Jay Ryan R. Santos has experience designing various types of industrial structures including pipe racks, equipment structures, shelters, table tops, modular structures, vessel foundations, tank foundations, and mining equipment foundations. He has expertise in load calculations, steel and concrete design, lifting analysis, transportation analysis, and seismic analysis of industrial structures.

2. My Work
Pipe Rack and Pipe
Bridge- Both Modular
and Stick Built
Load Calculation of
Pipe Racks using:
• ASCE 7-05
• API Standards
• PIP (Process Industry
Process) loadings
• Eurocode SC1
Steel and Concrete
Design for Members
and Connections
using:
•AISC 13th Ed. (ANSI/
AISC 360-05 – Low
Seismic Application, R
≤3)
•AISC 13th Ed. (ANSI/
341– High Seismic
Application, R >3)
•Eurocode SC2
(Concrete)
•Eurocode SC3 (Steel)

3. My EPC Work
Equipment Structures -
Both Modular and Stick
Built
Equipment Structure:
•Same Loading as for the
pipes in a Pipe rack with
additional loadings from
stairs, platform, and
equipment.
•Equipment Structures
have been modeled
together with the equipment
Center of Gravity (COG).
•Seismic Computation
using Dynamic Analysis is
prepare especially if the
weight of all non-building
structure is greater than or
equal to 25% of non-
building structure plus
supporting structure.
•Modal Response
Spectrum Analysis has
been the method of choice
for computation of effective
seismic weights. The
analysis shall include a
sufficient number of modes
to obtain a combined modal
mass participation of at
least 90 percent of the
actual mass in each of the
orthogonal directions of
response considered by the
model.

4. My EPC Work
Shelter Structure:
•Shelter Structures
are structures in
which personnel
stay longer and thus
needs to be
designed just like a
building structure.
•Additional
provision for gantry
crane loading must
be considered in the
design. In which
impact load must be
consider.
•Slope of the roof
must be considered
for calculation of
wind loads and
snow loads (if
applicable).
•Monorail design
shall be included (if
applicable).

5. My EPC Work
Table Top
Table Top:
•Table Top is a
RC structure in
which an
Elevated Top
Slab supports
equipment.
•Modeled with
soil spring and
damping
constants for
realistic
calculation of
frequencies.
•Limits of
Displacements
usually govern
the thickness of
the Top Slab.
•Modal
Participation is
usually the

6. My EPC Work
Modular
Structures
Lifting Analysis:
•Modeling of slings
•Input of correct
stiffness of sling
must be accounted.
•Additional Dynamic
Amplification that
ranges from 1.35 to
2.00 needed for
members directly
connected to lift
points and
members not
directly connected
to lift points.
•60/40 and 40/60
load distribution
must be considered.
•Design of Lifting
Lug/ Padeye

7. My EPC Work
Land
Transportation
Analysis:
•Realistic Modeling
of structure together
with transportation
module.
•Arrive at the best
structural
configuration which
gives enough
strength and
stiffness, and
minimum
deflections of
structure as well as
of transportation
beam (commonly
known as
RTV/SPMT).
•Uses of springs
and rigid links for
modeling.

8. My EPC Work Experiences
Water
Transportation
Analysis:
•Calculation of
wave induced
acceleration:
pitch, roll, heave,
head sea, beam
sea,
port/starboard,
and bow/stern.
•Allowable Loads
on Decks must
be considered.
•For long duration
of transportation,
fatigue analysis is
necessary.

9. My EPC Work Experiences
Vertical Vessel
Foundations:
•Because of large
load Moment on top
of pier, Vertical
Vessel Foundations
on soils or on piles
are designed with
Octagon Pier. This
geometry optimizes
Pier Vertical Rebars
for Additional Tension
Reinforcement for
Anchor Bolts.
•If still Pier Vertical
Bars are not enough,
especially for tall and
lightweight vessel,
hairpins can be use.
•For realistic
calculation of period
used for seismic and
sometimes wind
design, can be
modeled as a stick
cantilever with
various diameter.

10. My EPC Work
Storage Tank
Foundations:
•Large Storage Tank
Foundations are usually
ring wall foundation.
•Regions of low seismicity
or in seismic areas where
the tank diameter to height
ratio is such that there is no
uplift of the tank shell or
small sloshing effect. The
magnitude of lateral forces,
overturning moments, and
associated hydrodynamic
mass be determined to
assess their impact on tank
shell and foundation
design.
•A concrete leveling ring
can be used under the tank
shell in the gravel ring wall
foundation. Additional
advantages of the leveling
ring are to distribute
concentrated shell loads on
to the gravel ring wall and
minimize edge settlement
under seismic condition.

11. My EPC Work
Horizontal Vessel
and Heat
Exchanger
Foundations:
•Distribution of
Loads for Fix and
Sliding Side of the
Pier will depend on
the vessel CG.
•Thermal Load will
be equal to the
minimum between
thermal friction and
half the force
needed to deflect
pedestal.
•Steel Sliding plate
is usually used for
lightweight
horizontal vessels.
For heavy
equipments, Teflon
can use with low
coefficient of friction
for economical
foundation design.

12. My EPC Work
Silo
Foundations:
•Design of Silo
and Storage
tank by API 650.
•Seismic Design
Loads is the
Square of the
Sum of
convective and
impulsive
behavior of its
content.
•Wind Load
during Empty
sometimes
governs in its
foundation
