Study on variable action value standard for harbor infrastructures

To meet with different levels of requirements from proprietors and users and to offer a basis for variable action value to the designers, associated with the standards, this dissertation studied the value standard of load effect and environmental effect. For load effect, on the foundation of analyzing variable load effect model, we used equal exceeding probability principle to calculate the load adjustment coefficient for the cargo loading in harbor and river port under different designing service life. For environmental effect, according to the ranks of marine chloride environment in standards GB/T 50476-2008, after analyzing and comparing the research achievements on surface chloride concentration at home and abroad, we obtained the value standard of chloride ion loading in different ranks of chloride environment. © 2014 4th International Conference on the Durability of Concrete Structures.
