Research and Example Verification on Stability Coefficient of Vertical Bar of Fastener Steel Pipe Support

The calculation method of steel pipe support in current specifications is not uniform, and it unsafe to directly apply the stability coefficient vertical bar code, which leads frequent safety accidents fastener supports. Through field statistics initial defects pipe, found that bending values 3 m 6 pipes with largest size are larger L/400. table obtained by taking L/400 as defect, 43.15% smaller than given specification. comparative analysis actual engineering monitoring results, results original specification after correction coefficient, concluded stress calculated proposed this paper similar project greater rod It suggested corrected should be applied project.
