The article includes the analysis of influence of random distribution of assembly clearance of various sizes on deflections and the load capacity of the folding beam based on fixed supports. This analysis includes seven variants of the random occurrence of individual pins in the interconnections between the two-span folded beam components. Measurement results for these variants were compared with the results obtained for the variant with fixed (medium) assembly clearance. Analyses of deflections and load capacity confirmed the correctness of acceptance of the fixed assembly clearance for the calculation of folding bridge. This issue was undertaken for the first time, which is the originality of this study. Keywords: civil engineering, folding bridges, assembly clearance
