接头中的压力可以通过接触来转移,相应地附加构件的缺陷对柱性能的影响必须考虑。如果柱的纵向放有一个接触片,其初始缺陷将对柱的屈曲性能产生影响,进而影响柱的承载能力。对构件性能、连接片设计及其紧固方式进行一系列研究,同时针对不同形状连接片进行足尺试验。将试验结果与极限承载力计算结果及各种设计方法进行比较。尤其对柱跨中直接叠放的接触片的稳定性能进行了研究,并且归纳出其屈曲曲线。
The pressure in the joint can be transferred by contact and accordingly the effect of the defect of the additional component on the column performance has to be taken into account. If there is a contact piece in the longitudinal direction of the column, its initial defect will affect the buckling performance of the column, thus affecting the carrying capacity of the column. A series of researches on the component performance, the design of the connecting piece and its fastening method were carried out. At the same time, the full-scale test was conducted on the connecting pieces of different shapes. The test results are compared with the results of the ultimate bearing capacity and various design methods. In particular, the stability of the contact pieces directly stacked in the column span was studied, and the buckling curves were summarized.
