摘　　要：本工程在原有GGH支架结构的基础上新增烟道旁路,为避免新增钢烟囱发生横风向共振,采取措施增强了原有结构的抗侧刚度,同时减小烟囱支架的梁柱截面,并通过构造转换桁架实现了力的合理传递,较好地解决了工艺方案对结构造成的困难。A new flue bypass was added on the basis of the original GGH frame structure for a project,to avoid the across-wind resonance vibration of the steel chimney,measures were taken to enhance the lateral stiffness of the original structure,while reducing the sections of the beam and column for the chimney bracket,which created a transfer truss to achieve a reasonable transfer of the force,thereby the difficulties caused by the process scheme were solved.

关 键 词：烟道改造 钢烟囱 横风向共振 转换桁架
