analysis to calculate the acr factors. The next step was to perform the linear and non-linear analysis, including global imperfection, using the buckling shapes determined from the stability analysis. The seismic design followed, as well. It was a challenge for us to model precisely the geometry of each member due to the welded and tapered cross-sections. Our aim was to redesign and retrofit the structure according to the Eurocodes.
