Seismic response of short columns affected by brick/tile aggregate concrete wall infills

Various post-earthquake reports indicate that short columns are vulnerable structural members and significant source of serious earthquake damage. Observation that non-structural partial brick infills, comparatively to partial concrete infills, have less harmful effects on short columns put a new perspective on the use of recycled brick/tile as concrete aggregate with the additionally benefit of providing a sustainable management of such material. This paper discusses a numerical study on the influence of brick / tile aggregate concrete infills on the response of short concrete columns. In addition, this paper presents an approach for the analysis and design of short columns, similar to that of tie beams. Linear elastic analysis was carried out on four- and seven-story three-bay concrete frames using modal response spectrum analysis. Mechanical properties of brick and tile aggregate concretes determined by laboratory testing at Faculty of Civil Engineering Osijek are described and used in this study.
