Study on the Behavior of a Simple House Partially Retrofitted Using Ferrocement Layers due to Earthquake Loads

Abstract

Earthquakes are a serious threat in Indonesia. Large-scale earthquakes that have occurred, such as the Aceh earthquake (2004), the West Sumatra earthquake (2009), the Lombok earthquake (2018), the Mamuju earthquake (2021), and most recently, the West Pasaman earthquake (2022), which caused many fatalities and damaged infrastructure and building houses, especially houses of the economically weak community. These houses were generally built using adobe bricks using the ½ brick masonry method without structural elements such as columns and beams that do not meet earthquake-safe house standards. In an effort to mitigate earthquake disasters, a strengthening method was developed in this study, namely by using ferrocement layers. In this research, a simple house model with adobe walls with a scale of 1:4 will be made, which will be partially strengthened using ferrocement layers tested on a vibrating table and given an earthquake load. Furthermore, numerical analysis was carried out to validate the results of experimental testing. The results of the tests show that the partial reinforcement has contributed significantly to increasing the shear capacity of the adobe brick walls. This is evidenced by the fact that there were no cracks in the reinforced walls up to the acceleration of the earthquake of 1.5 g, while the other walls of the house that were not reinforced experienced cracks and even collapsed.
