Lateral in-plane seismic response of confined masonry walls: From numerical to backbone models
Confined masonry (CM) is a widely used solution for buildings in developing countries and has potential for worldwide application when considering its economic and constructive advantages. Although a large background of experimental testing of CM walls is available, numerical studies are further needed to extend the existing knowledge and derive analytical rules to adopt in design codes. In this work, a parametric numerical study is performed, aimed to characterize the lateral in-plane response of CM walls under different variables and to establish a dataset for comparison of engineering demand parameters, towards the proposal of predictive models. Benchmark walls tested under lateral in-plane loading are used to calibrate a finite element modelling approach for pushover analysis. Based on the results of the parametric study, a formulation and charts are proposed to respectively estimate the lateral resistance and displacement capacity of CM walls with features similar to the ones used as benchmark. ; The FEM analysis work presented here was developed in the scope of European Commission Mandate 'M/515 phase 1 tasks for the development of the 2nd generation of EN Eurocodes' coordinated by the Netherlands Standardization Institute (NEN), task SC6.T1 'Masonry Revised version of EN 1996-1-1'. The prolific discussions and suggestions of participants in the work of PT1 for SC6.T1 are gratefully acknowledged. This work was partly financed by FEDER funds through the Competitivity Factors Operational Programme - COMPETE and by national funds through FCT - Portuguese Foundation for Science and Technology, within ISISE (project UID/ECI/04029/2013). The Postdoc Grant SFRH/BPD/94677/2013 provided to the first author is acknowledged in particular.
