Recently, we achieved a significant breakthrough in our steel structure hangar project in Kazakhstan. The hangar features a dual adjacent grounded curved arch system to create a spacious interior with excellent structural integrity. Two structural alternatives, including curved trusses and curved welded H-beams, were adopted for finite element calculation and comparative analysis. Standard computational reports were compiled thoroughly for technical validation and submitted to the client’s engineering team for official review.
Snow load resistance constitutes the primary technical difficulty of this design. The project is specified with a basic uniform snow load of 200kg/m² per local code. Considering the non-uniform snow accumulation effect on curved arch roofing, three critical uneven snow load cases were simulated and analyzed. Local snow load concentration under extreme accumulation conditions yields a peak load up to 400kg/m², bringing stringent challenges to the structural bearing capacity, rigidity and overall stability of the long-span arch system.
Through refined structural optimization and precise load calibration, the design effectively resists extreme and asymmetric snow loads and fully meets building code requirements. The standardized computational analysis and complete documentation significantly facilitate technical auditing by local structural engineers and streamline governmental approval procedures, providing a reliable technical guarantee for the project’s construction and long-term safe operation.
