“…In the seismic design of reinforced concrete houses, in addition to rational structure selection and correct structural measures, more attention should be paid to conceptual design. e goal of the dual-line-of-defense seismic design of super high-rise buildings is to make the overall structure play a role in dissipating seismic energy, avoiding sensitive weak parts of the structure, leading to premature failure of super high-rise buildings [6][7][8].…”

In order to improve the safety performance of supertall buildings under earthquake, a seismic performance analysis method of double lines of supertall buildings based on a response surface optimization algorithm is proposed. Firstly, the structural performance indexes of super high-rise buildings are selected, and on this basis, the material constitutive model is constructed by the structural elastic-plastic analysis method to complete the seismic design of the first line of defense. Then, the response surface method is used to optimize the material constitutive model and complete the seismic design of the second line. Finally, the anticollapse limit state analysis method is used to determine the seismic performance of the double line of super high-rise building structures. The experimental results show that the proposed analysis method has high seismic performance, and the axial compression ratio of wall and column is always stable, in which the column is always at about 0.5 and the wall is always at about 0.26, which lays a foundation for the safety performance of super high-rise building structures under earthquake.

“…Five distinct in-plane failure mode categories are identified in the infilled frames [19]. Firstly, frame failure modes consist of the formation of plastic hinges in the beams and columns near the joints, the failure of beam-column joints, or, in very few cases, at the column mid-height.…”

The treatment of masonry infill walls as non-structural elements in the design of reinforced concrete buildings has been refuted by the losses and damage recorded when these buildings were exposed to seismic loads. Between these walls, there is a type widely used in reinforced concrete buildings in Algeria. This article aims mainly to highlight the role of the infill masonry walls in improving the seismic response of reinforced concrete buildings to resist seismic loads. To demonstrate the above role, we have analyzed several models of two-dimensional frames of a multi-storey building located in a high seismic site, according to the classification of the current Algerian seismic code, with double-leaf hollow brick masonry, which is the most used infill material in Algeria. This analysis is based on the response spectrum method using the finite element software ETABS, taking into account the most important requirements of the current Algerian seismic code. We used the parameters of period, base shear, maximum displacement, and stiffness to evaluate the ability of these frames to respond to seismic loading; we analyzed several models in terms of the number of storeys. After analyzing all the models, we compared the results obtained, and then we were able to define this role and see what contribution these walls can make to the analytical aspect. Finally, we were able to know the positive role that these walls can play in improving the seismic performance of this type of building.

“…The last of the approaches that is more precise is the micro-model, which is summed up by considering all the details of the masonry infill wall of the mortar, blocks, whether concrete or brick, as well as the interaction between the wall and the surrounding frame [16,19]. In the following section, we have carried out a parametric study by analyzing several models of a two-dimensional multistoried reinforced concrete frame using the nonlinear static pushover method « pushover ».…”

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.
