| Abstract: | Through the dynamic and static loading tests of the five questioned beams from the two bridges,which are mainly composed of prestressed concrete simple T girders,and the theoretical analysis of the coving(or deflection) phenomenon of the questioned beams,this paper studies the reasons for the coving(or deflection) phenomenon of the questioned beams in the demonstration line.This paper provides a whole process of analysis for the coving(or deflection) phenomenon of such girder-bridges,so it's valuable for reference both in practice and in theory. |
