bridge

Bridge

defines moving load (based on SAPFIR), generates influence surfaces

dynamic

Time history analysis

simulates the process of dynamic loading according to accelerograms, determines forces and displacements at certain time periods, takes into account damping structures and material damping

km

KM-SAPR

automatically generates working drawings KM (of steel structures) – tagged models, joints, specifications (only in Russian)

soil

Soil

generates 3D model of the soil based on engineering & geological surveys (geological boreholes) and applies generated model further in analysis of the ‘overground structure – foundation – soil’ system

meteor

METEOR system
