Design Proposal of Confined Masonry Buildings

The design procedure included in the Peru new Masonry Design Code called “Norma E.070” for confined masonry buildings is presented. This procedure is based on experimental tests performed in Peru and other countries, theoretical studies, and the performance of actual masonry buildings during past earthquakes. In this design procedure, two seismic design levels are considered. For moderate earthquakes the structure is designed to behave in the elastic range, while for severe earthquakes, the structure behaves nonlinearly and provisions are given to limit lateral drifts and prevent strength degradation, so the structure can be economically repaired.
