Seismic strengthening of masonry infilled r/c frames with steel fiber reinforcement
Sevil, Tuğçe; Canbay, Erdem; Department of Civil Engineering (2010)
Seismic resistance of many buildings in Turkey is insufficient. Strengthening using R/C infills requires huge construction work. Feasible, easy strengthening techniques are being studied in Structural Mechanics Laboratory of METU. In this project, it was aimed to develop an economical strengthening method. This method is based on addition of steel fibers and/or PP fibers in mortar and application of mortar on masonry wall. Project was sponsored by the Scientific and Technical Research Council of Turkey (TÜB...
Seismic Retrofit of Deficient RC Structures with Internal Steel Frames
ÖZÇELİK, RAMAZAN; Akpinar, Ugur; Binici, Barış (2011-12-01)
This paper describes an experimental study on internal steel frames (ISFs) to retrofit seismically deficient reinforced concrete (RC) frames. One reference and six strengthened frame specimens were tested under constant gravity load and cyclic lateral displacement excursions. Installation of the ISF with and without anchors to the RC frame was examined. Test results showed that the snug tight ISF installed inside an RC frame may suffice to realize the benefit of implementing ISFs. If the horizontal shear st...

Masonry buildings have been, and remain, a popular form for economically enclosing space. Whereas such buildings are safe under gravity loads, most are vulnerable to horizontal loads due to earthquakes. Observations following an earthquake and experimental programs have shown that piers between openings are the most vulnerable part of a masonry building, and that the failure of such piers is due in the majority of cases to shear (or diagonal tension). Accordingly, the study described concerns the seismic...
Seismic retrofit of non-ductile reinforced concrete frames with chevron braces
ÖZÇELİK, RAMAZAN; Binici, Barış; Akpinar, Ugur (2013-07-01)
The use of chevron braces for seismic strengthening of existing non-ductile reinforced concrete frames was investigated experimentally and numerically. Five strengthened and two as-built reference portal frame specimens were tested under a constant gravity load and increasing cyclic lateral displacement excursions. The test results indicated that steel brace retrofitting increased the lateral stiffness, strength and energy dissipation capacity significantly. Specimens strengthened with square hollow section...
Seismic performance of gravity-load designed concrete frames infilled with low-strength masonry
Siddiqui, Umair A.; Sucuoğlu, Haluk; Yakut, Ahmet (2015-01-01)
This study compares the seismic performances of two reinforced concrete frame specimens tested by the pseudo-dynamic procedure. The pair of 3-storey, 3-bay frames specimens are constructed with typical characteristics of older construction which is lacking seismic design. One of the specimens is a bare frame while the other is infilled with low-strength autoclave aerated concrete (AAC) block masonry. The focus of this study is to investigate the influence of low strength masonry infill walls on the seismic ...
