LARSA 4D Introductory Tutorial Part 1: In this Introductory Tutorial for Bridge Projects we’ll use LARSA 4D’s BRIDGE Series software to provide an overview for the analysis of a straight, two-span, single girder bridge with a T-shaped cross section.
LARSA 4D Introductory Tutorial Part 2:In video we’ll assign the material and cross-section properties for our LARSA 4D bridge model.
LARSA 4D Introductory Tutorial Part 3:In this video we’ll define joints, members, and abutment bearings to lay out the geometry of our bridge model along the global x-axis.
LARSA 4D Introductory Tutorial Part 4:This video creates a static load case for Self-Weight only using LARSA 4D’s Load Cases explorer, then computes the effects of Self-Weight on the load case using a Linear Static analysis.
LARSA 4D Introductory Tutorial Part 5:Influence line and surface analysis is an extension of the moving load analysis which uses the effects of a unit load to rapidly compute the effects of arbitrary complex load patterns on design lanes.
LARSA 4D Introductory Tutorial Part 6:LARSA 4D’s Staged Construction Analysis models changes to the structure over time. In this last video we’ll create a basic set up for staged construction using construction and loading activities.
LARSA 4D Steel Bridge Module Features: Available in LARSA 4D BRIDGE Series packages, LARSA’s Steel Bridge module features a fully integrated code check supporting AASHTO LRFD design code, allowing our users to optimize the design for safer bridges while saving time, and reducing cost through the use of a single software that permits refined analysis and detailed code check.
LARSA 4D Steel Bridge Module
– In Part A: Model Generation, the module collects the needed structural information in order to generate a 3D finite element representation of the bridge. This task defines the general structure information including geometry, girder type, section, and material.
– In Part B: Bridge Loading, the Steel Bridge Module generates load cases, staged construction information, and post analysis result cases including linear result combinations, extreme effect groups, and influence result cases according to AASHTO LRFD design code.
– In Part C: Code Check, we review how to map load classes and define the locations where the Steel Bridge Module will perform AASHTO LRFD code check.
