Engine -
Rigid analysis method is used for above modules. For footing loosing contact with soil, finite difference method is used, where shear and bending is calculated based on actual out of contact soil block than averaging soil pressures. Different 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. Advanced design options are offered through global settings to control effect of self-weight, top reinforcement design requirements, reinforcement placing direction etc.
Reporting –
STAAD Foundation Advanced reports detailed calculation with all code references and relevant
formulas. With Dynamic sketch feature, to the scale footing drawing is represented in the calculation
sheet along with relevant graphs.
STAAD Foundation Advanced also generated site-ready detail drawings
ADVANCED FOUNDATIONS
STAAD Foundation Advanced offers advanced foundations like mat, vibrating machine foundation, lateral analysis of drilled pier.
Module | Analysis/Modeling Specialties | Design Specialties | Reporting Specialties |
Mat | Auto meshing with quad, triangular or mixed plate shape option; any shape of mat with holes and different thickness; conversion of plate moments to global moments | ACI 318-05, 08, 11 BS 8110, IS 456-2000, AS 3600-2004, CSA A 23.3-04, GB50007-2002, EN 1992-1-1-2004 Pedestal Design Grade Beam Design | Detailed calculation sheet with code references |
Vibrating Machine Foundation | Auto generated solids; auto generated dynamic loads | - (only analysis) | Dynamic graphs per ACI351 |
Lateral Analysis of Drilled Pier | Multiple soil layers, multiple concrete sections; Dual non-linear analysis; p-y curve generation for soil; non-linear concrete section | - (only analysis) | 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 well trusted STAAD FEA engine. For concrete design STAAD Foundation Advanced offers unique approach of converting local plate moments to any specified global direction and perform reinforcement design. 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 option. 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, soil spring generation.
Solids are auto-generated for the given geometry and dynamic analysis is performed by STAAD FEA engine.
Calculation sheet reports all the analysis details 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 state of the art 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.
SPECIALIZED PLANT FOUNDATIONS
STAAD Foundation Advanced offers specialized plant foundations like vertical vessel foundation, heat exchanger foundation, tank annular ringwall foundation.
