The Stiffness of the Tenon and Mortise Connection of Ancient Timber Buildings with the Random Incentive Action of Transportation

Abstract:

In this paper, on the basis of the dynamic response monitoring of the Xi’an Bell Tower, based on the random nature of traffic vibration, to use the vibration response data of ambient excitation directly, and obtained for monitoring the free decay of the Xi’an Bell Tower vibration signal response by using random decrement technique, then as this input, preparation of the corresponding computer program Matlab, has gotten the main dynamic parameters of the Bell Tower by using ITD method; in connection with the wooden beams of semi-rigid connection tenon characteristics, the upper wooden structure’s three dimensional finite element model, after Analysis of modal , fitting wooden the Bell Tower has been model tenon and mortise connection stiffness.
