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.
