Rigid analysis method is used for above modules. For footing losing contact with soil, an iterative method is used to find the region in contact. Shear and bending are calculated based on actual region-in-contact and not based on averaging soil pressures. Critical load cases are detected for each check (e.g. soil bearing check for each corner, sliding and overturning, shear and bending check in each direction)
If footing is resized at any step, design engine starts back from soil bearing check to ensure updated self-weight is considered in the calculation. Options are offered through global settings to control effect of self-weight, top reinforcement design requirements, reinforcement placing direction etc.
STAAD Foundation Advanced reports detailed calculation with all code references and relevantformulas. With Dynamic sketch feature, to the scale footing drawing is represented in the calculationsheet along with relevant graphs.
STAAD Foundation Advanced also generated site-ready detail drawings

Detailed calculation sheet; P-Y, deflection, moment-curvature graphs
Mat foundation module offers any shape of mat supported on soil or on piles with various forms of loading like line load, rectangular, circular & irregular pressure load, point load, reaction load etc. Analysis is performed by the STAAD FEA engine. Stability of the mat against sliding and overturning is reported for each service load case. For concrete design local plate moments are converted to any desired global direction for performing reinforcement calculations. Moment below columns are neglected for reinforcing design. Multiple mat thickness can be assigned though control regions and control regions can be neglected from concrete design if needed.
Vibrating machine foundation offers single, combined & combined with gear box options. It offers rotating and reciprocating equipment as load generators. For dynamic load calculations and soil spring calculations it follows ACI351.3R-04 for dynamic load generation and soil spring generation.Solids are auto-generated for the given geometry and dynamic analysis is performed by the STAAD FEA engine.Calculation sheet reports the analysis results along with code references used for dynamic load and soil spring generation. It also produces dynamic graphs per ACI351.3R-04 for various severity and permissible displacement checks.
Lateral analysis of drilled pier offers dual non-linear analysis (where pile concrete section behaves non-linear and supporting soil reactions are also non-linear). It offers multiple section choice as circular or rectangular section with or without casing. For various soil layers, p-y curve generation method can be specified. User can specify batter angle, ground slope, factor of safety for skin friction & tip resistance.
