✦ Synopsis

A comparison is made of the dynamic response of a typical nuclear power plant to a modest earthquake (Parkfield) and to the impact of a small military aircraft (MRCA) and a large civil aircraft (Boeing 707-320). Finite element and modal supcrposition techniques are used to obtain the time-history response and the corresponding floor response spectra. The effect of soil-structure interaction is examined by varying the soil stiffness and damping over a range defined by soil shear wave velocities of 500 to 2000 m/second. A limited study is also carried out to assess the effect of embedment and foundation raft geometry on the seismic response of the structure.
