1. General Information
1.1 Overview
AFES is a comprehensive one-stop solution for all your foundation engineering and design needs. Due to AFES’s
capability to make reports, construction drawing including bar schedule, BOM and generation of 3D
CAD(PDS/PDMS) foundation modeling data, it is very powerful solutions for the analysis and design of all kinds
of foundation.
1.2 Background
Foundation design is usually done manually thus entailing large storage manpower needs, which is
uneconomical and in turn leads to difficulties in meeting quality requirements and deadlines.
The shortness of work period for project, frequent design changes of upstream parts, difficulties in assuming
the size of foundations for site and the need to check interference between foundation, underground piping,
and electrical cable trench, and coordination with other teams are some of the difficulties encountered during
the design stage of a project.
With the absence of a one-stop commercial solution that can solve the above mentioned problems, AFES is the
system that can produce all type of foundation analysis and design needed for the construction of foundations,
quickly and economically.
1.3 Application Area
Energy, Petrochemical, Refinery, Gas, Water Supply, Treatment and Recycling Plants

1.7 Basis of Foundation Design
The following assumptions from the basis of foundation design procedures used by AFES.
- The program designs a spread and pile supported foundation.
- All piers and footings are assumed to be rigid with respect to load, soil bearing and pile load
distribution purposes.
- All loads at the top of pier are assumed to act the center of the pier.
- Factored soil bearing pressure required for obtaining bending moment in the foundation is determined based
on uni-axial in each strip separately.
- To determine the shears and bending moments in the foundation, the foundation is divided into many strips
and the values are calculated at critical and maximum conditions.

1.9 AFES Program Theory
AFES program has the facility to obtain results of the Conventional and Finite Element Method(=FEM) for
foundation analysis and design. The user may use one of the two design methods stated above.
1) Conventional Rigid Method
The purpose of a footing is to transfer safely to the ground the dead load of the superstructure
(=weight), and all other external forces acting upon it. The type of foundation is also influenced,
though to a lesser degree, by the geographical location and climatic of the site, frozen depth, etc.
AFES performs a complete structural analysis and design of foundations as following below. The
program uses the following criteria.
AFES use two types of load combinations ; Service(=Unfactored Load) and Design(=Factored Load).
Service load combinations are used to calculate the soil and pile capacity, overturning moment, and
sliding forces for comparison with allowable soil and pile capacity defined in the Setting of Constant
window. Design load combinations are used to design the footing and pedestal for flexural and shear
as per chosen building code.
1) Conventional Rigid Method
a) Soil Bearing Pressure (Shallow Foundation)
b) Pile Capacity (Deep Foundation)
c) Overturning Moment (Shallow Foundation)
d) Sliding Force (Shallow Foundation)
e) Shear and Flexural Design (no shear reinforcing assumed)
f) Two way Shear Design
g) Design of Piers
a) Soil Bearing Pressure (Shallow Foundation)
AFES calculates the soil bearing pressure for all service load (=unfactored load) combinations
from the allowable soil pressure evaluated by principles of soil mechanics. Any eccentricities,
additional bending moments and/or horizontal shears shall be considered in the evaluation of
the maximum edge pressures.
Soil pressure under the footing is assumed to be linear. For eccentrically loaded footings, the
soil pressure may become tension under the part of the footing. In such cases the program
set pressure values in uplift zones to zero and calculates new values for the revised

