The objectives of this project were to study CSMIP records obtained during the October 17, 1989
Loma Prieta earthquake at a 49-story steel structure and to conduct an investigation of current
structural engineering design procedures related to the response. The recorded data indicated
that the top 6 stories of the building have experienced much greater drift than lower floors
due to discontinuity of mass and stiffness. The results of elastic and inelastic dynamic
analyses compared to CSMIP records confirmed validity of many design assumption currently used
while resulting in better understanding of actual behavior of these modern structures and
possible refinement of design procedures.
