EXAMPLE 2. FORMAL STUDY METAL CONSTRUCTION

EXAMPLE 2: 'DESIGN OF A METAL STRUCTURE' 46 To automatically generate the program and the combinations for the additional loads (snow, wind x, wind z) you have to select from the 3 failure equations and the 3 functionality equations located in the top right part of the window. Select all equations, so that the combinations generated will be based on Eurocode 1. (If respectively only the 1 h and 3 h failure equation and the 1 h functionality equation are selected, then the generated combinations will be based on the EAC). In addition to the "Default Combinations" you can add others with loadings from other analysis scenarios. EXAMPLE For this example you will select all 3(failure)+ 3(functionality) equations and click "Calculate". However, in order to take the additional loadings into account you will need to enter the following in columns LC8, LC9 and LC10: In column LC8 you put: - in place of the Static Snow Typical script - in place of the charge 1 (the first charge of this scenario) - in the type position NULL (since snow is not a permanent, mobile or seismic load) - at the position of snow actions<1000m - in the description field the word CHONI (optional, you can give any name you want) Similarly for other 2 loadings of this scenario and for the loadings of the 2 wind scenarios , the values shown below:
