Historic buildings, mainly if not in use or even in ruins, are frequently subjected to structural instability that causes serious and irrecoverable losses of precious antique materials and sometimes causes risks for people nearby the building. There are also situations of post-earthquake damage that require interventions for structural safety, where efficacy, easy operability as well as cheapness are needed. The most usual safety systems make use of props or scaffoldings which, although providing versatility and good resistance, at the same time can be bulky and do not allow free access to the building. As an alternative to scaffolding, the use of steel stay cables can ensure an adequate level of safety and a reduction of lost space. As a further possible solution, in recent years, polyester straps offer excellent confinement possibility, incrementing resistance to traction, with the possibility of pre-tensioning the system by means of "ratchets", so that an immediate, active,intervention can be obtained. In the paper some cases related to the safety of historic buildings are shown, using solutions alternative to props.
