Free Body Analysis of Concrete-Encased Steel Column Base
-
摘要: 介绍了外包混凝土式钢柱脚的解剖分析,以揭示外包层是钢柱的支座还是与钢柱共同工作的一部分。在布置足够栓钉的情况下,给出了保证最低限度共同工作的外包高度,同时给出了栓钉数量计算公式。Abstract: Free body analysis of concrete-encased steel column base was carried out to reveal whether the exterior reinforced concrete wall was the support or a part of the steel-reinforced column(SRC). In case of enough studs, the minimum encasing height was proposed. Equations to determine the stud number were presented.
