Parametric Study Performance of Red Brick Fillers in Reinforced Concrete Structures due to Earthquake Loads

Introduction

In the world of construction, the filler walls made of red bricks are often seen as additional burdens that are channeled into building structures. This assumption results in the impact of the strength and stiffness of the filler walls not calculated in building planning. Generally, structure planning assumes buildings as an open frame structure where non-structural brick walls function as a burden of gravity that works on the beam. However, in reality, this filling wall can significantly affect the behavior of the structure of the building itself.

The importance of understanding the role of filler walls in building structures cannot be overstated, especially in regions prone to earthquakes. Earthquakes can cause significant damage to buildings, leading to loss of life and property. Therefore, it is essential to design buildings that can withstand earthquake loads and minimize damage. This thesis aims to explore how much influence the stiffness, strength, and configuration of brick walls on the whole structure.

Methodology

In this study, the building structure was modeled as a two-dimensional portal and consisted of five models, namely:

Open Frame Structure: This model represents a traditional building structure with no filler walls.
Fully-Infiled Wall Frame Structure: This model represents a building structure with a fully-filled wall made of red bricks.
Fully-infiled Wall Frame structure with 16% openings: This model represents a building structure with a fully-filled wall made of red bricks, but with 16% openings.
Fully-infiled Wall Frame structure with 40% openings: This model represents a building structure with a fully-filled wall made of red bricks, but with 40% openings.
Open First-Story Frame Structure: This model represents a building structure with an open first-story frame and a fully-filled wall made of red bricks on the upper stories.

Results

The results of the analysis show that the contribution of the filler wall made of red brick greatly affects the lateral stiffness of the structure. In this case, the presence of a rigid filler wall at one level, while other levels do not have a filler wall, can cause a weak level of level (soft story). This shows that uneven distributing wall distribution can reduce the overall stability of the structure.

Furthermore, this study also revealed that the opening on the filler wall had a significant effect on the strength of the wall. Walls with a 40% opening show that there is no significant impact on the performance of the main structure. In this case, the choice of configuration and opening size is very important to maintain the strength of the wall without sacrificing the integrity of the building.

Discussion

The installation of red brick filling walls can increase structural capacity. This study shows that the structural model with the filler wall has a greater capacity, with an increase of 12.833% in the earthquake zone 4 and 28.931% in the earthquake zone 6. While for models with a opening of 16%, there is an increase in capacity of 3.015% in the earthquake zone 4 and 7.135% in the earthquake zone 6.

However, it is essential to note that although the existence of the filler wall can increase the capacity of the structure, this is also inversely proportional to the structural ductility. The study found that there was a reduction in ductility to 56.344% in earthquake zones 4 and 7.405% in earthquake zones 6. This shows that although the structure is stronger to lateral loads, it may become less flexible, which can be at risk in a very strong earthquake situation.

Conclusion

In order to improve the safety and performance of buildings, more precise planning regarding the filler wall is very important. Taking into account factors such as stiffness, strength, and configuration of brick walls, architects and civil engineers can design structures that are not only strong but also safer in dealing with earthquake disasters. In the future, this research is expected to provide valuable insights for better earthquake-resistant building planning, as well as educating the public about the importance of the role of the filler walls in the overall design of the structure.

Recommendations

Based on the findings of this study, the following recommendations are made:

Incorporate filler walls in building design: Filler walls made of red bricks can significantly affect the behavior of the structure of the building. Therefore, it is essential to incorporate filler walls in building design to improve the safety and performance of buildings.
