| Abstract: | Through the static bearing capacity laboratory tests of a 20-years in-service prestressed concrete hollow-plate beam unit, the deflections and concrete strain of each section under different load condition of this beam unit are studied, which can access to the static bearing capacity status of the beam element. Meanwhile, the finite element model of prestressed con- crete slabs unit is established by the finite element analysis software ANSYS. Then, the deflections and concrete strain of each section under different load condition are analyzed. The structural durability assessment and evaluation of overall performance can be evaluated through the comparing and analysis of experimental analysis results and the theoretical calculation results. |
