Concrete Retaining Wall Design
Stability analysis, design and detailing of concrete retaining walls for soil and surcharge loads, and seismic load conditions. The program can consider cantilever, simply supported and propped cantilever walls. The host of input parameters allows you to enter complex wall geometries like sloping walls and toes.
The program allow you to choose between the Rankine and Coulomb theories, and can also incorporate seepage in the analysis. A water table can be specified; it may even be taken above the soil surface to model a liquid retaining wall.
Retaining walls are checked for stability (overturning and sliding at both SLS and ULS) as well as strength (flexure and shear at various positions in the wall and base).
The most common use of the program is to analyse a wall with dimensions as entered. However, functions are available to optimise certain wall dimensions, e.g. the depth of the toe needed to resist sliding.
The program uses the calculated design moments in the wall and base to determine the required reinforcement. This can be taken a step further to generate a bending schedule that you can edit and print with Padds or AutoPadds.
Concrete Base Design
Design of rectangular column bases. The program can design bases with columns, stub columns, or no column. You can enter up to columns (or points of load application), each with multiple load cases. If the base forms part of a larger structure that you have analysed in Frame Analysis, you can link the analysis results with the Concrete Base Design program; this will extract the support reactions and insert them as load load cases.
Design output includes diagrams of the bearing stress distribution, safety factors for slip and overturning (at both SLS and ULS), linear shear and punching shear checks, and required reinforcement for flexure.
