Abstract

For rapid evaluation of composite girder beam bridges load-bearing capacity, to study the load-bearing capacity check computation method based on displacement influence line. First obtain measured displacement data of typical sections by the slow driving way, then calculate the measured generalized displacement influence line by using Polynomial fitting method.Based on the generalized displacement influence line for virtual load test, and then complete the rapid assessment of bridge carrying capacity.The results of engineering application on one 30m simply supported T beam bridge show that:Compared with the load test method, this method results are reliable and convenient ,and can be used for rapid assessment of load-bearing capacity of composite girder bridges.
