“…A large part of the research studies, found through investigations, has been devoted to preearthquake retrofitting. For example, Kassem et al [12] studied the mechanical behaviors of single-story brick masonry in-filled frames under the effect of lateral loads; Baloević et al [13] investigated the effect of plaster on the performance of single-story single-bay masonry-infilled steel frames under in-plane base acceleration using a shake-table; and Messali et al [14] proposed a pre-earthquake retrofitting for a masonry typology widely used in social housing.…”

The post-earthquake retrofitting and repair process of a building is a key factor in improving its seismic capability. A thorough understanding of retrofitting methods and processes will aid in repairing post-earthquake buildings and improving seismic resilience. This study aims to develop a visualization framework for the post-earthquake retrofitting of buildings which builds models based on building information modeling (BIM) and realizes visualization using augmented reality (AR). First, multi-level representation methods and coding criteria are used to process the models for a damaged member. Then, an information collection template is designed for integrating multi-dimensional information, such as damage information, retrofitting methods, technical solutions, and construction measures. Subsequently, a BIM model is presented in three dimensions (3D) using AR. Finally, the visualization process is tested through experiments, which demonstrate the feasibility of using the framework to visualize the post-earthquake retrofitting of a building.

“…By using the unreinforced cement mortar, traditional retro tting methods improve the tensile strain capacity of the tested specimens by less than 0.015% and increase the bearing capacity of the specimens by a maximum of 3.5 MPa. The primary advantages of using polymer bers include the ease of execution, no increase in the weight of the structure [10], and improvement of the energy dissipation of masonry walls [11]. Despite the mentioned advantages, the use of FRP in strengthening and retro t is subject to such drawbacks as inability to be used on wet surfaces, reduced performance at high temperatures and in alkaline environments (which are an integral part of masonry structures), inevitable potential hazards for workers, and the incompatibility of resin with the masonry materials.…”

This paper proposes a strengthening method for improving the seismic performance of Unreinforced Masonry (URM) brick walls. What is noteworthy regarding the proposed technique is the low price and easy application of polypropylene (PP) bands, which are widely used in the packaging industry. Three half-scale specimens were tested under cyclic lateral loading simultaneously upon imposing a constant vertical load. First, the URM wall was tested up to a certain drift in which a reduction in lateral capacity was recorded. According to the crack pattern observed on the wall surface, a repair strategy was taken to upgrade the damaged wall in the shortest possible time and with minimum manpower. In doing so, horizontal PP bands were employed to wrap the wall. The repair technique stopped the spread of cracks and prevented reduction in lateral capacity. Besides, the third specimen, which is identical to the URM wall but is strengthened by PP bands, was tested and it developed a superior performance by changing the failure mode and increasing the maximum strength, the strength at maximum displacement, and maximum displacement by 88%, 38%, and 185%, respectively, compared to URM wall.