equilibrium condition due to “Hand Book of Concrete Engineering” edited by Mark Fintel.
The maximum soil pressure should not exceed the allowable bearing defined in the Setting of
Constant criteria window. AFES supports biaxial and uniaxial soil bearing pressure analysis.
Qa >= ΣV_appl / Af ± ΣMx / Zx for Uniaxial
Qa >= ΣV_appl / Af ± ΣMy / Zy for Uniaxial
Qa >= ΣV_appl / Af ± ΣMx / Zx ± ΣMy / Zy for Biaxial
Where,
Zx = 1/6 x Lx x Ly2
, Zy = 1/6 x Ly x Lx2
: Section Modulus, Af : Footing Area
b) Pile Capacity (Deep Foundation)
The user provides the following pile parameters such as representative pile name, type of pile,
diameter, length, thickness, elastic modulus, area, allowable Vertical/Lateral/ Uplift pile
capacity. Based on these parameters, program calculates the maximum pile capacity. The
maximum pile capacity should not exceed the allowable pile capacity. AFES supports biaxial
and uniaxial pile bearing capacity analysis.
Ha_pile > = ΣH(i)x_appl / N_pile for Uniaxial
Ha_pile > = ΣH(i)y_appl / N_pile for Uniaxial
Ha_pile > = √(ΣH(i)x_appl2
+ ΣH(i)y_appl2
) / N_pile for Biaxial
Va_pile > = ΣV_appl / N_pile + ΣMx_appl x Y(i)/ ∑Xi2
for Uniaxial
Va_pile > = ΣV_appl / N_pile + ΣMy_appl x X(i)_x / ∑Yi2
for Uniaxial
Va_pile > = ΣV_appl / N_pile + ΣMx_appl x Y(i) / ∑Xi2
+ ΣMy_appl x X(i) / ∑Yi2
for Biaxial
Where,
Ha_pile : Allowable horizontal pile capacity, Va_pile : Allowable vertical pile capacity
ΣH(i)x_appl, ΣH(i)y_appl : Total horizontal load, ΣV_appl : Total vertical load
N : Total number of piles
ΣMx_appl, ΣMy_appl : Applied bending moment about X and Y axis
X(i), Y(i) : Distance from X and Y axis to the farthest pile
∑Xi2
,∑Yi2
: Pile group moment of inertia about X and Y axis
c) Overturning Moment.
Overturning moments are those applied moments and shears that seek to cause the footing
to become unstable and turn over. Resisting moments are those moments that resist
overturning and seek to stabilize the footing. The overturning moment safety factor is the
sum of resisting moments divided by the sum of overturning moments. Safety factors defined
in the Setting of Constant criteria window. The Resisting moment is overturning moment from

the vertical forces such as applied loads, self weight and soil weight and overturning moment
resulting from the external applied shears and moments and the summation of all these
forces becomes the overall overturning moment at the edge of footing. The overturning
moment safety factor is calculated as the resisting moment divided by
overturning moment. Calculation of overturning moment is evaluated about all edges of the
footing in the service (=unfactored) load combinations for both X and Y directions.
d) Sliding Force
Considering ΣV and ΣH at the bottom of footing, it is obvious that ΣH will cause a tendency
for the foundation to slide at the bottom of footing, which is prevented by the friction that is
mobilized, the maximum value of which is ΣV(=summation of vertical forces) multiplied by the
coefficient of friction between the footing and the soil below. The sliding factor of safety
(=FS) against can be stated as follows; FS = ΣV x µ / ΣH. The maximum value of FS normally
specified is 1.5. For coarse-grained soils free from silt, µ may be taken as 0.55, while for
coarse-grained soils with silt the same may be taken as 0.45. For pure silt the value goes
down to 0.35. Calculation of sliding forces is evaluated at the bottom of footing in the service
(=unfactored) load combinations for both X and Y directions.
For additional sliding resistance you may enter and select the passive resistance of the soil,
also applies this value in the both directions.
e) Shear and Flexural Design (no shear reinforcing assume)
Self weight of concrete and overburden of soil normally do not include flexural and shear in
the footing because the footing is continuously supported by the soil beneath it. A buried
footing resting on a continuous soil bed. Typically it is not included in the design load
combinations but the self weight and overburden of soil automatically included in the service
load combinations.
The design codes available in AFES are as follows:
- ACI318, Building Code Requirements for Reinforced Concrete (USA)
- BS 8110 (1997), British Standard for Reinforced Concrete Design (England)
- IS 456 (2000), Plain and Reinforced Concrete-Code of Practice (Indian)
- KCI-USD99, Korean Concrete Institute of Concrete Design (Korea)
-KCI-USD2000 (SI Units) , Korean Concrete Institute of Concrete Design (Korea)
f) Flexural Design
In the footing design, the reinforcement required for a footing is computed based on the
resulting bending moments at the bottom of footing. In addition, selected reinforcing bars

