Elastic Plastic Analysis Of Seismic Performances Of The Special Shaped Reinforced Concrete Column Frame Structure

The special-shaped column frame structure is a new type of structure developed from the traditional rectangle section frame structure,The special-shaped column frame structure adopted T Shaped,L Shaped and Cross section of column replaces to the traditional rectangle section column Now there are moe studying the element of special-shaped column, but lacking study of the aseismic performances of the special-shaped column frame structure more deeply。The research of the aseismic performances of the special-shaped column frame structure is not only significant from theoretical aspect,but also important in practice。 The paper study the modal analysis,response spectrum,dynamic loading characteristics of the special-shaped column frame structure, The author analyze the number of floor ,the weight of floor,the stiffness of the column influence to the frequency of the frame structure;When the angle of horizontal seismic acts to the frame structure with the whole coordinate is 0,45,90 degree, we get the deformation and earthquake force,the average equivalent plastic strain,equivalent stress ,crack development and so on;At the same time,we study the damping influence to the special-shaped column frame structure;Finally ,we analyze dynamic loading characteristics of the frame structure applied the TAT software,we get some design suggestion by analysis :① the higher the structure,the bigger the frequency,What's more ,the frequency of the special-shaped column frame structure is bigger than that of the traditional frame structure;② The twisting stirrup should applied to the the whole corner column ,and the reinforcement ratio in corner column is bigger than that of other columns,what's more ,Structural measures shoud applied to the joint core of frame structure;③ To reduce development of the crack The less diameter reinforceing bar should applied to the column when designing;④ we should study the structural dynamic character in earthquake resistant design of structure。 The method of the paper is reliable,The conclusion and design recommendation are useful to the theoretical research and project practice。...
