Quick * Easy * Versatile

Serving Since 1994

IBC 2006 & ACI 318-05, & MSJC 2005 support
Unreinforced stem (gravity wall) checked via unreinforced provisions of ACI Ch. 22
Unreinforced heel/toe now checked according to ACI Ch. 22 (e.g. very short heel/toe)
Custom load combination sets can be entered (rather than just a single combination)
Masonry load combinations are now fully exposed & customizable
Stability load combination is now customizable

Full gravity wall support: All components (stem/heel/toe) can be unreinforced
Footing bars auto-extend full width
Two curtains of reinforcement
Shrinkage & temperature reinforcement (for complete detailing, it is not 'checked')
Different f'c values for footing/stem
Different fy values for footing/stem
Different weight values for footing/stem (e.g. can model buoyancy in footing)
Option to "turn off" heel / toe reinforcing (checked as structural plain concrete)

Line/strip surcharge can be applied at a depth below backfill (e.g. for a buried footing)
At-rest earth pressure (frequently used for restrained walls)
Specify backfill depth from footing top or bottom (optional)
Specify the unit weight of the water in the backfill (so it need not be water)

All resultant pressures on the wall are illustrated graphically, along with the underlying equations
All building code equations are displayed, worked out with project-specific values
Pictures of the wall, or of a relevant part of the wall, accompany many calculations
Building code provision (e.g. "ACI 318-05 11.1.1") displayed next to all code equations
Graphics plot of stem moment capacity and applied moment
Graphics plot of stem shear capacity and applied shear
Summary table of all checks including name, required value, provided value, required/provided ratio, and controlling load case

File name printed at the bottom of all report pages
Improved check summary table replaces previous poorly organized check displays
Job number input for display in report header
Detailed report including all design calculations & diagram
Concise summary report
Full-page drawing report with fully detailed drawing of wall cross-section and elevation
File name printed at the bottom of all report pages
Report headers display basic company information, plus project title, notes and job number
Company logo displayed in header (optional)
DXF file export

Code provision reference printed with each group of equations
Explicit calculation & display of lateral pressures on the stem only
Table listing forces used in bearing force calculation
Clearer than old equations
Stem shear is graphed (illustrates shear @ section junctions)
Check summary side pane shows unity (required/provided) ratio
Check summary view has more information (e.g. controlling load combination)
Lateral support reaction prominently displayed right on-screen in force calculations
Checking of multiple load combinations now much more exposed
Bearing eccentricity check now calculates & displays actual e, allowable, & ratio
Development & lap lengths calculations are clearer and organized onto a dedicated tab

Option to indicate sliding restrained by external entity (e.g. slab)
Option to include or neglect the bearing pressure beneath the heel for strength checks
Option to ignore stabilizing contribution from passive pressure @ toe
Options to include the vertical component of the backfill pressure for overturning, sliding, and bearing pressure checks (individual option for each)
Option to include surcharge forces in the sliding and overturning checks
Option to use surcharge forces for bearing pressure calculation
Option to neglect the weight of the soil over the toe
Option to factor earth weight as either dead load or earth load
User-specified coefficient of friction between footing & subgrade
User-specified wall friction angle (used if backfill pressure is calculate via Coulomb theory)
Automated Design Commands (Optional)
Automatically choose footing reinforcement
Automatically choose stem reinforcement
Automatically sets required bar embedment lengths and lap splice lengths
Automatically positions key to embed stem bars, also such that reinforces key
Automatically designs shear key to resist sliding
Specify preferences used in all design functions: which bars are available, which spacing to use, which length increments to consider, etc.

Multiple projects in a file, organized in a tree on a "home" page
Menu to quickly create walls of a particular type (cantilever, restrained, gravity)
Have a 'Notes' page where you can enter project-specific comments (printed in report)

Segmental / MSE walls
Multi-level basement walls (multiple lateral supports)
Soldier pile walls
Shrinkage/Temperature reinforcing may be entered, but it is just for detailing, it is not "checked"
Rock anchors
Walls without footings
Walls on pile foundations
Counterfort walls
Strength design of masonry walls (currently only ASD)
Sheet pile walls
Multiple soil layers (other than a saturated layer beneath the water table)
