Abstract

Abstract

The construction of T-type CR joints with stiffening plate is proposed, according to principle of box column inner diaphragm.It is revealed that a reasonable construction measure will make the stiffened joints show plastic failure within diaphragm plate first, and then within square chords, the ultimate strength of the stiffened joints improve distinctively, and show good ductility, through the static test of T-type joints.The effects of the construction measures, failure mode and ultimate strength of T-type joints with single plate and double plates are discussed, based on nonlinear finite element method.The study found that the intersection line may sag uneven, or the circular brace may appear local buckling failure because of inner diaphragm.The construction measure of stiffened plate and the scope of the joints ultimate bearing capacity are proposed, and the improper plate's size is avoided.
- RHS-CHS joints,
- inner diaphragm,
- failure mode,
- ultimate bearing capacity
