Inelastic Behavior of Steel Beam-to-Column Subassemblages,

摘要

A thorough experimental investigation of a column with two beams framing into it,was carried out. The selection of a model suitable for laboratory testing is discussed,and a description of the experimental setup and the testing procedure is presented. The experimental data obtained include the section properties,loading histories,comprehensive tables of all load and deformation parameters,load-deformation Hysteresis diagrams,deformation fields and strain (stress) distributions in the connection areas. A detailed interpretation of the test results is presented,including an evaluation of the significance of the most important geometrical and loading parameters with respect to strength,stiffness and ductility. The effect of these parameters on the energy absorption capacity and energy dissipation is studied. (Author)
