CRANEWAY | Results

All results are arranged in result windows sorted by different topics. The design values are illustrated in the corresponding cross-section graphic. The design details cover all intermediate values.

General Stress Analysis

CRANEWAY performs the general stress analysis of a craneway girder by calculating the existing stresses and comparing them with the limit normal, limit shear, and limit equivalent stresses. Welds are also subjected to the general stress analysis with regard to parallel and vertical shear stresses and their superposition.

Fatigue Design

Fatigue design is performed for up to three cranes operating at the same time, based on the nominal stress concept according to EN 1993-1-9. In the case of fatigue design according to DIN 4132, a stress curve of crane passages is recorded for each stress point and evaluated according to the Rainflow method.

Buckling Analysis

Buckling analysis considers the local introduction of wheel loads according to the EN 1993-6 or DIN 18800-3 standards.

Deformation,

Deformation analysis is performed separately for the vertical and horizontal directions. The available related displacements are compared to the allowable values. You can specify the allowable deformation ratios individually in the calculation parameters.

Lateral-torsional buckling analysis

The lateral-torsional buckling analysis is performed in accordance with the second-order analysis for torsional buckling considering imperfections. The general stress analysis has to be fulfilled with the critical load factor greater than 1.00. As a result, CRANEWAY displays the corresponding critical load factor for all load combinations of the stress analysis.

Support forces

The program determines all support forces on the basis of the characteristic loads, including dynamic factors.
