Research of Maintenance Decision-Making about Existing Building Structure Based on the Life-Cycle Cost Theory

The project is a complicated systems engineering. The theory of whole life cycle cost considers roundly each phase of the project such as design. life cycle cost theory is applied to fields of maintenance and reinforcement about existing building structure, modeling with a reinforced concrete frame structure deterioration, it made a research about the influence of maintenance, repair and reinforcement measures to the reliability and deterioration speed of existing structure while analyzing its life cycle cost, considering economic optimization problem so as to select economy and reasonable maintenance scheme from multiple plans.
