EXAMPLE 10. OPTIMIZATION OF REINFORCED CONCRETE CONSTRUCTION

EXAMPLE 10: 'OPTIMISATION' 22 Defining the elements of a group can be done either all at once the first time, or by adding elements to an existing group afterwards. You select the existing group from the list and use the "Pick-Select" command to select the elements you want to add. With the option when checked, all the poles of a column row can be automatically selected by graphically selecting any of them. This procedure allows only one element to be selected. For the dimensional domain apply the same as described above for the cross-section dialogue box. For this example it was chosen to lock both dimensions of whole group of 200X30 poles. Finally, the following commands apply to all modules and apply to all sections: • The "Delete All" command: deletes all groups that have already been entered. • The "Delete" command: deletes the specific group you have selected. • The "Initialize" command: restores the limits to their original values as specified in the General Parameters. • Finally, the "Show" command: displays in red the elements of selected group. 2) For the " Beams " section, exactly the same applies as previously mentioned for the poles.
