Kajima Corporation (鹿島建設)

Kajima offers performance-based fire design, covering fire-resistance verification (耐火性能検証) and evacuation safety verification (避難安全性能検証, including the 2020 smoke-height method). It uses PSTARS, its own simulator that couples fire and smoke spread with occupant evacuation. It runs multi-purpose and wall-only fire-resistance furnaces that heat to 1,400°C under load. It also developed FR Wood (FRウッド), a fire-resistant glued-laminated timber.
