Simulate the nonlinear material and nonlinear geometry behavior of pre-stressed concrete or reinforced concrete. VFIFE is a vector form analysis method that is different to traditional finite element method. Advantages of VFIFE are point describe, inverse rigid body motion in each path element and no need to solve the matrices. This thesis based on VFIFE frame element extend to composite material section frame element for calculate the pre-stressed concrete internal forces. For section strain distribution must be satisfy the assumption plane remain plane, pre-stressed concrete Internal forces program quotes Fiber Cross Section Method and iteration method to calculate the axial force and moment, and compare with software Response2000 which is developed by University of Toronto, verify internal force program by the Moment-Curvature diagram. Internal force program add in VFIFE method to do structure analysis. Finally, Results of this thesis provide some information of pre-stressed problem to Academic and Engineering. en_US DC.subject 向量式有限元 zh_TW DC.subject 向量式 zh_TW DC.subject 預力混凝土 zh_TW DC.subject 預力 zh_TW DC.subject 纖維斷面分析 zh_TW DC.subject Vector Form Intrinsic Finite Element en_US DC.subject VFIFE en_US DC.subject Pre-stressed Concrete en_US DC.subject Pre-stress en_US DC.subject Fiber Cross Section Method en_US DC.title 向量式預力混凝土二維剛架元之數值模擬與驗證 zh_TW dc.language.iso zh-TW zh-TW DC.title Numerical Simulation and Verification of the 2D Vector Form Pre-stressed Concrete Frame Element en_US DC.type 博碩士論文 zh_TW DC.type thesis en_US DC.publisher National Central University en_US
