设有Maxwell阻尼器的连续梁桥的减震效果分析
|
摘要
用Fortran语言编制可以包含Maxwell阻尼单元的结构动力分析程序,研究阻尼器对连续梁桥的减震效果.研究表明:阻尼器可以减小结构的地震反应,使墩底的内力分配均匀,有利于结构的抗震设计;当合理地选择阻尼器的参数值时,Maxwell模型阻尼器对连续桥梁结构具有良好的减震效果.
Computer program for dynamic analysis of a structure including a Maxwell damping unit in itself as well was developed with Fortran and the damping effect of the damper on the anti-seismic performance of continuous girder bridges was investigated.It was shown by the investigation that the seismic response of the constructure could be decreased by using the damper,so that the distribution of inner force in the bottom of bridge pier was made uniform,benefiting the anti-seismic design of the structure.When the parameters of the damper was selected reasonably,a good damping effect of the structure of continuous girder bridge could be obtained with the help of Maxwell model damper.
