As in-plane buckling bracing element transfers load to gusset plate, in length is smaller than out of plane buckling length then proposed detail the load path goes from bracing element proper selection and detailing design of bracing elements primarily to HP and then continues through gusset plate. section and its connection detail are determinant points to HP design features obey the same rules as gusset plate alter buckling mode to in-plane mode.
Additionally energy requirements; but its geometric dimensions are mostly dissipation through in-plane buckling mode is more dedicated for plastic hinge formation.
Specimen slenderness is 52 ( kL/r) which is similar practical to the method used in conventional steel to in-plane buckling mode of cross bracing in common workshops.
Development of yielded face hinges is simultaneous with the sudden in-plane buckling resulted in local buckling and formation of first plastic deflection at the load of 176 kN.
