The objective of this study is to assess the seismic performance comparisons of steel structures with different structural systems and ductility. The structural systems used in the study are divided into three categories: 1 moment resisting frames, 2 concentric braced frames, and 3 eccentric braced frames. In each structural system, the frames consist of 3 ductility, namely, 1. ordinary, 2 intermediate, and 3 special ductility. The levels of seismic density are considered at moderate density at Mueang Chiang Mai. The 8-story steel buildings locate in Mueang Chiang Mai, Thailand are considered.
