ATENA Supports Engineers in Using Modern Methods for Seismic AssessmentPushover analysis enables engineers to quantify the real structural behaviour taking into account the nonlinear effects such as cracking, reinforcement yielding, etc. At the same time this method still preserves reasonable computational cost compared to full dynamic nonlinear analysis. This method is also favoured by engineers due to its relative simplicity, and because it nicely works with the standard definition of the seismic loading by elastic response spectra. In the last year, ATENA has been used successfully in several projects involving seismic assessment of existing safety critical structures from nuclear industry. The following figures show the main results from a pushover analysis of a reinforced concrete nuclear shielding structure and a full scale analysis of a reinforced concrete frame building, which houses the control room of a nuclear power plant. |
