碩士 === 國立交通大學 === 土木工程系所 === 94 === At present with the static analytic method, mostly one only considers the first mode effect. The high mode effect is also important for the unsymmetrical structures. Regarding the structural nonlinear analysis method, this thesis employs the 2D program and the 3D program. Also, the programs are used to do the Modal Pushover Analysis with consideration of high mode effect. The high mode contribution to the structural displacements is considered and the results are compared with that of dynamic nonlinear analysis of structures. Also, this thesis will employ stiffness distribution idea, to use 2D program to simulate torsion mode of the structure the torsion mode effect will be discussed.
