“…At the local level, infill causes asymmetry and concentration of the frame deformation. Stavridis et al [14] conducted shaking table test of a three-story RC frame infilled with solid masonry walls in one bay and infill walls with window openings in the other bay and found that infill walls with openings are much more vulnerable to collapse than solid walls.…”

Abstract-Commercial and residential buildings are usually constructed of steel or reinforced concrete frames with unreinforced masonry infill panels. Many codes of practice ignore the stiffness during design process for ease of design. Many designer engineers also do not know how to incorporate this additional stiffness from the unreinforced masonry infill panels into the design process. This leads to an incorrect assessment of the building's robustness when subjected to lateral loading and especially when subjected to seismic ground motion. The natural frequencies, corresponding mode shapes and the strength of the building is therefore incorrectly assessed leading to an overdesign. When these buildings are modelled using Finite Element Analysis, it is imperative that the strength of the unreinforced masonry infill panels are correctly accounted for, to prevent over strengthening the columns to yield the same experimental test results. The paper therefore focuses on describing the possible failure modes caused by unreinforced masonry infill panels on reinforced concrete framed structures and the FE modelling techniques required to obtain a computationally efficient model. The investigation shows the significant effect of the unreinforced masonry infill panels on the robustness of the global model. Keywords-stiffness of unreinforced masonry panels, FE analysis, equivalent strut methodI.

“…These towers did not interact with the structure during the tests as they were placed with a 2-cm gap from the specimen. Further details on the design and configuration of the specimen and the shake table tests can be found in Stavridis (2009) and Stavridis et al (2012).…”

This paper presents a study on the identification of progressive damage, using an equivalent linear finite-element model updating strategy, in a masonry infilled RC frame that was tested on a shake table. A two-thirds-scale, 3-story, 2-bay, infilled RC frame was tested on the UCSD-NEES shake table to investigate the seismic performance of this type of construction. The shake table tests induced damage in the structure progressively through scaled historical earthquake records of increasing intensity. Between the earthquake tests and at various levels of damage, low-amplitude white-noise base excitations were applied to the infilled RC frame. In this study, the effective modal parameters of the damaged structure have been identified from the white-noise test data with the assumption that it responded in a quasi-linear manner. Modal identification has been performed using a deterministic-stochastic subspace identification method based on the measured input-output data. A sensitivity-based finite-element model updating strategy has been employed to detect, locate, and quantify damage (as a loss of effective local stiffness) based on the changes in the identified effective modal parameters. The results indicate that the method can reliably identify the location and severity of damage observed in the tests.
