Reliability of Simplified Modeling Strategies for In-Plane Walls in Urm Buildings Using Asce 41-13 Procedures
Abstract eng: The current ASCE 41-13 standard does not provide recommendations or include references regarding computational modeling strategies for performance-based seismic assessment of in-plane walls in unreinforced masonry buildings. This paper is attempting to fill this research gap through an evaluation of the reliability of three suitable simplified nonlinear modeling approaches for in-plane walls and providing a comprehensive list of references on more complex modeling strategies for masonry buildings. The models -namely nonlinear spring macro-models, equivalent frames and a layered shells- were validated under general monotonic, cyclic quasi-static and earthquake loading on two full-scale wall tests reported in the literature. To demonstrate their practical use, the models were developed in the commercial software SAP2000. The numerical simulations showed that the pushover capacity curve and hysteretic loops for base shear vs. roof displacements were generally in acceptable correlation with the experimental results.
