Sažetak
The load bearing mechanism of trapezoidal profiled thin sheets subjected to transverse load is manifested through the occurrence of local buckling in the flat unstiffened part of cross section subject to compression, once a certain intensity of pressure is reached.The testing was performed for the negative position of sheet and for the positive sheet position. The stresses are reduced at the point of local cross-section buckling, while stress concentration occurs at the portion of cross section next to the edge bracing. Differences obtained in the trapezoidal sheet limit load and deflection values may be explained by the fact that in case of negative trapezoidal sheet position a wider zone is in compression in the area of maximum bending moment on the span. In case of positive trapezoidal sheet position, the wider zone is in compression above the bearing which would otherwise make it more stable. This analysis shows that the stability of the zone in compression plays a principal role in the bearing capacity of trapezoidal sheets.
