Abstract

This study investigates the impact of foundation connection uncertainties on the structural reliability of single-span greenhouses by means of a Monte Carlo simulation. Comparative analyses between fixed-support conditions and those allowing displacement and rotation revealed significant differences in the structural behavior. Under fixed conditions, the maximum von Mises stress remained within the allowable limits (182.6 MPa), with a failure probability of 27.0%. However, with displacement and rotation, the stress exceeded the allowable limits by 50.8% (445.4 MPa), with the failure probability increasing to 50.7%. The results here indicate that the snow unit weight significantly influences structural safety and that the ground-structure interaction is a decisive factor with regard to the structural behavior. Current design standards may be inadequate, particularly given the increasingly extreme environmental conditions caused by climate change. This study suggests incorporating snow unit weight criteria and ground-structure interaction guidelines into greenhouse design standards.
