The LARSA 4D Difference

At LARSA, we've spent the last three decades leading the field of bridge engineering software with the latest computing technologies produced to the highest standards of quality. During this time we've developed a way of doing things that we call The LARSA 4D Difference.

It's about an unwavering commitment to all steps that go into the development of our software, and the ever-changing needs of the bridge engineering community supported by LARSA's staff of engineers and researchers that are highly specialized, yet very collaborative. But most of all it's about our commitment to deliver the highest degree of customer satisfaction to our clients, who believe there's a better way of doing things.


LARSA 4D Version 8.01.14

LARSA 4D 8.01.14 is the latest release in the LARSA 4D 8.01 Series. LARSA 4D Series 8.01 delivers significant new features including AASHTO LRFD code check for shear studs in I-girder bridges for Fatigue Limit and Strength Limit States, Vehicle Track Structure Interaction (VTSI) Analysis for high-speed rail bridges with car dynamics, and more.
