    AT THE HEART OF LARSA 4D
    At the core of LARSA 4D's BRIDGE SERIES Software, staged construction analysis models the changes
    to a structure over time with construction activities and time-dependent material effects, such as creep and shrinkage.

LARSA 4D Staged Construction Analysis

Staged construction analysis provides an integrated environment in which to model the changing state of a structure over time, including structural changes, load applications, concrete and composite activities, and time-dependent material effects

Load Class Tracking

Essential for the design and code check of AASHTO compliant structures, Load Class Tracking allows each construction activity to be associated with a load class such as "dead load", "live load", or "prestress", so that the cumulative effects of load classes can be reported separately for code-based load combinations. In LARSA 4D, load class tracking of construction activities such as support changes and element removal provide an accurate portrayal of nonlinear force redistribution in the structure.

Segmental Construction

The segmental construction options for Staged Construction Analysis are used for modeling balanced cantilever bridges. The hinged cast, matched cast, and displacement initialization options automatically adjust bridge geometry as new segments are cast to match the displacements of previous segments.

Construction Activities

Construction activities in LARSA 4D include construction and deconstruction of members, plates, springs and foundations, in addition to loading, temporary/traveler loads, support changes, displacement initialization and hoist for incremental launching.

Staged Construction With Incremental Launching

Analysis within Stage Construction

Nonlinear time history and eigenvalue analysis can be included within any stage of a construction analysis, in which results are based on the deformed and stressed state of the bridge at any point during the construction sequence.

Construction/Deconstrucion

LARSA's powerful staged construction analysis engine with geometric and material nonlinearity captures the unique behaviors of erection and deconstruction in real-time, as defined through the steps and stages of the project's construction sequence.

Analysis Options

In LARSA 4D, staged construction analysis takes into account advanced features for the effects of geometric and material nonlinearity, as well as time-dependent material effects within the same analysis run to capture results with unprecedented accuracy.

At the heart of LARSA 4D, staged construction analysis is included in the following LARSA 4D BRIDGE SERIES packages.
