Precast joist floor slabs

The "Precast joist floor slabs" module is used to analyse and design the following types of floor slabs:

• Precast reinforced joist floor slabs
• Precast prestressed joist floor slabs

The data sheets or approvals for these slabs have been provided by various manufacturers and are included in the program.

Library of precast joist floor slabs

The generated precast joist floor slab sheets can be saved together with the manufacturer's floor slab sheets included in the program.

Design options

The program has several design options with suitable default values that can be configured (minimum lengths of top reinforcement, minimum moments to cover with slab reinforcement, deflection limits, covers, rounding of bar lengths, etc.).

Results output

For precast joist floor slabs, the program displays the following results on the drawings and on the screen:

• bending moments increased per metre of width;
• shear force per metre of width at the supporting edge;
• type of reinforced or prestressed joist;
• type of lattice in precast reinforced joists;
• top reinforcement.

The program has tools for matching the design results so that uniform results are obtained to make it easier to interpret the drawings.

User license

For CYPECAD to be able to analyse and design in situ joist floor slabs, the user license must include the "Precast joist floor slabs" module in addition to CYPECAD.

Other features

To access other features offered by the program, there are several modules which can be found on the "CYPECAD modules" page.
