Abstract
Steel shear walls are a novel component in the field of construction. It has been of special interest to structural engineers for the reinforcement of steel buildings for the recent decades. Its unique features have attracted more attention, and its features are economical, easy to implement, light weight compared to similar systems, high ductility, fast installation, high energy absorption, and a significant reduction in residual stress in the structure. All the reasons made researchers think about studying its use in the repair of concrete buildings. Because this system has a low weight, it does not add extra load to the structure, and even with its connections, it strengthens the beams and columns around it. The design of this system in concrete buildings does not seem to be economical except in the case of restoration. In this paper, preliminary explanations of the steel shear wall are presented for more familiarity, and in the following sections, the study of reinforcement and repair of concrete structures will be studied and its difference with the low‐yield point will be considered. Finally, the test results will be reviewed. The results of this study show that LYP steel shear panels cause a lot of energy loss and absorption, which is very useful in the safety of buildings exposed to severe earthquakes.
Highlights
In recent years, steel shear wall (SSW) has attracted a considerable attention mainly because of its ability to harness lateral loads arising from earthquake. e new phenomenon has been utilized in construction of new buildings, as well as reinforcement of existing ones, especially in earthquake-prone areas such as the US and Japan
E first panel designed according to MRF has been tested in the absence of reinforcement. e second one was a bracing built by LYP100 steel according to BIB-LYP. e third bracing has been developed by A36 steel according to BIBA36. e forth sample has been developed by a steel shear wall built by LYP100 steel
Final resistance of shear panels built with LYP steel has much to do with loading speed
Summary
Steel shear wall (SSW) has attracted a considerable attention mainly because of its ability to harness lateral loads arising from earthquake. e new phenomenon has been utilized in construction of new buildings, as well as reinforcement of existing ones, especially in earthquake-prone areas such as the US and Japan. As it is easy to disassemble, SSW possesses all good points of other bracing systems [3]. It has suggested good efficiency compared to other bracing systems because of its behavior in the plastic environment, as well as energy absorption. Regarding diversity in materials and junctions, pressures are better balanced against lateral loads in SSWs compared to other resistant structures, such as frames and bracing systems, in which materials are gathered together and junctures are centralized [4]; SSWs suggest a better behavior in the plastic environment. Findings suggested a 25% increase in capacity of SSWs to harness disasters such as earthquake, storm, and explosion, compared to other systems such as moment shear frames (Figure 1).
