Abstract

Abstract

A series of studies were performed on pin-disk type steel tube support frame，including the reliability of pin-disk joint，the pullout force of pin，the horizontal and standing rod joint stiffness，the mechanical property of basic unit． The research results indicate that pin-disk joint is reliable to ensure the supporting frame’s safety． The designed wedge pin has self-locking function，and it will not slide automatically in the normal working state． The horizontal and standing rod connection is a semi-rigid joint，the joint stiffness coefficient was measured through experimental analysis． The supporting frame failure mode and ultimate bearing capacity were obtained through the mechanical property study on basic unit． The influence of brace layout，cantilever length on the top of the supporting frame and pole step on the mechanical properties of supporting frame was determined by contrast．
