Abstract
FRP composite materials,because of its corrosion resistance and other advantages,are widely used.By using glass fiber reinforced plastic inner cylinder and steel outer cylinder together,a new type of composite chimney structure was formed.However,the analysis of the FRP composite chimney structure is rare.And,our country has no corresponding specification,so its design and calculation is more difficult.In this paper,we can only refer to the design and calculation method of chimney structure such as concrete chimney or steel chimney.ANSYS finite element analysis software is applied to analyze the dynamic characteristics and seismic response of steel tube-FRP inner tube composite chimney structure under seismic action by mode decomposition response spectrum method.Strength analyses are proceeded according to Tsai-Wu failure criteria based on the laminated shell theory of composite materials.And,the results are compared with those of steel chimney of the same structure size under earthquake action.Its advantages and feasibility of the new chimney structure are discussed,which provides reliable references for the aseismic design of the new composite chimney structure.关键词
