Abstract

A building materials durability model has been developed using a framework that encompasses environmental stimuli, material degradation, structural performance criteria, and maintenance strategies. The model takes a global viewpoint, rather than a microscopic focus, to produce predictions of life-cycle costs of building materials for structural applications. The model is completely general and capable of either simple or complex simulations depending upon the sophistication of the damage models used, the repair strategies considered, and the economic conditions assumed. The current study applies the model to a simple beam to compare painted structural steel and reinforced concrete in different climates and economic environments. The life-cycle cost model allows the engineer to compare the economics of two candidate materials for a given application, assess the consequences of repair strategy, compare durability of a material in different environments, and choose the best durability strategy for short- and long-term applications.
