The Simulation and Prevention of Continuous Rigid Frame Bridge Disease

Being economical and applicable,continuous rigid frame bridge has found wide application in western China.However,with time,the mid-span deflection became a marked disease,and even influenced the common use of the bridge.A user creep program is compiled with ANSYS UPFs and FORTRAN77 for the simulation and analysis to this disease.Some preventive measure is put out to avoid the disease of mid-span deflection.
