Sensitivity analysis of frequency and mode to the story stiffness of a shear structure

CHEN Wenyuan1,2,ZHAO Lei1,DU Bin1(1.School of Civil Eng.,Southwest Jiaotong University,Chengdu 610031,China;2.Sichuan Architecture Professional Technology College,Deyang 618000,China)  
Sensitivity analysis of the modal parameter like frequency and mode to the story stiffness of a frame structure is inconsistent,the first sensitivity analysis of frequency and mode to the story stiffness of a frame structure has been inferred.Numerical example shows that the first sensitivity of frequency to the story stiffness of a frame structure is higher than mode.
