Substructure method considering local buckling in steel frame advanced analysis
The stress, displacement, member size, local buckling and system buckling constraints of the structure are taken into account.
The concept of the buckling-strength coefficient to determine whether the local buckling occurs in the member is put forward.
This paper deals with the local buckling of beam-column with partial yielding of its section.
The experiment result showed most of the small slenderness members were controlled by local buckling, and the large ones were controlled by overall buckling.
Considering the membrane effect of plates, the design of profiled steel sheets allows local buckling of plates, and can utilize post - buckling strength.
The research of local buckling occurred in coped beam is still rare. Besides the coped size and other relative parameters have a large influence on buckling load of steel beam.
For the local buckling failure of brace tube in tubular K-joint experiment, the concept and principle of welding thermo-harm is presented.
Based on the simulating result of FEM numerical experiment, this paper investigates the effect of local buckling on the hysteretic behavior of tubular columns under cyclic unaxial load.
The local buckling of web plates in I-girders under wheel loading has been rarely investigated, due to the unknown distribution of bearing stresses in the web plates.
It is found that the critical local buckling stress and diameter to thickness ratio of circular steel tube are considerably increased by the support of filled concrete.
To determine precisely the bearing capacity of the Q460 single equal-angle steel strut, the local buckling caused by the overrun of width-thickness ratio should be correctly analyzed.
