“…This system characterizes the external visual, customizes the inner rooms, regulates waterproofing, thermic and acoustic insulation, fire safety, and many other factors involved in maintainability and usage [4,5]. Mortar coatings also enhance the mechanical behavior of masonries by slenderness reduction, cross-section increase, and stress distribution [6,7]. Masonry performance can be improved even more if reinforcing meshes are embedded in the coating layer, a technique known for its low cost, ease of execution, and high compatibility with multiple materials [8][9][10].…”

“…Masonry performance can be improved even more if reinforcing meshes are embedded in the coating layer, a technique known for its low cost, ease of execution, and high compatibility with multiple materials [8][9][10]. This procedure provides greater mechanical strength for masonries under multiple load conditions and many studies suggest it is suitable for repair, retrofitting, and reinforcement applications, as well as seismic strengthening of non-structural infill walls [7,[11][12][13].…”

Mortar coatings have a major influence on a building's aesthetics, valorization, and habitability, with significant effects on the mechanical behavior of masonry walls. Multiple types of meshes can be embedded in plaster to enhance both masonry and coating's mechanical behavior, restrain crack formation, enhance the bonding between layers, and increase the wall's seismic resistance. The reinforcement technique has simple execution and is suitable for many applications, including the strengthening of non-load bearing walls, façade performance improvement, and restoration of historical buildings. However, there is an absence of guidelines and specifications for design and execution, resulting in high variability in field applications due to the many variables involved and few in-depth studies. This paper presents a systematic review of the effects of mesh reinforcement in cementitious mortar coatings and its major applications. Mortar and mesh parameters and influences, the status of analytical and simulation models, and suggestions for future research are described.

“…In developing countries, the model of multilevel reinforcedconcrete (RC) frames with infill walls is the most popular type used in housing and business constructions [1,2]. In general, only the weight of the infill wall materials is taken into consideration, and the other strength parameters are ignored.…”

Infill walls are the most common separator panels in typical reinforced-concrete (RC) frame structures. It is crucial to investigate the influence of the infill walls on the earthquake behavior of RC frames. The load resistance of infill materials was often not taken into account in the designing phase, whereas the infill walls have significant contributions to the structural behavior under lateral and vertical loadings. A three-dimensional 4-story RC building is designed, and in order to make a realistic model, different infill walls configurations were taken into account with the openings in the infill. Four different models were created for structural analysis for infill wall effects, namely, full RC infilled frame (Model I), corner infill at ground story RC infilled frame (Model II), open ground story RC infilled frame (Model III), and bare RC frame (Model IV). Static adaptive pushover analysis has been performed for all structural models by using the SeismoStruct software. The double strut nonlinear cyclic model was used for modeling the infill walls. In this study, three different compressive strengths of infill walls are taken into consideration, and the effects on seismic design factors (namely, the response reduction factor, the ductility, the overstrength factor, and the deflection factor) are calculated. The obtained values of the response reduction factor (R) are compared with the given values in the BIS code. The results show that the R factors of all RC infilled frames are decreased when the compressive strength of the masonry infill reduces. However, the R values of bare frames are less than the corresponding values recommended in the BIS code. It is worth noting that the National Earthquake Hazards Reduction Program (NEHRP) provisions underestimate the deflection factors of the reinforced-concrete (RC) frames according to the evaluated deflection factors of the herein studied RC frames.

“…The chained hollow brick masonry infill walls, rigidly bonded to their surrounding frame, are widely used in many countries of the world, especially in our country, and cannot be removed in many processes of execution of reinforced concrete buildings. To know the behavior of these walls in buildings exposed to earthquakes, many researchers and specialists in this field have carried out a lot of experiments several decades ago [1,2] where the results of experiments have been compared to the damage caused by earthquakes. There are also new experimental studies such as [3][4][5][6].…”

The widespread use of masonry infill walls in the most prone zones to earthquakes, for the execution of multistoried reinforced concrete buildings, as well as the recorded damage caused by earthquakes, have forced us to study their influence on the seismic behavior of these buildings. The distribution of masonry infill walls in these buildings is mainly related to their architectural requirements. The purpose of this article is to assess the influence of the various locations of chained masonry walls, which represent a particular type of masonry infill walls without gaps, on multistoried reinforced concrete buildings. This variation has been studied using the SAP finite element software, by the pushover method, analyzing several two-dimensional multistoried reinforced concrete frames infilled by double-leaf hollow brick walls. The proposed frames have been analyzed by varying the position of the chained masonry walls, based on the seismic criteria of the period, elastic base shear, elastic lateral displacement, ultimate base shear, and initial stiffness. The results were compared according to the above criteria. After comparing the results, it is very clear that the position of the masonry walls has a great influence on the seismic response of the reinforced concrete frames. Therefore, it is very important to take into account the position of the infill in the design phase.
