Since it is generally difficult to predict the occurrence of natural disasters such as earthquakes, a performance management system that always maintains the safety and functionalities of structures is required, especially for critical ones like nuclear power plants. In order to realize such a system, it is becoming important to carry out modeling procedures and analyses in detail to better understand the real phenomena. Such details are important in understanding the phenomena occurring in frame structures such as piping systems which are considered to be one of the vulnerable parts in nuclear power plants. The aim of our research is to solve the dynamic behavior of piping systems in nuclear power plants which are complicated assemblages of parts. The spectral element method is adopted in this work and the formulation considering a shear deformation of a frame element is described. The Timoshenko beam theory is introduced for the purpose of this formulation. The validity of the presented element will be shown through comparisons made with the conventional beam.
