Many studies have been conducted in recent years to determine how well buildings handle lateral forces. However, the location of the shear wall when a building is subjected to lateral force was not thoroughly studied. It is well known that performance-based design is the best method for determining the ideal location. Pushover analysis is used to find the best location for this study. When conducting a pushover analysis, the relationship between base shear and roof displacement is typically depicted in the capacity curve. Various shear walls are placed throughout the building as part of this analysis to determine the exact location. The PushSW6 model had the highest shear carrying capacity out of 13 models tested, making it the best option for placement. When compared to the model without a shear wall, the shear carrying capacity of the PushSW6 model is 76.66% higher. From here, it is clear that PushSW6's shear walls will be the best location out of the 13 models.

“…The main ingredient is a mortar made of cement, aggregate, and water, to which other ingredients in the form of foam agent are added. Lightweight concrete is a brittle, porous cement paste with uniform micro-air cells distributed evenly throughout the mixture [9,10]. Figure 1 shows a lightweight concrete partition.…”

Examining the crack pattern of lightweight concrete under compressive and tensile loads is the goal of this study. A lightweight concrete specimen was made using foam, fine aggregate, and Portland Composite Cement. Foam agent and water are combined in a 3:10 ratio to produce foam. There were three different foam volume variants used: 15.7 liters, 25.12 liters, and 37.68 liters. As a sample, a cylinder with dimensions of 10 cm by 20 cm was employed. Using compressive and indirect tensile strength tests at curing ages of 3, 7, and 28 days, the crack pattern of lightweight concrete was assessed. The findings revealed that the fracture pattern for the compressive and indirect tensile strength tests was almost same; because the crack pattern was parallel to the direction of the load, it was categorized as a columnar crack pattern at 3, 7, and 28 days. Throughout time, the frequency of crack patterns in lightweight concrete decreased. It might be said that concrete becomes more resistant as it ages.

“…There are usually randomly distributed bubbles in its mixture, and the concrete is characterized by high flowability, less cement usage, and more efficient aggregate application. The application of foam concrete as infill walls in RC frames has the ability to reduce the weight of the frame, and this has a valuable influence on structural global performance [7][8][9][10][11].…”

An experimental study was undertaken to examine the behavior of RC-frames employing precast foam concrete reinforced with diagonal CFRP as an infill wall under ASTM E2126-02a cycle testing methodology (ASTM 2003) in order to anticipate the onset of earthquake-related disasters. The study aimed to determine the failure rate and mechanism based on FEMA 356. An RC frame with precast foam concrete acting as an infill wall without retrofitting (WTI) and an RC frame with precast foam concrete acting as an infill wall and CFRP retrofitting at a width of 36 cm (WTC) were constructed as two different types of examples. The results showed that whereas the WTI produced a maximum load value of 44.88 kN at push loading and 52.30 kN at pull loading, the WTC produced a maximum load value of 102.87 kN at push loading and 80.09 kN at pull loading. The diagonal CFRP retrofitting increased the RC frame's capacity to support in-plane horizontal cyclic stresses when foam concrete precast was used as an infill wall. The test specimen with the CFRP retrofitting underwent a shear failure that started with the CFRP strip debonding and ended with a shear structural collapse. The infill wall had an in-plane failure and a diagonal crack with shear collapse. This demonstrates that the maximum load that the RC specimen could withstand after being retrofitted with CFRP rose for each structural performance grade.
