hinge at mid-height of bracing element at the load of 165 For the purpose of increasing the reliability of kN. measurements buckling load of specimen is compared in Next to formation of mid-height plastic hinge, at the three different methods and revealed in Table 1.
First row load of 176 kN the HPs in both ends yield and cause the shows the recorded buckling load by actuator load cell.
Table 1: Buckling Load Method Buckling load (kN) Deviation (%) Actuator load cell 158 0 Strain gauge base 176 11 AISC (slenderness ratio = 52) 161 2
Additionally the the table, there is good agreement between the buckling weakness in most of the built up steel profiles in buckling load from test and code. through their weak axis is compensated.
at the buckling load.
