Masonry infills are frequently used as enclosure walls in Reinforced Concrete framed buildings. In the common design practice they are generally modeled as non-structural elements, neglecting their influence on the building seismic response. The current Italian seismic code consider non-structural elements in the definition of the life safety limit state, but safety verifications, in particular with respect to the out-of-plane direction of infill walls, appear to be critical since no capacity models are specifically provided. With the objective of providing suggestions to improve the current Italian seismic code, after a description of the infill walls typically used in Italy, in the present paper the capacity models available in the technical literature are described and compared among them. Besides providing some preliminary suggestions for design practice, this paper prepares the ground to a next work where the capability of the available models in estimating the out-of-plane capacity will be verified by comparing them with experimental results.

Abstract
Masonry infills are frequently used as enclosure walls in Reinforced Concrete framed buildings. In the common design practice they are generally modeled as non-structural elements, neglecting their influence on the building seismic response. The current Italian seismic code consider non-structural elements in the definition of the life safety limit state, but safety verifications, in particular with respect to the out-of-plane direction of infill walls, appear to be critical since no capacity models are specifically provided. With the objective of providing suggestions to improve the current Italian seismic code, after a description of the infill walls typically used in Italy, in the present paper the capacity models available in the technical literature are described and compared among them. Besides providing some preliminary suggestions for design practice, this paper prepares the ground to a next work where the capability of the available models in estimating the out-of-plane capacity will be verified by comparing them with experimental results.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
