摘要
民用住宅悬挑阳台事故多源于负弯矩钢筋下移导致的悬挑板倾覆,混凝土强度不足导致的悬挑板断塌,悬挑板厚度不足导致的受压区混凝土碎裂。通过对一例特殊因素导致的悬挑阳台事故进行调查,分析该工程悬挑阳台顶板发生塌落事故的原因,提出保证民用住宅悬挑阳台安全的建议。
Accidents related to the cantilevered balcony happened frequently in recent years,most of which could be attributed to the moving down of negative reinforcements,the low concrete strength of cantilevered plates,or the concrete crushing related to insufficient thickness of cantilevered plates.
