对保定垃圾焚烧发电工程主厂房结构采用时程分析法进行地震反应分析研究,并对动力特性、位移、加速度等计算结果进行分析。厂房由于设有垃圾储存池造成结构刚度在平面、立面都不均匀,且纵向较横向严重,会产生较大的扭转,不利于抗震。垃圾焚烧工程主厂房结构的抗震设计应合理选择结构布置方案,采用多个空间有限元分析程序,合理选择参数进行分析。通过控制振型、结构位移等计算结果来控制结构的扭转,并适当提高抗震措施。
The seismic response analysis and research of the main plant structure of Baoding waste incineration power plant is carried out by using the time history analysis method, and the calculation results of dynamic characteristics, displacement and acceleration are analyzed. As a result of the garbage storage tank, the stiffness of the structure in the plane and elevation are not uniform, and the longitudinal direction is more serious than the horizontal direction, resulting in greater torsion, which is unfavorable to earthquake resistance. The aseismic design of the main plant structure of MSW incineration project should be based on a reasonable choice of structural layout scheme and adopt a number of spatial finite element analysis programs to reasonably choose the parameters for analysis. By controlling the vibration mode, the structure displacement and other calculation results to control the structure of the torsion, and appropriate to improve the seismic measures.