and spacing are computed for the required reinforcing steel area based on the ranges of
rebar sizes and spacing specified by the user.
The flexural design of footing calculates the maximum moment and required steel for each
strip and for each design load combination. To select the required flexural reinforcing steel of
the footing, AFES considers moments at the face of the pedestal on all four sides.
The minimum reinforcing ratio calculates the design code for shrinkage and temperature
reinforcement. Strength reduction factor can be entered in the Setting of Constant window.
Proportioning the pile cap involves satisfying the one way shear and bending moment
requirements at the applicable critical sections in accordance with building concrete design
code.
g) Shear Design
One way shear (=Beam Action) in accordance with design code at distance of d or d/2 from
the face of pedestal in both directions. The d is the distance from the top of the footing to the
centerline of the reinforcing steel. The d distance value calculates as follows; Footing
thickness – the rebar cover – half the main bar diameter of the footing. The critical plane is
assumed to extend over the entire width or entire width per length of the footing. AFES
checks shear assuming only the concrete to resists the applied shear; the contribution of the
reinforcing steel to shear resistance is ignored.
h) Two Way Shear Design
Critical section for two way shear is perimeter (=bo), a distance d/2 or d from around the
supported member in accordance with design code.
i) Design of Piers
AFES can design the shear and reinforcement for the piers. For shear design in either
direction, AFES presents the required vertical and tie bar and spacing. Also given are the
concrete and steel contributions to resisting shear. The total factored load value is listed. For
flexure, AFES uses a rectangular stress block, and considers slenderness effects. AFES
presents the required vertical reinforcement assuming an equal distribution of bars. AFES
does not account for the development length required and the provided development length
for reinforcing if it is not hooked or bent into the footing.
2) Finite Element Method (FEM)
The AFES analysis is based on the hybrid finite element method with the thin plate modeling as footing.
Footings are automatically discretized into well formed quadrilateral and triangular elements at a

specified mesh size. Beams are automatically discretized. Soil response is achieved by employing non-
linear spring (=compressing only) supports to model subgrade reactions. Pile reactions, if present are
proportional to linear displacements of the supported node and include both compression and tension.
Also program calculates internal forces and deflections for all slabs and beams elements of the
foundation. This information is used in the design stage of the program.
The following is a list of the items included in the element stress output;
SQX, SQY : Shear stresses (Force / Unit length / Thickness)
MX, My : Bending moment per unit width (Moment / Unit length)
The element outputs are available at the center point of the element or all corner nodes of the element.
All element stress outputs are in the local coordinate system.

4. 7 Allowable Increase of Soil
1) Function
Soil subjected to short-term loads like wind and seismic can be increased in vertical capacity by certain
degrees. In consideration of this increase of soil bearing pressure, allowable increase soil factor can be
taken on the “Allowable Increase Factor of Soil menu. The factors usually can be out by geotechnical
studies and may be considered in the perspective of wind, earthquake and test load. To apply the
increased factors for design, they need to be set up in the dialog of load combination that will be
described later.

2) Command button
Note: As for short-term external force, allowable increase factor is prohibited as long as reduction
factors are already considered.
Ex) 0.75 x (1.4DL + 1.7LL + 1.7WL)
Typically accepted increase factors are as follows:
• LIBYA
Foundation subject to stresses produced by a combination of wind or earthquake loads with dead, live,
impact and vibration loads shall be proportioned for stresses 33% greater than basic allowable stresses
specified by the ACI code.
Allowable unit stresses for the design of foundations supporting process equipment may be 20%
during the hydrostatic testing of equipment, under static test load.
• TEXAS ABB
The allowable unit stress may be increased by 20%. Do not included earthquake combined with test
loads. Use 25%of wind load combined with test load.

4. 8 Allowable Increase of Pile
1) Function
As described in the previous chapter, increase factors of soil are explained an applied in design of soil
foundations. Likewise, pile foundations can have factors increased. These factors are related to
horizontal, vertical and uplift capacity. The factors typically give by geotechnical studies and may be
considered in the wind, earthquake and test load. To apply the increased factors for design, they need
to be set up in the section of Load Combination that will be described later.

To set supports condition parameters, click on the “Supports” tab in the setting of constant dialog
box. Soil foundations need to choose the “Elastic Mat” or “Plate Mat” options by clicking
Modulus of sub-grade reaction can be calculated by “Soil Support” button.

Click “Soil Support” to get the modulus. Enter or check appropriate values in the field displayed:
Allowable Soil Stress (qa), Long term, short term. Then click the “OK” button.
Note: See Joseph E. Bowels: Foundation Analysis and Design Page 503. The ks from allowable bearing
capacity furnished by the geotechnical consultant as follows;
Fps : ks = 12 x SF x qa kip/ft3
SI : ks = 40 x SF x qa kN/m3
Where SF=3.0(Long Term), 2.0(Short Term)
Qa= Allowable Bearing Capacity of Soil.
This equation is based on qa= qult/SF and ultimate soil pressure is at a settlement ∆H=0.0254m or 1
in.(1/12ft) and ks is qult/∆H. For ∆H =6,12,20mm,etc., the factor 40(ot12) can be adjusted to
160(or48), 83(or 24), 50(or 16), etc.; 40 is reasonably conservative but smaller assumed
displacements can always be used.
