an experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. the first specimen was a reinforced concrete frame with solid-brick infill. the second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. the last specimen was a reinforced concrete frame without any infill. these three specimens were tested by pseudostatic method. di...

Original scientific paper Reinforced-concrete (R/C) frames infilled with masonry wall, especially with the presence of an opening, are insufficiently explored structural elements. We have experimentally investigated influence of the opening’s type and position to the lateral response of reinforced-concrete frames with masonry infill. Correction factors, that take into account influence of the o...

4 FRP strengthening systems for infill masonry walls are typically designed to resist flexural stresses due to out-of5 plane pressure. Previous research has shown that there are potential premature failure mechanisms due to shear 6 sliding of the infill, which could reduce the effectiveness of the strengthening system. Current design guidelines for 7 strengthening of masonry walls with fiber-re...

A thin layer of ductile fiber-reinforced mortar material referred to as Engineered Cementitious Composites, or ECC has been experimentally investigated as a seismic retrofit for unreinforced masonry infill walls in non-ductile reinforced concrete frames. Compression tests of masonry prisms retrofitted with 13mm of ECC were conducted representing the compression strut of a masonry infill under i...

Masonry infill has been widely used as building material due to its cost effectiveness and availability.  The failure of these masonry infill walls during the past earthquakes have underscored the importance of ensuring the safety of the infill walls when it is subjected to lateral loads. In-plane and out of plane failures have been observed in many reinforced concrete framed building with maso...

ABSTRACT: This paper explores the behavior of infill masonry structures strengthened with a new type of Fiber Reinforced Polymer (FRP) strengthening system with high fracture strain know as PET (Polyethylene Teraphthalate) and a new near-surface mounted (NSM) Carbon fiber strengthening system using a cementitious material as the adhesive as compared to a Glass Fiber (GFRP) strengthening system ...

Masonry infill walls are often used as non-structural elements. According to the past structural failure, ignorance of interaction between infill walls and enclosed frame may lead to the different seismic response for non-ductile building frames. The main contribution of this paper is to analytically investigate the behavior of reinforced concrete with masonry infill panels as participating str...

Abstract: Masonry infill is considered as a non-structural element in all type of buildings where masonry use. But, masonry infill walls are mainly used to increase initial stiffness and strength of reinforced concrete (RC) frame buildings. This Open First storey is also termed as “Soft Storey”. The upper storeys have brick infilled wall panels with various opening percentage in it. In many cit...

This paper describes an experimental program that deals with retrofitting of infill un-reinforced masonry walls (URM) with Fiber Reinforced Polymer (FRP). The primary objective of this research is to develop a retrofit strategy that while economical will minimize the influence of the retrofit on the overall performance of structural frames in predominant seismic regions. Allowing some damage to...
