Abstract: When the bar in RC frame rusted by the chloride ion, how to analysis the capacity of structure. According to different needs and different rusting performance, we can make the strategy and get the goal of structure strengthening. With a model in a salt factory, introduce the strengthening measures of rusted structure by the chloride ion. Now, this RC frame has been used 3 years after strengthening,it,s a successful case.
Keywords: RC frame;bar rust;strengthening decision;strengthening measures
