166 3 Category 3: Design of Industrial Buildings and Plants Software: Scia Engineer Fire Protection Ceiling for Storage Hall - Hamburg, Germany Customer HHLA - Hamburger Hafen und Logistik AG has decisively shaped Hamburg’s rise to become one of the world economy’s most important hubs. With innovative terminals, an ecologically exemplary transport network and comprehensive logistic services, today it stands for the intermeshing of global goods streams between Europe and overseas. HHLA was founded as HFLG in 1885 to develop and run Speicherstadt (Warehouse District) of Hamburg. This was designed as the largest, most modern logistic centre in the world, and even at that time it was optimally intermeshed with networks of different carriers (sea, rail, and road). HHLA offers its clients an immense range of services along the entire logistics chain, from the quay wall in the overseas port to its customers in the hinterland. The order A big existing storage hall from the middle 80’s was indicated as a temporary storage place for the oncoming parts for the production of the Airbus. Due to the modern rules for fire protection the inner space of the hall has to be reduced to ensure the functionality of the sprinklers. Because the statics of the hall did not consider the possibility of the additional load (about 30 kg/m2 required for the conventional solution with fire resistant plates), the client was looking for alternatives. A membrane ceiling with a fire resistance glass fabric spanned over the prestressed cable network was suggested. The additional load was assumed to be 1.0 kg/m2. Technical data The existing hall consists of a filigree crossed steel framework beam roof with paired girder elements. The roof bases on the inner and outer facade steel columns net. The roof and side wall bracing stabilized the structure. The existing dimensions of the inner storage space were about 90.0 x 117.0 x 18.0 m. Due to the fire resistance rules, the required height of the storage hall has to be lower than 15.0 m. About 12.000 m2 fabric material and 6.000 m cables were needed. The biggest challenge was to consider the existing roof geometry with all structural and additional elements such as 5 bands of light across the whole roof, existing old sprinklers and ventilation tubes, differently placed bracing, stability cables and truss elements. The new ceiling was not allowed to have more than 3% openings! Software and model Scia Engineer was used for the processing of the whole project. The original execution plans were not found, but after very detailed surveying of all main parts of the structure the hall was completely build up as a 3D Model and the required geometry of the ceiling was settled. To optimize the fabrication and montage the ceiling was divided on the strips with two different widths due to the fabric production geometry. According to the settled strips the cable net with required additional facade beams, anchors and intermediate connections were planned. Calculation and production The calculation, design and optimisation of the cable structure with the required additional facade beams was made according to the IIIrd order theory. The deflection of the ceiling has to be limited to 20 cm. Verification of the existing facade columns with additional load from the ceiling was done too. The next steps were the design of the connections for the new structure. At least design and confectioning of the fabric strips with connections to the cable net and to the existing structure was processed. Execution The structure was completely planned und produced in 3 months. The General Constructor was Planex Technik in Textil GmbH. Nevertheless the optimisation, about 280 different types of fabric stripes were derived from the 3D model due to geometrical demands. The total project cost amounted to approximately 370.000 Euros.
