摘要
基于有粘结预应力加固简支梁动力特性试验,提出了动力刚度加固概念,并根据试验结果推导了加固梁固有频率计算公式。利用大型有限元分析软件ANSYS进行了验证分析,结果表明计算公式具有较好的工程实用性,可为有粘结预应力加固设计提供一定参考。
Based on experiment of bonded prestressed reinforced simply supported beam, the concept of dynamic stiffness reinforcement is discussed, and according to the test results of reinforced beam, the inherent frequency calculation formula is deduced. The results are verified on using large - scale finite element analysis software AN- SYS. It is show that the calculation formula has better practicability, it can provide certain reference for bonded prestressed reinforced design.
