Predicting the behaviour of HSS double chord trusses—a comparison with test results

Predictions from a previously developed analytical model that takes into account plastic hinging action and includes the effects of axial load and moment interaction are compared with the results of tests on double chord RHS trusses. The model incorporates a shear spring mechanism that is applicable to gap joints of HSS trusses. Load–displacement curves generated by the program are in reasonable agreement with the majority of truss tests. However, calculated moment – axial force interaction curves tend more to predict trends of behaviour rather than to be quantitatively accurate.
