Study on Damage Prediction and Preparedness Effect of Furniture Overturning Based on Earthquake Damage Investigation

1.结构和室内损坏之间的关系虽然结构损坏往往是较新的建筑房屋较少，室内损坏发生几乎一致独立的房屋建筑年龄。为了减轻人为破坏，即使是新房子，也必须做好家具倾覆的防震准备。家具倾覆率的脆性曲线本函数与Okada和Kagami（1991）提出的关系式一致。采用问卷调查法确定的地震烈度作为强地震动指标。在JMA地震烈度6度时，家具倾覆率变化很快。3.宫城近海地震的人员伤害预测考虑到宫城近海地震情景下高层建筑的楼层反应，预测了家具倾覆造成的人员伤害。暴露于室内空间中的强地板响应等高危害的人数有所增加。随着建筑规范的修订，建筑物结构性损伤导致的人身伤害趋于减少，但在城市地区，人身伤害的可能性正在增加。从防震减灾的角度提出了考虑防震减灾的家具倾覆易损性曲线。讨论了根据楼层反应采取应急措施的效果。在有限的时间和预算下有效地减少灾害风险的战略是必要的。对提高抗震能力的影响作为风险沟通工具之一，对社区诊断表进行了研究。

1. Relationship between structural and indoor damageWhile structural damage tended to be less for houses of newer construction, Indoor damage occurred almost uniformly independent of the house construction age. For mitigation of human damage, earthquake preparedness against furniture overturning is necessary even for new houses.2. Fragility curve for furniture overturning ratioPresent function agree with the relationship presented by Okada and Kagami(1991). The seismic intensity evaluated by the questionnaire survey is used as a strong ground motion index. In the seismic intensity 6 of the JMA scale, the furniture overturning ratio changes rapidly.3. Human injury prediction against the Off Miyagi EarthquakeHuman injury by furniture overturning was predicted considering the floor response of high-rise building against the Off Miyagi Earthquake scenario. The number of people exposed to high hazard such as the strong floor response in an indoor apace has increased. While human injury due to structural damage to the building tends to decrease according to the revision of the building code, the potential for human injury is increasing in urban area.4. Disaster mitigation effect by earthquake preparedness strategyFragility curve for furniture overturning considering the earthquake preparedness was proposed. The effect of the preparedness action according to the floor response was discussed. The strategy to reduce a disaster risk effectively under the limited time and budget to next earthquake occurrence is necessary5. Influence for improving seismic resistance capacityA diagnosis sheet for neighborhood community was examined as one of risk communication tools.
