Cross Frame Code Check (AASHTO) [SIG]

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.

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 A_eff = (1-x/L)A_g where x represents the connection eccentricity, L is the maximum length of the longitudinal welds and A_g denotes the gross area of the section.

Connection eccentricity (x) and Maximum length of longitudinal welds (L)

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.
