Abstract:
Based on carbonization experiments of 6 rectangular,2 T-type and 2 Π-type concrete beams accelerated by wind, combining existing testing data, some primary advices were put forward about equal durability design of concrete bridge structure influenced by wind in natural wind environment. Analytical results show that the concrete carbonization accelerated by wind which has important significance and use value is considered. Concrete carbonization of bridge structure accelerated by wind which is more reasonable than traditional method is considered. The design method can avoid the shortage of durability unequal on beam sections in theory, and extend using time of bridge structure.
