Experimental research on load-bearing capacity of frame columns with construction joint under low-cyclic reversed loading

摘要

In this paper, in order to study the load-bearing capacity of frame columns with construction joint under low-cyclic reversed loading, nine specimens were made, divided into three groups. Every group had three specimens, the first were made without construction joint, the second had fine processing construction joint, the third had simple processing construction joint. The three groups were loaded in axial compression ratio of 0.23, 0.34, 0.46 respectively. The results show that the influence of different processing with construction joint to crack position ultimate bearing capacity, skeleton curves.
