RESEARCH ON THE SAFETY PERFORMANCE OF BRIDGE STRUCTURE UNDER THE EFFECT OF DISASTER LOAD
In order to explore the safety risks of the bridge under the action of disaster loads,by establishing a structured finite element analysis model,the structural behavior changes of the bridge under the action of disaster loads,and the wind stability assessment of the bridge passes the tremor of the lord's beam.Critical wind speed is completed.According to the disconnection of the main beams and main tower provided,the power stability of the bridge is used under the effect of calculating loads to avoid the structure of divergent vibration under the action of disaster loads and destruction.The results of the three-dimensional model simulation can be seen that the results meet the corresponding standards of displacement control requirements.It is believed that the overall risk is controllable.
