LARSA 2000's makes modeling structures and accessing results easier than ever. The front-end has been entirely redesigned since the previous version of LARSA to improve performance, usability, and power.
In 1986, LARSA expanded its engine to meet the needs of any structural analysis that a practicing engineer might find at that time, including seismic analysis and design. At the same time, a graphical user interface was released for DOS. LARSA was the first to offer an individual PC-based DOS structural analysis package with geometric nonlinear analysis capabilities.
LARSA again led the industry in 1994 by taking the next step to Microsoft Windows. That year LARSA introduced its 16-bit Windows 3.x version of the software with a point and click graphical user interface. In 1996, LARSA was the first to offer elastic/perfectly plastic pushover analysis.
In 2001, LARSA released the 6th version of its product, LARSA 2000/4th Dimension, with an all-new, powerful user interface and an engine with unmatched analytical features. LARSA was again the first software in its class to offer Sparse Solver technology, which decreased analysis time by a factor of 30. New analytical features included influence line based moving load analysis, staged construction analysis, time dependent construction analysis, hysteretic and seismic elements, and progressive collapse. LARSA 2000/4D eliminates the need for engineers to use specialized software for each aspect of a project by integrating many analysis types into one comprehensive, multipurpose program.
