Real Slabs


 

 

The concrete beam program can be made to design the beams using the slab rules by selecting As a Slab (no links) in the Beam & Column Links Options above.  This will then apply the slab rules to the beam cross-section.

As a more practical alternative select the “Design as a Slab for 1000mm …” option.

 

This will use a slab section of 1000 mm wide. 

All moments and shears will be proportioned to the values for section analysis width.

Main bars are input and stored as a pitch. Eg T12 @ 225 and not as an approximate pitch 6-T12 @ 166

Bar pitch changed by using the mouse on the pitch value.

 

Above: set to “As Slab (no links set)”.

Note the odd spacing. Still dealing with a physical number of bars in a beam width set in analysis.

 

Above: set to “Design as a Slab for 1000mm..

Note: the exact spacing and design will be for 1000 mm wide section..
