Abstract

The joints of the assembled concrete frame structure are studied by the white light speckle method. Compared with the results of whole-body casting frame structures, the joints of the assembled frame have the weak stiffness. The conclusions provide a reasonable mechan-ical model of the assembled frame structure to the engineers. The in-plane rotations are expressed as the function of the displacement distribution in the paper. The white light speckle provides the local displacement distribution about the joints and the in-plane rotation can be obtained. Some photocarrier techniques are used to improve the accuracy of the white light speckle method. Besides, both the assembled and whole-body casting frame structures are are studied after the cracks appear. The variation of the mechanical model is discussed.
