Pushover analysis – Strengthening and repair of buildings according to EN1998-3
Fespa 10 is equipped with the add on module (Fespa 10R) which performs repair and strengthening of existing reinforced concrete buildings and evaluation of the seismic performance of a new building.
The engineer describes the reinforcement arrangement at beam and column ends of the existing building, using the relative properties and commands.
Furthermore, using the appropriate set of commands and properties the user can describe column cross-sections of arbitrary shape and their reinforcement model.
The moment-chord rotation diagrams of beams and columns are developed, for the assigned reinforcement arrangements (moment-chord rotation diagrams can also be developed for steel members).
After the pushover analysis, the Acceleration Displacement Response Spectrum (ADRS) is generated and displayed in 3DV. The target displacement is calculated for up to three discreet accelerations and limit states.
The capacity ratios, for all members, are derived for every limit state.
