Inelastic seismic response of turbine buildings

Inelastic design of turbine buildings to withstand a Safe Shutdown Earthquake is one of the most cost effective ways to assure that they will not collapse onto adjacent safety related Category I structures. Application of the Newmark-Hall inelastic response spectra technique to turbine building seismic design is examined analytically for various cases of design. Emphasis is placed on the qualification of the structure to sustain SSF loading at a nuclear power plant site wthout collapse. This investigation of the inelastic design and analysis of turbine buildings due to gravitaty and seismic loading used three common turbine building farming configurations. These structures were designed for various design ductilities using Newmark-Hall inelastic spectrum modification procedure with the NRC Regulatory guide 1.60 design response spectra as a base. (Auth.)
