About this file
This document is a structural engineering calculation and site plan for a Post Frame Building Structural Calculation prepared by Alliance Engineering of Oregon, Inc. for Clackamas County Facilities Management, located at 9324 S. Wildcat Road in Molalla, Oregon. The project involves constructing a proposed Sand Shed on a 5-acre property (217,815 square feet), with the structural design focusing on a 60x100x9 foot building that includes a main building and shed areas. The engineering calculations comprehensively analyze wind loads, seismic considerations, snow load requirements, and structural member design using the 2022 Oregon Structural Specialty Code and various engineering standards.
The site plan and structural analysis detail precise engineering specifications, including wind speed (98 mph), exposure conditions, roof snow load calculations, and seismic design category (Category D). The building is designed to withstand complex loading scenarios, including dead loads, live loads, wind loads, and potential sand storage loads. Key design parameters include a ground snow load of 25 psf, wind exposure factors, and specific structural member calculations for posts, rafters, and foundations. The engineering document meticulously evaluates load combinations, stress ratios, and structural integrity under various potential environmental and usage conditions, ensuring the proposed Sand Shed meets rigorous structural and safety standards.

EMBEDMENT FOR SHED EAVE POST:
Calculate the minimum required post embedment depth for lateral loading for the shed posts.
Post_is "not constrained by a concrete slab"=
Va 2692 lb= Lateral shear load at the ground line
Ma 21620 lb ft= Moment at the ground line dia_Sfooting 2.00 ft= Shed posthole diameter
Ssoil 100 psf= Lateral capacity of soil
Trial depth = 1.5 ft.- The starting depth of the post hole depth. The final post hole depth is determined by iterating to a final depth.
depth_post 4.66 ft= This is the minimum required post embedment depth for lateral loading
FOOTING DESIGN FOR SHED EAVE POST:
Determine the footing size and depth for vertical bearing for the shed posts.
qsoil 1500 psf= Soil bearing capacity for footing dia_Sfooting 2.0 ft= Footing diameter
ASfooting π dia_Sfooting
:= ASfooting 3.14 ft2= Footing area
SPost_depth 5.5 ft= Minimum required post embedment depth
PSftg_allow ASfooting qsoil dfactor:= PSftg_allow 9425 lb= Allowable end bearing capacity of footing pSftg_applied 5962 lb= Total applied footing load
Note that the end bearing capacity (PSftg_allow) is greater than the combined footing load (pSftg_applied). This is OK.
Next, check main eave post uplift:
SPul Wshed
OverhangS+
Bay 0.6 quplift( ):= SPul 1915 lb= This is the uplift on one shed post
Assume a total weight of roof area to be 0.6*Dead Load (pd). The area of the roof that will tend to keep the shed post in the ground will be as follows:
SEpost_hole 150 pcf SPost_depth π dia_Sfooting
Apost-
:= SEpost_hole 2133 lb= Weight of concrete in post hole
SWulr Wshed
Bay 0.6 pd( ) SEpost_hole+:=
SWulr 2718 lb= Total uplift resistance
Note that the total uplift resistance (SWulr) is greater than the uplift load (SPul). This is OK.
