STAIR STRUCTURE CAPABLE OF DISSIPATING ENERGY

摘要

PURPOSE: A stair structure of energy dissipating type is provided to minimize noise and to reduce vibration while maintaining the steel stair structure of a dry construction method by dissipating vibration energy by load which is delivered from an upper plate. CONSTITUTION: A stair structure of energy dissipating type comprises an upper plate and a vibration preventing part(130). The upper plate is installed in the upper part of a stepping plate. The vibration preventing part is combined between the stepping plate and the upper plate and is vertically deformable. The vibration preventing part reduces the vibration of a steel stair and prevents noise when the load is delivered from the upper plate.
