ABSTRACT
ABSTRACT: Until now composite joints are designed as pinned or as continuous joints. A continuous joint requires stiffeners in the column and high degrees of reinforcement, whereas a pinned joint requires some minimum reinforcement for crack width control that however is not considered to provide any moment capacity. Optimised solutions are partial-strength joints that consider the moment resistance and that allow easy and cheap producible joints with small degrees of reinforcement and without stiffeners in the column. Using partial strength joints, in the ULS in structural systems a moment redistribution occurs resulting in a certain rotation in the joint, the so-called required rotational capacity. It has to be taken care for that the available rotational capacity of the joint is sufficient in comparison to the required rotation. In this publication means are given in order to calculate the required and the available rotational capacity.
