Define:
- Define > Material,
- Concrete, modify.
- Fy = fys = 60ksi,
- f’c = 4ksi
- Define > frame section.
- Add rectangular, name B15 * 12. Reinforcement,
- Beam clear cover top = bottom = 2.5”
- Name = slab
- Define > Area sections,
- Asec 1 modify,
- thickness bending = membrane = 6”.
- Define > load cases, add live load.
- Define > add default combo check concrete,
- Convert to user check boxes.
- Draw > quick draw area, draw the area.
- Draw > quick draw frame draw beam, B15 x 12
- Select edge paints at both ends

Design:
- Design > concrete frame design
- Design > Concrete frame design
- Verify all members passed
- All members should pass otherwise increase beam size to pass
- Design > concrete frame design > display design/np Select longitudinal reinforcement
- For beam, for both upper and lower face, select max value & for column select max value and calculate No. of bars
