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

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.

Plant foundation modules uses rigid analysis method. Plant foundation modules takes special
recommendations made by PIP, API into consideration where applicable. STAAD Foundation
Advanced generates Seismic and Wind forces on vessel per ASCE7-05 / IS 875, / IS1893 / API 650. It
also auto generates load combination based on ASCE 7 or PIP guidelines.
