| Abstract | ||
| The analysis of steel-concrete composite joints presents some particular aspects that increaserntheir complexity when compared to bare steel joints. In particular, the influence of slab reinforcement andrncolumn concrete encasement clearly change the moment-rotation response of the joint. Starting from anrnenergy approach developed in the context of steel joints, an extension to composite joints is presented inrnthis paper that is able to provide closed-form analytical solutions. In addition, the possibility of tri-linear orrnnon-linear component behaviour is also incorporated in the model, enabling adequate treatment of therninfluence of cracked concrete in tension and the softening response of the column web in compression.rnThis methodology is validated through comparison with experimental tests carried out at the University ofrnCoimbra. | ||
