STRUCTURAL ANALYSIS
Ramp System Design Criteria and Analysis
1) Reference Design Criteria:
a) International Building Code, 2021 Edition, ASCE 7-16, 51-50 WAC
2) Site Specific Criteria:
a) Building Occupancy Classifications: II
b) Vertical Loading: 100 psf for Landings, 300 lbs. concentrated loads
c) Horizontal Loading:
i) Wind Loads: 135 mph(ultimate), Exposure B, Kz=0.85, Kzt=1.0; Design
Wind Pressure = 30 psf (At less than 15 feet above grade,
IBC 2021, 1609.6.2) w/ 5' effective width = 30 Ibs/leg
ii) Seismic Loads: Sds = 1.50, S1=0.50, 1=1.0, R=3.25, Qo=2, Cd=3.25, Cs=0.462,
w/62.5#DL/leg*0.462*2 = 58#/leg
iii) Pedestrian Traffic Load: 5'effective*100psf*1/12*1.5 = 63#/leg
d) Soil Bearing: 1,500 psf, unless verified by Geotechnical Report or Building
Official
3) Material Specifications:
a)
Aluminum:
i) Handrail
ASTM 6063-T5, 16 ksi, minimum yield strength
ii) Structural
ASTM 6061-T5, 35 ksi, minimum yield strength
b)
Density
170 Ibs. per cubic foot
c)
Yield
10,000 ksi.
4) Connectors:
a)
Bolts
Grade 5 zinc -coated (Design), ASTM A-325 may be substituted.
b)
Screws
#10x1.25" zinc plated Self -Tapping Screw (STS)
c)
Welding
Per AWS D1.2 and size as shown on the drawings
d)
Sleeves
Length of snug -fitting sleeves designed resist moment and
shear of sleeved connection.
5) Design Basis:
a) Each side of the assembly is a framed made rigid by either welding or assembling parts together
in sleeves to resist movement. Base connections are a pinned condition.
b) Each frame is connected together with landing or ramp frames and planking to distribute dead
and live loads to the frames. Railing is added to the frame assembly.
c) Landing Platforms are attached to buildings with Lag -bolts or SDS Screws.
d) Basic Dead Load is 5 psf for frame, ramp & landing surfaces. 2 psf is added for railing.
WELCOME RAMP CALCS-IBC 2021, 51-50 WAC Page 2
e) A 300 lb. lateral load is used in the design to simulate seismic, wind and pedestrian lateral
loading for each frame (2 frames per unit, 600# per assembly). This results in an effective Design
Cs for a 30-foot ramp and 5x10 platform of 0.5 and a design wind load of 30 psf without
consideration for stress duration. Seismic and wind loads do not govern lateral loading for
standard configurations. Standard platform lateral loading will be resisted by connections of
platform to building. (3) SDS25300 (OR 3/8"0 x 3" lag -bolts= 900# for each 5' platform section.
Lateral loads of ramps and stair assemblies attached to the platforms will be resisted by the
platforms.
f) Anchorage for Asphalt and Concrete Substrate: Where requested by the Owner, anchorage of
ramps and stairs to asphalt and concrete substrates will be done with drilled anchors. Asphalt
substrate conditions will use (1) 'Bolt -Hold' SP-10 at each bottom bearing plate of last section of
ramp and bottom of stair. Concrete substrate conditions will use (1) 'Simpson' Titen HD
YV 00".

Member Stress Results
Access the Member Section Stresses spreadsheet by selecting the Results menu and then selecting Members •
Stresses.
These are the member stresses calculated along each grft� member. The number of sections for which stresses are
reported is controlled by the Number Of Sections specified on the Global window The actual number of segments is
this Number Of Sections minus 1. The incremental length of each segment is the same. For example, if you specify 5
sections, the member is divided into 4 equal pieces, and the stresses are reported for each piece.
There will be four stress values listed for each section location along the member taking into account any inernber
offsets The units for the stresses are shown at the top of each column. As for the sign convention, the signs of these
results correspond to the signs of the forces. These line up as positive or negative according to the member local axis
directions.
The axial stress is the ratio P/A, where P is the section axial force. A positive stress is compressive, since the sign of
the stress follows the sign of the force-
The shear stress is calculated as V/S.A., where S-A. is the effective shear area For members not defined with a section
set a value of 1.2 is used for the shear area coefficient S.A.
The bending stresses are calculated using the familiar equation M • c / I, where'M" is the beading rnornent, "c" is the
distance from the neutral axis to the extreme fiber and "I" is the moment of inertia. The stress for the section's extreme
edge is listed with respect to the positive and negative directions of the local v and a a„3=. A positive stress is
compressive and a negative stress is tensile.
Some shapes are not symmetrical about both local axes. For example Tee and Channel shapes. Thus the stress at the
positive and negative edges may not be the same. The locations for the calculated stresses are illustrated in this
diagram:
Y Bend Top Bend Top

THend Bot Bend Bet
Y Bend Top Y Bend Top

Bend Bot Bend got
So, the y-top location is the extreme fiber of the shape in the positive local y direction, y-bot is the extreme fiber in the
negative local y direction, etc. The y-top,bot stresses are calculated using Mz.
For enveloped results the maximum and minimum value at each location is listed. The load combination producing the
maximum or minimum is also listed, in the "W column. To include a particular Load Comhinatinn in the envelope
analysis, open the Load Combinations spreadsheet and check the box in the "Env" column.
Note
A special case is bending stress calculations for single angles. The bending stresses for srYla angles, are reported
for bending about the principal axes.
To view the results for a particular member, use the Find option. To view the maximums and minimums, use the Sort
option.

Calculation Procedure
t) Closed Shapes:
The geometric properties for closed shapes are computed by using the Polygon method.
All closed shapes are represented by closed polygons. Curvilinear and circular shapes or
edges are represented by several straight line segments. The properties the overall shape
are computed by geometric summation of the properties of a trapezoid defined by
projection of two consecutive points of the cross-section on to the x and y axis.
2) Open Shapes:
The geometric properties for open (thin walled) shapes are computed by using the Polyline
method. All open shapes are represented by polylines. Curvilinear and circular shapes or
edges are represented by several straight line segments. The properties the overall shape
are computed by geometric summation of the properties of a line defined by projection of
two consecutive points of the cross-section on to the x and y axis
