Abstract
More reliable assessment procedures of existing RC buildings are currently available, and have been introduced in the Italian and European codes reporting new rules for seismic design and analysis. However, further studies are necessary in order to upgrade such procedures and, specifically, to test the effectiveness of the capacity evaluation methods relevant to beam-column joints. To this purpose, a literature review on the subject and a wide experimental program on exterior beam-column joint specimens were carried out in the framework of the DPC-ReLUIS Project (Research Line 2, Task NODI). Some results are reported in the present paper to highlighting the role of the key behavioural parameters of RC beam-column joints, thus giving useful suggestions on the reliability of current code expressions and on possible improvements.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
