Elementary matrix of straight and curved beams, rod under axial force, and torsion were developed using spectral finite element approach. This method can be used to analyze the stmctural dynamic behavior. From the perspective of earthquake engineering, SEM allows to design structures subject to seismic excitation. The approach has advantages such as low computational cost, acctrracy in frequency/time response, and simple modeling of complex structures. The equations of motion, spectral relation, and the spectral elementary matrix were derived. The simple elements were combined into a 3D frame element and a global matrix was assembled. Time and frequency responses of 3D and 2D frame structures under a...
