我国大多数装配式多层厂房结构均采用预制长柱明牛腿框架型式,而节点大都为明牛腿刚性节点。这种节点的静力性能已被实践证明是好的,但其抗震性能在国外研究得很少,在国内也刚开始进行试验研究。我们于1980和1981年先后做了二批试件(共14个)的抗震性能试验,初步探索了这种节点在反复循环荷载作用下的受力性能,在地震荷载作用下这种刚性节点具有较大的承载能力, Most of the prefabricated multi-storey factory buildings in China adopt the prefabricated long-column calf-barrel frame type, and the nodes are mostly rigid bovine leg joints. The static performance of this kind of node has been proved to be good in practice, but its seismic performance is rarely studied abroad, and it has just begun a trial study in China. In 1980 and 1981, we conducted seismic performance tests for two batches of test pieces (14 in total), and preliminary explored the mechanical behavior of this joint under repeated cyclic loading. This rigid node has the effect of seismic loads. Larger carrying capacity,
