Material Time Effects

Critical for the design and analysis of segmental concrete bridges, time-dependent material properties can be utilized within LARSA's 4D Staged Construction Analysis.

LARSA's time-dependent material effects take into consideration the following properties:

Creep and shrinkage of concrete

Relaxation of steel

Time effect on the modulus of elasticity of concrete

Tendon (pre-/post-tensioning) losses from creep, shrinkage, relaxation, and superimposed loads

Custom time-dependent material curves for particular material properties and codes

Supported Codes

LARSA's time-dependent material effects work with the following supported codes: AASHTO LRFD 2010, CEB-FIP '78 and '90, AS3600-2009 Australian Codes, and EN 1992-1-1:2004 Eurocode 2.
