Longitudinal slab reinforcement
The basic premise is to provide a consistent background of basic reinforcement throughout and then add additional reinforcement if required. The graphical unity ratios below clearly show the failing zones of the slab, where additional reinforcement need to be placed.
MasterKey: Concrete Slab Design offers two types of additional reinforcements:
- Peak reinforcement: can be placed over a point (for example column head, wall end or point load). Peak reinforcement zone contains two sets of orthogonal bars (shown below)
- Strip reinforcement: similar to the Peak reinforcement, but only has reinforcement in one direction (parallel or perpendicular to the centerline of the reinforcement zone). Can be placed with drawing the centerline of the strip
Concrete Slab Design Software. RetainWall is a software mainly developed for the purpose of designing a concrete or masonry retaining wall. The wall may retain soil or other granular material. It analyses the stability of the wall based on the loads and resistances, and results in.
The Auto Design function can find, not just the most economical reinforcement solution (bar sizes and spacing) but is also able to optimise the size of the additional reinforcement zones. The below design is using inner & outer peak strips to reduce the rebar used.
Punching shear design
Punching shear design check can be placed on column heads, wall ends and corners.
The design check automatically identifies the position (internal or external), the column/wall shape etc. and determines the punching shear parameters.
Slab Design
If punching shear reinforcement is required, the design automatically creates the reinforcement arrangement based on the selected rebar layout.
MasterKey: Concrete Slab Design offers four types of rebar layout:

- Equally spaced on perimeter
- Radial layout
- Even grid
- Cruciform for support face
