Floor Beam Live Load moment calculation in LARS
I'm doing a rating of a Girder-Floorbeam-Stringer bridge in LARS (LFR). I hardcoded the input files to automatically create check points at section changes '[SectionChangeGenerateCheckPoints] 1', and that appears to work fine except for with the floor…
LARS Bridge Floorbeam Checkpoints
Looking at LARS Bridge Report Type "Detail - All Checkpoints" for floorbeams, the "Flexural Member Report" only displays the critical checkpoint locations (i.e. I am seeing only 2 checkpoints in the report; 1 for controlling moment & 1 for controlling…
LEAP Bridge Substructure/RC-Pier LFD Live Loads in the Negative Moment Region
I am using the LEAP Bridge Substructure module to design a pier for a continuous 4 span structure using HS20 LFD loads.
In the AASHTO Standard Specifications, it gives you a few options for the loading. One is that you can use a lane load with one concentrated…

LARS LRFR NonComposite Steel Report Information
LARS checks the compression flange and tension for top and bottom for each checkpoint. This is performed because any checkpoint along a beam may be the location at which contraflexure occurs. When the…
Re: LARS Composite Beam Rating - LFD
LARS steel sections properties are usually the same as many programs.
If the Description/Analysis Codes/LFD Moment Redistribution option is checked, LARS will perform the moment redistribution as specified in AASHTO Standard Specification 10.48.1.3…
