项目摘要

Flat-plate is one of the most widely used forms of construction among the low-to-medium-rise residential or office buildings. Recent earthquakes such as the Armenian (1988) and Mexican (1985) earthquakes have proven the susceptibility of such buildings to severe damage. In situations where an independent lateral load resisting system is not present or is rendered ineffective, the survival of such buildings in the event of an earthquake depends entirely on the performance of slab-to- column connections. The use of high strength concrete and fiber reinforced concrete in the connection region or the addition of shear caps can possibly improve the shear strength of slab-column connections without resorting to other relatively more expensive alternatives. Eight one-half scale two-bay flat- plate subassemblies will be tested under simulated earthquake- type loading to investigate the promise of such alternatives in improving the seismic resistance of flat-plate buildings. This study should provide the basis for improved safety of flat-plate buildings to include the use of high strength and fiber reinforced concrete and for further improvements in analytical modelling of the unbalanced moment transfer mechanism at the slab-column connections.
平板是中低层住宅或办公建筑中应用最广泛的建筑形式之一。 最近发生的亚美尼亚地震(1988 年)和墨西哥地震(1985 年)等地震已证明此类建筑物容易遭受严重损坏。 在不存在独立的横向荷载抵抗系统或变得无效的情况下,此类建筑物在地震中的生存完全取决于板与柱连接的性能。 在连接区域使用高强度混凝土和纤维增强混凝土或添加剪力帽可能会提高板柱连接的抗剪强度,而无需采用其他相对更昂贵的替代方案。 八个二分之一比例的两开间平板组件将在模拟地震型荷载下进行测试,以研究此类替代方案在提高平板建筑抗震性能方面的前景。 这项研究应该为提高平板建筑的安全性(包括使用高强度纤维混凝土)以及进一步改进板-柱连接处不平衡力矩传递机制的分析模型提供基础。
