Cross Frame Code Check (AASHTO) [PIG]
General
Cross Frame: Cross frame for code check
Code Check Template: The code check template is utilized to extract global parameters, results from finite element analysis, and limit states employed in the design process.
Straight/Curved[Straight Bridge/Curved Bridge]: This parameter defines the bridge type.
PDF Name (Export): This parameter allows the name of the code check document to be modified when saving it as a PDF. When renaming the file, special attention must be given to the text characters on the linked page, as certain characters may interfere with parametric equations and lead to unexpected results.
Shear Lag Factor
To perform fatigue and tension fracture check calculations per AASHTO 9th Edition (Condition 7.2, Table 6.6.1.2.3-1 and 6.8.2.2), inputs for connection eccentricity and the maximum length of longitudinal welds are required. Therefore, the effective area can be determined by the formula Aeff = (1-x/L)Ag where x represents the connection eccentricity, L is the maximum length of the longitudinal welds and Ag denotes the gross area of the section.
These parameters, connection eccentricity (x) and maximum length of longitudinal welds (L), can be separately specified for the top chord, bottom chord, and diagonal chord.
Top Chord Connection Eccentricity: Specify the connection eccentricity (x) for top chord.
Top Chord Max Length of the Longitudinal Welds: Specify the maximum length of the longitudinal welds (L) for top chord.
Bottom Chord Connection Eccentricity: Specify the connection eccentricity (x) for bottom chord.
Bottom Chord Max Length of the Longitudinal Welds: Specify the maximum length of the longitudinal welds (L) for bottom chord.
Diagonal Chord Connection Eccentricity: Specify the connection eccentricity (x) for diagonal chord.
Diagonal Chord Max Length of the Longitudinal Welds: Specify the maximum length of the longitudinal welds (L) for diagonal chord.
Vertical Strut Connection Eccentricity: Specify the connection eccentricity (x) for vertical strut.
Vertical Strut Max Length of the Longitudinal Welds: Specify the maximum length of the longitudinal welds (L) for vertical strut.
