本文报道了2016年熊本地震对RC学校建筑的破坏，特别是二级平墙的严重剪切破坏。通过微震观测对建筑物的振动特性进行了评价。此外，通过数值模拟对建筑物的破坏进行了研究。一系列参数分析表明，二次平壁的数量会影响坍塌机理。当局部坍塌机制形成时，建筑物的极限变形能力降低，本文提出的评价方法能很好地评价建筑物的极限变形能力。
This paper reports damage to an RC school building, particularly severe shear failure to secondary flat walls, by the 2016 Kumamoto earthquake. The vibration characteristics of building were evaluated by micro-tremor observation. Additionally, the damage to the building was investigated through numerical simulations. A series of parametric analyses revealed that the amount of the secondary flat walls would affect the collapse mechanism. Ultimate deformability of the building decreased when a partial collapse mechanism was formed, which was well evaluated by an evaluation method proposed herein.
