Once the Calculation Options dialog box is opened for deep-beams and the General tab is selected, the dialog box shown below will appear on the screen.
In the top part of the dialog box the calculation method for deep-beams may be selected:
- according to the French BAEL code - static calculations are performed according to the simplified method described in BAEL 91 code (annex E1); reinforcement calculations are carried out according to the method described in BAEL 91 code (annex E5).
Limitations of the method:
The maximum difference in height between the neighboring spans equals 1 m.
The distance between an opening and the deep-beam edge cannot be less than the opening width.
A detailed description of principles of the deep-beam modeling by means of the BAEL simplified method is given in the topic Calculation of deep beam reinforcement - principles.
- applying the Finite Element Method - based on the deep-beam geometry defined by the user the program generates automatically a model for the finite element method; if this option is selected, the user should determine a preferred size of the finite element.
