2 Input Data Figure 2.17: Selecting the local member axis systems in the Display navigator of RFEM When buckling is possible about one or even both member axes, you can enter the buckling length coefficients as well as the buckling lengths in the columns C and D or F and G. The same is possible for the table Settings for Member. When you specify the buckling length coefficient β ef , the program determines the effective length l ef by multiplying the member length L by the buckling length coefficient. The input fields are interactive. To define the buckling length, you can use the [...] button appearing at the end of the l ef input fields to determine the distance between two nodes graphically in the RFEM work window. Lateral Buckling Possible Table column H shows you for which members the program performs an analysis of lateraltorsional buckling. The equivalent member length l ef for this type of design can be defined manually or graphically by the spacing of lateral supports. Below the Settings table you find the check box Set Inputs for Members No. If it is ticked, the settings entered afterwards will be applied to the selected or even to All members. Members can be selected by entering the member number or by selecting them graphically with the [Pick] button. This option is useful when you want to assign the same boundary 24 Program RF-TIMBER Pro © 2011 Ing. Software Dlubal
2 Input Data conditions to several members. Please note that settings that have been already defined cannot be changed subsequently with this function. Comment In the final table column, you can enter user-defined specifications for each member to describe for example the selected equivalent member lengths. 2.6 Effective Lengths - Sets of Members Table 1.6 manages the effective lengths of sets of members. It is displayed only when you have selected at least one set of members for the design in table 1.1 General Data. Figure 2.18 Table 1.6 Effective Lengths - Sets of Members The structure of this table is similar to the previous table 1.5. Enter the effective lengths for local as well as for lateral-torsional buckling about the two principal axes of the set of members as described above. They determine the boundary conditions of the set of members that is treated at large as equivalent member. The detail settings also specify the cross-sections that are contained in the set of members. Program RF-TIMBER Pro © 2011 Ing. Software Dlubal 25
