Abstract

Abstract

According to the tracking and monitoring of all course loading of specimens under 5 conditions,it is analysed distortion characteristic of integral frame and local vertical bars.The results show that the support have obvious lateral displacement of double direction,the distortion curve of the vertical bar is mainly b kind that is controled by nodal displacement,so the coupler steel tube falsework should be a frame with lateral displacement and semi-rigid node.In addition,a bridging has a good restriction on torsion and distortion of the falsework special attention should be given to its disposal in constructing.Distortion characteristic of the falsework bears important referrence value on founding theory of analyzing frame stability.
- coupler steel tube false,
- work distortion characteristic,
- test
