Simulation of large dimensional reinforced and prestressed concrete structures using a new adaptive static condensation method including automatic mesh partitioning

In order to evaluate the cracking process in large reinforced and pre-stressed concrete structures, a predictive simulation of damage with refined mesh nonlinear law is required. Because computational load, such modelling not applicable directly on large-scale structures whose characteristic dimensions are over several tens meters. To deal this type structure, an adaptive static condensation method (ASC), which concentrates effort damaged area (domain interest) only, proposed. The ASC first presented. A particular attention paid needed developments extend its domain application up prestressed structures. then applied three point bending beam validated by comparison classical finite element computation. numerical efficiency proposed approach evaluated with, application, time saving factor about 15. An automatic partitioning implemented make even more efficient. Based physical considerations, it takes into account expected shape evolution regions during loading. It test cases different geometries loading discuss calibration through sensitivity analysis. unique set parameters finally demonstrated. As conclusion; complete made available for scale
