Risk Analysis of Super Long-Term Maintenance Process of Rc Building Group Based on Damage of the Virtual Earthquake

Abstract

Corrosion process of reinforcements of RC building group based on super long-term combined deterioration is integrated into the seismic assessment and changes of human and building damage in virtual earthquakes causing one fatality at the new condition are analyzed. The number of fatalities in the group with maintenance and deterioration by the scenario oriented for Economy does not change for 200 years, but maintenance could not eradicate the increase of severely injured people and completely collapsed buildings. Risk of buildings in super long-term should be reviewed for the group unit stochastically because of the uncertainty of seismic performance.
