About this file
This is a seismic joint plan drawing for the Portland International Airport (PDX) Terminal Upper Roadway Joint Replacement project in Portland, Oregon. The drawing, dated October 2026 and prepared by architectural and engineering firm PDX (located at 111 SW Fifth Ave., Suite 2600, Portland, OR), provides detailed specifications for seismic joint movements and structural joint widths across multiple joints numbered 5 through 38 within the enplaning roadway. The plan illustrates service movements, code minimum movements, and vertical movements for parallel and transverse directions, with service movements calculated based on thermal considerations using a ±35-degree temperature change from nominal conditions. The drawing includes references to existing structures from various years (1973 through 2021) and specifies joint movement requirements in inches, ranging from 1/8" to 5" parallel movements and up to 3" transverse movements. The document is marked as a progress print digitally signed on June 30, 2026, and reflects design standards for seismic joint performance at the CD terminal upper roadway.
The drawing notes indicate that code minimum movements are based on the Square Root Sum of Squares (SRSS) of BSE-1N movements for new construction, with provisions that existing joints satisfying current movement parameters meet code requirements. Vertical movements are derived from expected foundation liquefaction settlements as detailed in the project's geotechnical report, calculated using the BSE-2N seismic event with final condition foundation loading. The plan provides a graphical scale reference and notes that drawing scale is reduced 50% for 11" x 17" sheet sizes. The document serves as a technical specification sheet for the joint replacement project, ensuring structural compliance with seismic safety requirements specific to Portland International Airport's terminal roadway infrastructure.

SEISMIC JOINT NOTE(S):
1. CODE MINIMUM MOVEMENTS ARE BASED ON THE FOLLOWING.
SQUARE ROOT SUM OF SQUARES (SRSS) OF BSE-1N MOVEMENTS OF
EACH SIDE. THIS IS THE CODE MINIMUM FOR NEW CONSTRUCTION.
FOR EXISTING JOINTS IF THE EXISTING MOVEMENT IS NOT INCREASED
THE EXISTING JOINT SATISFIES THE CODE REQUIREMENTS.
2. SERVICE MOVEMENTS ARE BASED ON THE FOLLOWING: SQUARE
ROOT SUM OF SQUEARS (SRSS) OF THE THERMAL MOVEMENT
CONSIDERING A +/-35DEG TEMPERATURE CHANGE FROM NOMINAL OF
EACH STRUCTURE.
3. SEISMIC JOINT MOVEMENTS ARE NET STRUCTURAL MOVEMENTS OF
TWO SIDES OF SLAB MOVING RELATIVE TO EACH OTHER FROM THEIR
AT REST POSITION. SEE FIGURE 1.
4. VERTICAL MOVEMENTS ARE BASED ON THE EXPECTED FOUNDATION
LIQUIFACTION SETTLEMENTS IN THE PROJECT GEOTECHNICAL
REPORT BASED ON THE BSE-2N EVENT WITH THE FOUNDATION
LOADING FROM THE FINAL CONDITION USING THE SEISMIC LOAD
COMBINATION.
