Steel buildings constructed in Hokkaido were surveyed in order to understand the current state of design and construction. Data on geometric, material, and structural features of 120 buildings, whose design was approved between 2010 and 2022, was extracted from design drawings. The buildings could be categorized based on the columns used: square-HSSs or Isections. The former adopted two-way moment-resisting frames. The latter tended to use braces in one of the two framing directions. The adopted design methodology, vertical loads, design lateral strength, and fundamental vibration frequency are analyzed. Trends in dimensions, steel grade, and arrangements of structural members are discussed.
