STRENGTH CALCULATION OF AN INDUSTRIAL HALL WITH A GANTRY CRANE

Abstract

The analysis shows that the profiles play an important role in the displacement values due to static stresses. The results obtained in the industrial parter floor show the structure's ability to withstand standard wind and snow loads, but also after a possible earthquake. After the static analysis, values close to the norm-accepted limit were recorded. The advantage of metallic constructions in the field of industrial halls is obvious: weight reduction compared to reinforced concrete constructions; increased safety due to the homogeneity of steels; reduced execution time, etc. In combined cases for determining the ultimate fundamental load the maximum combined bending stresses and axial stresses do not exceed the 150 MPa admissible stress; the largest combined stresses are recorded in the bundles and not the length of the bars, with regard to the welding connection of the bar elements (roof and upper longitudinal bracings). The maximum total displacements of the rolling bridge are in accordance with the applicable regulations (arrow / bar length <1/600). Relative displacements greater than 1/600 are recorded in bars without technological importance. The track of the bridge is relatively less influenced by the action of the external loads of the hall, it is supported by its own pillars. It is absolutely
