Seismic Design Decision Analysis. Inelastic Design of Building Frames to Resist Earthquakes
This study involves the development of a design procedure which allows control of the inelastic response of a building. The story ductility ratios and interstory displacements are used as a measure of this control, as these parameters seem directly related to possible collapse and overall damage in the building as the result of a severe earthquake. The building is reduced to a simple spring-mass model. Various design procedures involving Newmark's inelastic response spectra are used to design the stiffness and resistances of the springs. A dynamic analysis of the design models subjected to artificial earthquake motions is made to determine the effectiveness of the design procedures. Newmark's inelastic spectra are also evaluated. A design procedure is developed which gives control over the average values of interstory displacement and ductility ratio, but the desired uniformity of these parameters is not achieved. It is also concluded that to limit maximum values of parameters inelastic spectra should be made more conservative.
