EXAMPLE 3. NON-STANDARD STUDY METAL CONSTRUCTION

EXAMPLE 3: 'DESIGN OF A METAL STRUCTURE' 69 - if you select " Coefficient " you must enter a coefficient by the different lengths of the members belonging to this parameter group will be multiplied. If you want the program to take the actual lengths of the members into account when checking the bending bend, select "Coefficient" with a value of 1. If you have some members with different or equal lengths that are laterally secured at the same distances (e.g. at 1/3), then you give the value 0.33 and of course create a separate parameter group to which these members belong. The next parameter is the member's buckling length which depends on the support conditions of the nodes of the member ends always within the buckling plane. OBSERVATION If there has been a Consolidation, then the Bending Length refers to the Consolidated Member. From the " Bend lengths " field you can select the support conditions of the member via the icons. Depending on these, the program calculates a coefficient, e.g. for a double-jointed member = 1.0. Here you select 1,0 in both directions. Then click on the side bend field to have the program perform the corresponding check. Here you need to describe the " Edge Binding " , the " member loading " form by y and z, and the " loading level " . For a detailed explanation of the icons please refer to the corresponding paragraph of the Manual Chapter 9 Sizing. Also, to perform the functionality check and torsional bending, click on the respective fields. The parameters for torsional are the same as those you gave flexural flexure. After you have entered all the parameters, you are returned to the previous window. Here if you select the command " Apply to all members of the layer " then the parameters you set before for member 61 will be applied to all members of the corresponding layer, i.e. the metal beams. You could create layer groups by typing the name DOKOI 2, selecting different parameters and finally clicking on "create new group". This way the members belonging to the "metal beams" layer would have parameters either from the "beams" group or from the "DOKOI 2" group depending on the assignment you would make to each member. Then you select the " Check layer " command and calculation of all the members for the combinations you have already defined starts and at the end a green or
