Karel Albrecht General Contractor City Kladno Engineering Office P-H-A Atelier Construction Period 09/2015 - 04/2016 Building geometry and structural system: The new roof covers the existing stage built in last century for Sokol movement athletic stadium. The new steel columns were founded on piles drilled into existing limestone gravity wall of grandstand. The new roof is made of steel spatial trusses with the span 4 x 13.5 / 4.1 m. The roof was cantilevered on both sides. The length of the cantilevers is 2 x 7.0 m. The roof was calculated in SCIA Engineer and exported to Tekla using the SCIA 2 Tekla module. The designer used the perfect combination of design and fabrication of steel constructions. For a fast feedback, the designer used 3D export from Tekla to a browser. The whole structure was calculated in a complete 3D-model. In this way, the total influence of all external loads can be considered and the global stability can be calculated, with the accompanying deformations, and details of connections. The total weight of the structure is 56.0 t. The bill of material calculated by SCIA Engineer was the first input for the preliminary offer to the contractor. The total price of the structure given by the developer was limited. SCIA Engineer and Tekla software helped to find the optimal structure.
