The article presents the results of an on-site test spatial metal farm of an aircraft hangar with a span of 72 m. A comparative analysis of the data obtained by the simulation of the farm from the predicted loads (taking into account the actual geometry) and the on-site tests is performed. During the assessment of the technical condition and testing, significant errors were identified in the design and manufacture of gate frames structures,which could lead to loss of bearing capacity or unsuitability for normal operation. Based on the test results, measures were developed and implemented to strengthen the elements of the farm, repeated full-scale tests were conducted. Based on the foregoing, the span structure is recognized as suitable for safe operation.
