An Innovative Design Strategy for Seismic Retrofitting of a High-Rise Steel Building in Kaoshiung

Abstract eng:
After the devastation and damage caused by the Chi-Chi Earthquake in 1991, Taiwan initiated progressive seismic building code provisions to strengthen design requirements for building design and construction. In response to the enhanced seismic design requirements, this case study elaborates on some innovative approaches to meet the stringent building code provisions, while addressing some unique experiments and analytical results applied for the retrofit of the once abandoned high-rise steel buildings located in Kaoshiung. The incomplete high-rise steel building in question was abandoned for various reasons. The main structural members were exposed to harsh weather and some had suffered from erosion. In order to meet the newly adopted seismic code requirements, it becomes a challenging task to complete this construction when building occupancy use also changes. A newly proposed beam-column connection was tested in order to prove its intended strength. Addition of buckling retrained braces provided damping to enhance this building’s seismic performance. The structural system was consequently changed to an eccentrically braced frame system to meet the stringent building draft requirement. Due to the obvious complexity of the structural performance as a result of these additions and revisions, a nonlinear structural analytical study was conducted to investigate the global behavior of the newly revised building. This case study aims to illustrate how innovative design strategies and construction techniques lead to a successful building retrofit project.
