- Abstract
- This report is concerned with determining the seismic response of a supporting structure for two handling elevators at a TVA steam power generating plant in Paradise, Kentucky. It describes the dynamic behavior of the system, modeling, frequencies and mode shapes, a 3-dimensional plotting program, a response spectrum analysis, an earthquake time-history response analysis, and discusses results based on two types of graphical presentation. The 3-dimensional plotting program has the capabilities of displaying either the basic structural model or of superimposing a deformed structural configuration, such as mode shape, upon the original undeformed configuration. Illustrations include descriptions of a general 3-dimensional beam finite element and a general quadrilateral plate finite element in a 3-dimensional space, a basic structural model, vibrational modes, yield and buckling ratios, Z-displacement time-histories, axial stress time-histories, and bending moment time-histories.
