Structural Engineering and Design in California
|
We
perform a variety of structural engineering
services for all types of
buildings including wood, steel,
concrete, masonry or tilt-up buildings,
new homes, renovations, extensions,
cottages, studios, guest houses, decks
and patios.
Our
structural design services are including
foundation plans with footing,
structural framing layouts with decking,
joist and trusses, roof trusses, ceiling
joists, and joist details, blown up
connection details and quantity
estimations with measurement sheets. |

Some sample guidelines for
structural plans followed by
Peyman Group
designers are:
CONCRETE AND MASONRY STRUCTURES
 Use a minimum concrete ultimate compressive
strength of 3000 psi at 28 days.
Specify size of aggregate and slump. Use
1-inch or ¾-inch minimum aggregate size, with
smaller sizes only in very special cases.
Avoid thin sections or projections that may
crack off when forms are removed. Chamfer column
corners, exposed corners and edges.
Provide typical construction joint locations
for concrete beams, joists and slabs.
Provide expansion joints, control joints and
seismic-movement joints as required by the
design, indicate their locations and details on
drawings and coordinate with architectural
enclosures and finishes.
|
Maintain a full depth of slab under
depressions for ceramic tile, electric ducts or
other construction.
Provide a typical column drawing indicating
bar maximum slopes, locations of splices and reglets for shear-wall reinforcing.
When setting a rail post use non-shrink grout
or equivalent (“Por-Rok” but not sulfur).
Provide a #4 bar on each side of post in
concrete.
If wood or steel studs are used in concrete
buildings, indicate clear relationship between
“face of concrete” and “face of studs”.
In masonry walls, base dimensions on modular
size of the unit.
In concrete masonry walls, fill all cells
except on free-standing site walls retaining no
earth. Avoid bars larger than Number 8.
Clearly show the minimum
concrete cover required for the intended fire
protection rating. |
|
|
|
STEEL STRUCTURES
Provide top-of-steel elevations at each column
and change of level on structural
drawings for ease of reference by steel
detailers and erectors.
For exterior steel work specify sections with
a thickness of ¼” or greater.
Indicate required camber on all tapered steel
girders and steel trusses.
Keep steel floor beams to L/D equal to or less
than 24.
|
Specify cost effective size, length and type
of welds. Use standard weld symbols and consider
fillet welds where adequate.
Make groove welds "full penetration" on
structural welds such as tapered girder flanges.
On welded assemblies to
be hot-dip galvanized, avoid shop
welding large areas, such as stair
platforms, to prevent warping in
galvanizing bath. Field weld and retouch
galvanizing, or use cadmium plated
counter-sunk flat head machine screws
for field assembly.
Provide means of leveling for base plates,
such as double nuts on anchor bolts.
|
|
Provide complete roof
framing plans showing walls. Clearly
indicate corner framing and slope of
roof.
Use nominal 6" wide
studs for walls with the exception of
non-bearing walls with no piping.
Clearly indicate
connection of vertical shear elements to
diaphragms. Be sure these shear elements
do not produce a high concentration of
stress over a small length.
Use minimum 1/2" thick
plywood for roof sheathing. Indicate
stagger of panels required for
horizontal diaphragms. |
