Abstract

Research on infilled reinforced concrete frames is fundamental for the vulnerability assessment of existing buildings. The analysis of the interaction between infill and frame is an open issue in performance-based earthquake engineering due to its importance in predicting the dynamic behavior and failure modes of buildings. This study provides an open access database of laboratory tests on masonry infilled reinforced concrete frames, collected from the literature and harmonized in a consistent framework. The database is named Masonry Infill Database 1.1 (MID 1.1). The data were grouped in categories to calibrate a piecewise linear curve representing the lateral response of the infill depending on the masonry wall and the frame details. The gathered data were used to assess analytical models and numerical studies from the literature with the aim of revising the formulations currently used in the equivalent strut approach. An empirical model for the equivalent strut was developed through a power-law multiple regression of the database. The open access database in its spreadsheet form is intended to provide a useful tool for the analysis of infilled reinforced concrete frames.
