Seismic Structural Response and Safety of a Large Fossil Fuel Steam Generating Plant

摘要

Seismic response studies using finite element models are summarized for two steam generators and their supporting structures of a 1,200 MW and a 600 MW fossil fuel steam generating plant. Prior to modeling, dynamic behavior analyses were performed on five major subsystems; supporting structure and steam generator; high pressure steam piping; stack; cooling tower; and coal handling equipment. The complexity of each subsystem required the use of large computer codes from the start. The NASTRAN modeling code which doesn't require excessive computer time was decided upon for general implementation. Principal findings and suggested areas for future research for each subsystem are presented. Also included are abstracts of theses and lists of publications and scientific collaborators.
