【摘要】 窑尾预热器塔架结构是水泥厂新型干法生产线中的重要工业建筑。通过采用动力弹塑性时程分析方法,分析研究某实际塔架结构不同强度地震动输入下的非线性响应及其规律,揭示结构在强震作用下的屈服机制及破坏模式,探讨斜撑构件在窑尾预热器塔架结构抗震性能中的作用,得出一些对预热器塔架结构抗震设计的有益结论。更多还原

【Abstract】 The frame structure of pre-heater is one important industrial building in the NSP cement production lines.It was investigated that the nonlinear responses of one certain pre-heater frame structure under variable earthquake intensity motions with elasto-plastic time-history analysis and also studied the inherent law.The analysis revealed the yield mechanism and the failure mode of the structure.It was also discussed the importance of brace member for the structure,and obtained some valuable conclusions for the aseismic design of pre-heater frame structure.更多还原
