| dc.description.abstract | In this study, a numerical analysis method named Vector Form Intrinsic Finite Element(VFIFE) is used. Considering very small time increments and very small displacement increments, the stiffness matrix is introduced to calculate member forces in VFIFE. By changing stiffness matrix, calculating member forces with plastic hinges formed in the end of membersis demonstrated.
Since adopting a limited length element to simulate rigid zone in VFIFE will lead to numerical divergence, this study proposes an analysis procedure with plane frame element to consider the rigid zone. Three plane frame cases is chosen to discuss the difference between considering rigid zone or not. Simultaneously, this study propose plane frame combining with axial spring element to discuss the influence of element considering rigid zone and comparing with the case without rigid zone by two space frame cases respectively.
In addition, this study also proposes an analysis procedure with plane frame element to consider the rigid diaphragm in VFIFE, and discussing the influence of element considering rigid diaphragm that comparing with the case without rigid diaphragm. On the other hand, Review the influence of plane frame about the rigid diaphragm center’s degree of freedom by one degree of freedom, two degree of freedom, or three degree of freedom in three plane frame cases respectively.
