中文摘要：

基于高层工业厂房煤气化结构具有双向偏心的属性和在地震作用下会发生扭转的特性,分析了地面转动加速度分量对结构扭转产生的影响;同时结合振型分解反应谱法对高层工业厂房煤气化结构进行抗震设计,讨论了结构双向偏心距变化对结构各层剪力、扭矩的影响。结合算例可知：结构偏心距的变化对结构的扭转产生较大影响,当偏心距增大1倍时,扭矩最大增长率为112.64%。

英文摘要：

In view of the properties of the coal gasification of high-rise industrial plant with biaxial eccentric structure and the characteristics of the torsion under seismic action,the influence of ground rotational acceleration component on structure torsion was analyzed.Meantime,combined with vibration mode decomposition response spectrum method,the seismic design of the coal gasification structure of high-rise industrial plant was conducted,and the influence of biaxial eccentricity changes on structure torsion was discussed.Combining with examples,it is known that the changes of the structural eccentricity have great influence on the structure torsion,when the eccentricity doubled,the maximum growth rate of torsion is close to 112.64%.
