Abstract
A series of tests has been performed at I.T.U. Structural and Earthquake
Engineering Laboratory, to examine the differences between the structural
behaviour of infilled RC frames strengthened by CFRP fabric with different
connection details.
Five identical ½ scale, one storey-one bay brittle brick infilled reinforced
concrete frame specimens have been tested under cyclic lateral loads. The
reinforced concrete bare frame and plastered brittle brick infilled RC frame are
essentially reference specimens. Three other specimens have been strengthened
using CFRP fabric with different connection details.
The comparative results including lateral load capacities, failure modes and
energy dissipitation are presented in this paper.
Keywords: infill wall, strengthening, CFRP, masonry.
1 Introduction
Neglecting the effects of non-structural brittle infill walls on dynamic
characteristics of structures, such as stiffness and lateral strength, is a common
assumption during the design and sometimes during the assesment stages of
reinforced concrete structures subjected to lateral load. The field observations
made after the recent major earthquakes in Turkey and many researchs
performed throughout the world showed that this kind of approach leads to
mispredicting the real behaviour of reinforced concrete infilled structures under
lateral load. Research should be done to obtain a more relastic mathematical
model that takes the infilled frame behavior into account and a strengthening
method that includes infill wall properties for having cheaper rehabilitation
alternatives.
The experiental work that is presented in this paper is a part of four
complementary experimental works of research project launched in Structural
Keywords
infill wall, strengthening, CFRP, masonry.
