According to the past researches, the structural damage of high-rise steel building when subjected to long-period ground motions is characterized by the concentration of deformation to beam-column connections. In addition, it is known the field weld connection details tend to have poor deformation capacity. So far, there is no comprehensive data base about beam-column connection details of existing high-rise buildings. This study provides a data base of high-rise steel buildings, focusing on the beam-column connection details.
