Calculation of load capacity of closed steel supports for galleries made from steel profiles (VÚOUV)

Popis výsledku v původním jazyce

The software calculates the load capacity of the yielding and non-yielding closed steel supports made from TH29 and TH34 (steel 31Mn4 and 31Mn4+QT) and K24 (steel H60U). In addition, K24 might corrode and the cross-section might reduce evenly by 10%, 20% or 30%. The calculated uses the 1st order theory. It is based on assumption that the support is loaded with an active continuous load applied from top and sides on the mining or underground work and with an axial force applied in the specified point. It is possible to change the side/vertical loads. The support is also subject to passive forces induced mainly in base surface (and in other points along the perimeter) where the reason for such forces is interaction between the support and the neighbouring rock environment or fill rock. The Winkler's model was used to solve the interaction. The load capacity is designed pursuant to ČSN EN 1993-1-1 (Eurocode 3: Design of steel structures). An alternative design uses rather high ultimate moments corresponding to the specified steel section and steel grade. The support may consist of 3 up to 15 circular segments. Each segment is defined by its length and radius of curvature. For each segment, it is possible to define the coefficient of yield of the solid rock or fill rock. The load capacity of the yielding closed steel support is limited by the slippage resistance that ranges between 100 kN and 350 kN with the 50 kN step. Using the software, it is possible to calculate flexibly the load capacity of the closed steel support with the side/vertical load ratio ranging from 0 to 2 and the step between 0.1 and 1.
