碩士 === 中原大學 === 土木工程研究所 === 100 === Abstract The main purpose of this study is to add some functions for different types of the elements into the Platform for Numerical Simulation - Point Based Computing ( PNS-PBC ) framework. This framework is developed from the National Center for Research on Earthquake Engineering (NCREE) in 2011. The PNS-PBC is based on two methods which are vector form intrinsic finite element (VFIFE or V-5) method and discrete element method (DEM). In this study, the formulations of the shell, cable, spring, 4 point solid, Euler beam, Timoshenko beam in VFIFE method are implemented in PNS-PBC. Firstly, the internal forces of the Timoshenko beam, cable, and spring for VFIFE method are derived in this study. In order to prove the accuracy for deformation of the elements, the rotation tests and numerical simulations using ANSYS are compared with the numerical simulations using VFIFE method. It is confirmed the good accuracy of the VFIFE method.
