Discussion of Processing Method for the Nondestructive Detection of Concrete Prestress Truss

摘要

The concrete prestress truss to detect has been built for 47 years, because of function transfo- rmation, the load increases, it's necessary to find out that how much load can the prestress truss bear. At the same time, the owner demands that the original structure can't be desructed during the detection. Based on this, we detect the prestress truss's bearing capacity by pasting Strain gages to control rods and detect stress, set crane hammer and batch to mesure the roof truss's deflection, then build model and make finite element analysis, so as to offer basis of reinforcement design to design organization.
