PROBABILISTIC APPROACH FOR STRUCTURAL PERFORMANCE EVALUATION OF PORT RC STRUCTURE

Abstract

 The total of 40 RC slabs extracted fr om existing port structures was tested in order to evaluate the relationship between visually judged deterioration grades and load carrying capacities. Wide variations were observed in the relati onship in each deterioration gr ade, however, the load carry ing capacity tended to be smaller than the design expectations when the symptom of deterioration appeared on the surface of concrete members. Moreover, the relationship was greatly influenced by localized deterioration and its position in the member.
 Based on the statistical analysis on the relationship between deterioration grades and load carrying capacities, the probabilistic evaluati on methods of the load carrying capacities of RC slabs and whole RC members in an open-type wharf were proposed as qu antitative evaluation methods of residual structural performance of existing port RC structures.
