“…It should be noted that several assumptions have been made for the calculations as noted before, such as in-plane failure precedes the out of plane failure based on damage reported in literature [6][7][8]. However, this is not a general rule, and should be taken with precautions especially with masonry infill with gaps around the frames, large openings and masonry walls without bounding frame.…”

“…This paper briefly discusses the results of past experimental studies in order to understand the parameters influencing the shear strength of masonry infill. Figure 3 shows the relation between the shear strength of the masonry infill and the masonry prism compressive strength, fm, based on a database of experimental results from nine different researchers [6][7][8][9][10][11][12][13][14] and details of the experimental results are summarized in [15]. The database consists of single-story, single-span RC frames with masonry infill tested under static cyclic loading with several types of masonry bricks.…”

Many of the buildings which experienced damage in recent earthquakes such as the 2015 Nepal Earthquake were reinforced concrete (RC) frame buildings with unreinforced masonry infill walls. This study proposes a simplified procedure to estimate the in-plane seismic capacity of masonry infilled RC frame buildings based on concepts of the Japanese seismic evaluation standard (JBDPA, [1]). The correlation of seismic capacity and observed damage obtained using a database of 370 existing RC frame buildings with masonry infill that experienced earthquakes in Taiwan, Ecuador and Nepal is investigated. The Is index, which represents the seismic capacity of buildings in the Japanese standard, showed good correlation with the observed damage and proved to be effective as a simple method to estimate seismic capacity. The method was then applied to 103 existing buildings in Bangladesh that have not experienced a major earthquake recently. The results emphasize the necessity for urgent seismic evaluation and retrofitting of buildings in Bangladesh.

“…Along with that, various strengthening methods are used at the strengthening of RC structures. Suzuki et al (2017) investigated that the seismic behaviors of five RC frames with 1/4 scale the masonry infill walls under constant vertical and cyclic lateral load. They used horizontal and vertical stacking of the infill wall as parameters in their experiments.…”

In this experimental study; five RC frames with a scale of 1/5, single spans and two storey were produced so as to reflect the characteristics of existing structures. Two RC frames were used as the reference specimens that without an infill wall and autoclaved aerated concrete blocks (AAC) infilled wall. Three of these RC frames were strengthened as CFS (Cold Formed Steel) drywall system, infill RC shear wall and both external RC shear wall and column jacketing. All specimens produced were tested under reverse cyclic lateral loading and constant vertical loading. Strength, stiffness and energy dissipation capacities of all test specimens are compared with each other. The lateral load carrying capacity and energy dissipation capacities of strengthened specimens have occurred higher than reference specimens. But initial stiffness and stiffness at the max lateral load of specimen strengthened with CFS drywall system have occurred lower than reference specimen with AACW.

Numerical Study on Crack Distributions of the Single‐Layer Building under Seismic Waves

This paper conducts a numerical simulation of the antiseismic performance for single-layer masonry structures, completes a study on crack distributions and detailed characteristics of masonry structures, and finally verifies the correctness of the numerical model by experimental tests. This paper also provides a reinforced proposal to improve the antiseismic performance of single-layer masonry structures. Results prove that the original model suffers more serious damage than the reinforced model; in particular, longitudinal cracks appear on bottoms of two longitudinal walls in the original model, while these cracks appear later in the reinforced model; a lot of cracks appear on the door hole of the original model, and no crack appears in the reinforced model till the end of seismic waves; seismic damage of walls in the reinforced model is obviously lighter than that in the original model; dynamic responses at all observed points of the reinforced masonry are obviously less than those of the original model. Strains at all positions of the reinforced model are obviously smaller than those of the original model. From macroscopic and microscopic perspectives, the computational results prove that the reinforced proposal proposed in this paper can effectively improve the antiseismic performance of the masonry structure.
