TRIANGULATION OF A LATTICE GIRDER, IN PARTICULAR OF A JIB ELEMENT FOR A TOWER CRANE

摘要

at the side of Sang - hyun (upper chord) and lattice girders, which are defined by the hahyeon (lattice girder) of the triangular structure is connected to the base point of the compression bars and hahyeon , a short length inclined connecting top of a compression bar to hahyeon tensile bars , and a compression bar adjacent the top of the compression bars is disposed substantially perpendicular to these prefecture the length of the connection comprises a long inclined tensile bars . In particular, this triangle connecting structure is used in the jib and counter jib elements of a tower crane .
