碩士 === 中華技術學院 === 土木防災工程研究所 === 98 === The dynamic time history responses of the torpedo railway train have been performed an extensive analysis using SAP2000- a finite element package. The results of numerical simulation using SAP2000 compared with those conducting with SASSI2007.-a more rigorous finite element package. The objective in this research is to evaluate the feasibility of SAP2000 replacing the role playing by SASSI2007. The methodology of simulation of the wheel moving point loads implementing SAP2000 must appropriately model the sleepers and railings with the accurate velocity of the torpedo railway trains. The soil-structure interaction is simulated with Link Element in SAP2000. The point moving loads are replaced with triangular distributed loads to reduce the demanding of degree of freedom in modeling and enhance the calculation capacity.
