短柱改进措施在高层建筑抗震设计中的应用
|
摘要
轴压比和剪跨比是影响构件延性的两个最主要因素,也是一对互成矛盾的因素。分析了高层和超高层建筑设计中如何正确利用剪跨比判定"短柱"问题的方法,并提出了改善"短柱"问题的具体措施。
The axial compression ratio and shear span ratio, which are two factors influencing the ductility of the component, are a pair of contradictory elements. This paper analyzes how to determine the problem of short column by using correctly the shear span ratio in the design of high- rise building and ultra-high-rise building, and puts forward some concrete measures for improving the short column.
