碩士 === 國立臺北科技大學 === 土木與防災研究所 === 100 === In this study, the main purpose of this study is to add new four functions into the Platform for Numerical Simulation - Point Based Computing (PNS-PBC) framework in National Center for Research on Earthquake Engineering (NCREE). These four functions include the five and nine point rigid elements, the geometry shape solver, the contact force models and the nonlinear hysteresis models. In addition, the PNS-PBC developer, user and vector manuals are written. The geometry shape solver includes the area, volume and moment of inertia. The contact force model is superimposed from the stiffness and damping forces. The contact force for the concrete block can be used to consider the different contact detections such as the line to line and line to surface et al. According to the numerical results, the new functions in PNS-PBC are the accuracy and effective.
