This paper firstly gives an overview of the development state of current method for evaluating bridge structural capability, and then discusses the internal differences and ties between the evaluation of static load test method and dynamic test evaluation method. Subsequently,a compositive evaluating index for bridge structural capability is established in theory, based on the contacts of the foregoing two kinds of capability evaluating methods. Finally, with the hope of providing a reference for relevant studies, the application of the compositive evaluating index is stated in detail.
Keywords: structural capability; static load test method; dynamic test method; compositive evaluating index
