Transverse Live Load On FELines [FEA]

Applies a transverse live load across a set of finite-element lines, positioning wheel loads and lane loads to produce the governing transverse effect. Multiple presence factors are applied according to the number of loaded lanes.

Inputs

FELines: The finite-element lines the transverse live load is applied to.

Stage: Construction stage at which the live load is applied.

Axle Load: Magnitude of a single wheel/axle load (default: 16).

Lane Load: Uniformly distributed lane load applied alongside the axle loads (default: 0).

Max. number of lanes[1 Lane=0/2 Lane=1/3 Lane=2/4 or More=3/No Limit=-1]: Caps how many loaded lanes are considered when searching for the governing arrangement. No Limit lets the search use as many lanes as fit (default: No Limit=-1).

Multiple Presence Factors: Multiple presence factors applied by number of loaded lanes, in order (default: 1.2, 1, 0.85, 0.6, 0.6).

Distance between Wheels: Transverse spacing between the two wheels of an axle (default: 72).

Minimum Distance between Vehicles: Minimum transverse clear distance enforced between adjacent vehicles (default: 24).

Alignment Direction[X-Direction=0/Y-Direction=1]: Global axis the alignment runs along, which fixes the transverse direction the load is swept in (default: Y-Direction=1).

Unit Load Spacing: Transverse increment the load pattern is stepped by while searching for the governing position (default: 36).
