Abstract:
Since the assumed model of constraint is decisive for predicting longitudinal structural movements, for better predicting movements, some new models of constraints were introduced. The proposed models take into account the dynamic character of frictional forces in sliding bearing with PTFE elements. The applied models analysed by simulation program show notable consequences for both the designing and control of bearings. The presented problem of Structural Movement may concern the installation projects of joints and bearings for new bridges as well as routine control of existing bridges.
