Method Of Influence Line Based On Measured Simply Supported T Beam Bridge Structure And Calculation Of Evaluation

The existing load bearing capacity evaluation method of bridges based on static load test is the most commonly used methed in China now,because it is more relible compared with other methed,but it also has some disadvantages such as time-consuming and laborious. So it is valuable to develop some rapid evaluation method of bridges which can overcome some disadvantages of the existing methods.For this purpose, a preliminary study on Load bearing capacity evaluation method of T beam bridge based on t field tested quasi-static generalized influence line was done.In this paper,the basic prinple of the above mentioned method was given.And a case study of a prestressed concrete simply supported T beam bridge was also given,which shows that the accuracy of the proposed methodis is acceptable.
