The Dynamic Characteristic and Response's Discussion of External Prestressing Curved Beam
The main contents of dynamic characteristic and response of external prestressing curved beam are as follows: The research is about frequency characteristic of external prestressing curved beam. With analysis of variable regulation, the natural frequency's theoretical formula can derived from natural vibration frequency under structure concrete damage .Resonance prevention of external prestressing curved beam is vital. Through explicit beam frequency, external cable and external excitation, and the relationship between above each other can prevent resonance destruction .By analysis of dynamic performance's parameter sensitivity , external prestressing curved beam can be obtained sensitivity parameter of dynamic performance .Model test study of dynamic external prestressing curved beam is also critical. Based on research achievements of existing theory, dynamic model test can be carried on, which would obtain vibration regulation of verification and comparison with structure data.
