Abstract |
this paper describes the results of structural survey and analysis of wooden truss in building which is constructed nearly 100 years ago. Unlike experimental research, the initial condition that is el...astic stiffness, state of joint cannot be confirmed in the survey targeting actual framework. We tried to evaluate the stiffness of the frame by identifying eigenvalues and vibration mode based on the results of microtremor measurements. After that, we calculated the deflection of beam in the truss from the evaluated stiffness and structure of the frame, and considered about the difference from actual deformation.show more
