The renovated Jabbeke Town Hall, designed by OYO architects, relies on a load-bearing steel skeleton braced by an eccentric concrete elevator shaft to achieve its light, transparent glass-fa\u00e7ade design. Cobe built a single Diamonds 3D structural analysis model covering both the concrete shaft and the steel skeleton, using it to calculate reinforcement quantities, run strength and stability code checks, and determine the strategic perimeter locations where the steel structure needed extra support because of the shaft’s off-centre position.<\/p>\n\n\n\n
OYO\u2019s architectural design of the renovated Jabbeke Town Hall eyes particularly light and transparent thanks to the large glass fa\u00e7ades and the open office spaces. This light and transparent design is made possible thanks to the load-bearing steel skeleton that is braced by an eccentric concrete elevator shaft. “The Diamonds 3D structural analysis model includes both load-resisting elements,” Bruno De Maegd says. \u201cAnd by the way, I want to stress that Diamonds contains many useful functions to build such a 3D analysis model from scratch. I usually start by defining a series of points in a horizontal reference plane. Thanks to Diamonds\u2019 powerful extrusion and intersection functions, a 3D analysis model can then be built in a very short time.<\/strong><\/p>\n\n\n\n 3D structural analysis using Diamonds lends itself perfectly to designing a sustainable concept for a hybrid structure such as the one of the Jabbeke Town Hall. In the first place, there is the calculation of reinforcement quantities for the concrete elevator shaft. In addition, the steel skeleton can be designed based on the code checks regarding strength (resistance) and stability (buckling \/ lateral torsional buckling), accounting for the position of additional wind bracing elements. Because of the elevator shaft\u2019s eccentric position, it is mandatory to support the steel structure at a number of strategically chosen locations along the perimeter of the building. Diamonds helps to determine those locations in an efficient way. <\/p>\n\n\n\n Partly due to the many adjustments made during the design phase, the Diamonds structural analysis model evolved into a real “all-in model.” This Diamonds model proved to be a vital instrument for an efficient project follow-up, providing us with an up-to-date version of the structural design at all times.\u201d <\/p>\n\n\n\n “This project clearly illustrates how efficiently Diamonds can be used for a wide range of structural analyses<\/strong>,” Koen Van Nevel adds. \u201cJust because Cobe has a particularly varied order portfolio, flexibility is of great importance. Moreover, I continue to be impressed by Diamonds\u2019 capability to develop practical structural analysis models that match best implementation practices.\u201d<\/p>\n\n\n\nDesigning a hybrid steel-and-concrete structure with Diamonds<\/h2>\n\n\n\n
