Experimental work on seismic behavior of various types of masonry infilled RC frames

Full-scale experimental study on masonry infilled RC moment-resisting frames under cyclic loads

“…The experimental results obtained by Stylianidis [7] indicated that the ratio of the initial stiffness of the frames infilled with hollow clay brick block masonry to that of the bare frame is about 4.2-5.3. Misir et al [6] pointed out that in the elastic range, the stiffness of the specimen infilled with solid clay brick masonry is 5.33 times larger than that of the bare frame. According to the test results obtained in this study, the initial stiffness of the RC frame infilled with aerated concrete block masonry and rigid connection is 6.7 times that of the bare frame, while the ratio of the initial stiffness of infilled frames with flexible connection to that of the bare frame is 1.35-2.02.…”

“…Compared with the frame infilled with hollow clay brick blocks, the frame infilled with aerated concrete blocks has smaller lateral strength but exhibits better hysteretic behavior. Misir et al [6] performed an experimental research work on RC frames with standard and locked bricks and found that locked brick infills have improved out-of-plane stability compared with the standard bricks. Stylianidis [7] introduced three successive experimental programs conducted on RC frames infilled with perforated clay brick block masonry and found that the contribution of the infills to the strength, stiffness and energy dissipation capacity depends on the strength of the infill wall in relation to that of the frame.…”

Seismic Performance of a New Type of Fabricated Tie-Column

“…Many experiments have been conducted and proved that the presence of infill walls significantly increases the strength, stiffness and seismic energy dissipation capacity of buildings [1][2][3][4]. Besides, experience from actual earthquakes suggests that properly constructed infill walls might inhibit the collapse of inadequately designed or insufficiently detailed structural systems [5,6].…”

Simplified Modeling of Masonry Infill Walls With Horizontal Sliding Joints

“…The proposed solutions reached the aim with different approach: (i) partitioning of the infill wall [10]- [16]; (ii) adopting alternative joints instead of mortar (dry or plastic joints) [17]- [21]; (iii) using deformable materials for the construction of the infill [22], [23].…”
