ALUMINUM STRUCTURE VERIFICATION - AA ADM-2015
The Aluminum verification module allows to compute the resistance and limit states for the aluminum elements in the model. The calculations of the elements resistance is performed according to the AA-ADM-2015 standard.
The program allows to perform verifications such as Compression, Tension, Bending, Compression-Bending, Tension-bending, Shear, Torsion and Warping.
COMPRESSION
The compressive resistance (Cr) of a member is calculated according to clauses 9.4.1, 9.4.2 and 9.4.3. The slenderness of the plates is determined according to clauses 8.2.1, 8.2.2, 8.3.1, 8.3.2 and 10.2.1.
The torsional buckling stress is calculated using the method presented in clause 13.3.2 of the CAN/CSA S16 code from where the equations of clauses 9.4.3.2 and 9.4.3.3 of the CAN/CSA-S157 code are taken (see commentary C9.4.3.3).
The compressive resistance of a built-up section is calculated according to clause 9.8.2.
The torsional buckling stress is calculated using the method presented in clause 13.3.2 of the CAN/CSA S16 code from where the equations of clauses 9.4.3.2 and 9.4.3.3 of the CAN/CSA-S157 code are taken (see commentary C9.4.3.3).
The compressive resistance of a built-up section is calculated according to clause 9.8.2.
BENDING
The bending resistance (Mr) of a member is calculated according to clauses 9.5.2 (resistance of the cross section) and 9.5.3 (lateral torsional buckling). The slenderness of the plates is determined according to clauses 8.2.1, 8.2.2, 8.3.1, 8.3.2 and 10.2.1.
The lateral torsional buckling resistance is calculated using the general lateral torsional buckling equation. The equation presented in clause 9.5.3.2 is a simplification of this general equation.
The lateral torsional buckling resistance is calculated using the general lateral torsional buckling equation. The equation presented in clause 9.5.3.2 is a simplification of this general equation.
ALUMINUM VERIFICATION
The program calculates the bending, compression, tension, shear and combined resistance of aluminum based on the results of a linear, P-Delta, non-linear, seismic, dynamic or moving load analysis. Singly symmetric, asymmetric and built-up section shapes are covered for all design codes.

WELDS
The welds have an important influence on the resistance of aluminum elements. The program distinguishes two types of welds which are end welds and in-span welds. Each of these types of welds may be full (affecting the entire cross section) or partial (affecting a portion of the cross section).
In the case of full welds, the ratios of welded area (Aw/Ag) are considered equal to 1.0.
In the case of partial welds, the ratio of welded area for each flat segment must be specified. Partial weld ratios on each segment are used in the calculation of the critical local buckling stresses of flat and curved segments in compression.
