Approximately 85 million people's houses are scattered all over Indonesia, and almost all are in strong earthquake areas. In every earthquake, the houses are generally damaged or collapsed. Therefore, those houses must be strengthened to make them earthquake resistant. This paper discusses a gradual strengthening of existing houses using ferrocement bandaging. The gradual strengthening is introduced due to limited funding of the people. It also serves as an educational tool to educate people to be self-sufficient in building their earthquake-resistant houses. The first step, maybe the sleeping room shall be strengthened so that if there is an earthquake during night-time, people will be safe, and if there is an earthquake during the daytime, people can immediately run to that particular room. A global analysis is made of a sample house shaken by Palu, Central Sulawesi earthquake 2018, and West Sumatra earthquake 2009, with one room strengthened to show that the strengthened room can survive the earthquakes. Then the analysis is continued gradually to the other rooms until the masonry house is fully strengthened by ferrocement bandaging. The results show that the masonry house strengthened by ferrocement layers is earthquake resistant.

“…The government has made efforts to mitigate natural disasters by establishing technical guidelines for earthquake-safe houses (key requirements for safer houses) for the community to create safer buildings against earthquakes. As a technical guideline based on theory, the materials used when constructing simple houses are assumed to have met the requirements for the quality of concrete, reinforcement, and bricks [7].…”

Influence of Firing Temperature on the Mechanical Properties of Bricks

West Sumatra is a province in Indonesia that is known for its high levels of seismic activity. Brick-walled buildings are particularly vulnerable during earthquakes. As the property sector continues to grow, the demand for red bricks in construction is rising. The brick industry in West Sumatra is thriving despite economic pressures. Red brick remains popular among the public, particularly as the main component of walls in simple house buildings. However, each manufacturer uses different raw materials, resulting in varying levels of quality, which still need to meet the Indonesian National Standard (SNI). This research aims to determine which brick composition has the best elemental properties in West Sumatra and investigates the effect of temperature on the chosen brick and its characteristics. The X-ray fluorescence Spectroscopy (XRF) test results indicate that the composition of Pariaman bricks is the closest to the required standards and so they were selected as test specimens to evaluate brick characteristics. The highest compressive strength results were obtained in bricks at a temperature of 800 o C and they also fulfilled the requirements of SNI 15-2094-2000, with a water absorption capacity under 20% of the water absorption rates. Based on the density testing, the increase in the firing temperatures of the specimens increases the bulk density. This is related to the lower porosity of brick at higher temperature firings. The modulus of elasticity was directly proportional to the compressive strength; the higher the temperature, the higher the brick stiffness.

“…The house only has non-structural components such as walls, roof and ceiling. The non-structural component of a simple building is not part of the main load working on a structure, but this component can be the main cause of earthquake losses [6]. Hollow brick has a very heavy material because it is made of mortar.…”

A retrofitting method for hollow brick Unreinforced Masonry (URM) buildings has been developed using ferrocement layers with the bandage system. An experimental study on hollow brick URM houses with and without ferrocement layers was conducted. Two specimens of a quarter-scale hollow brick house model consisting of four walls with the size 104cm x 110cm were constructed. The first model (B1) is the original hollow brick URM house without mortar plaster, and the second model (B2) is the same masonry house retrofitted by providing bandage ferrocement layers on both sides of the walls, which act as sandwich structures. Both specimens were tested by using a shaking table (304x190) cm 2 with input motions from 0.3g to 0.6g. The test results show that the damage to the original URM house model was initially found near the door opening at input motion 0.3g and the applied additional uniform load of 200 kg on the top of the specimen. Then, the cracks were developed and spread to the east side of the wall with the increase of the uniform load, and finally, the house model collapsed at input motion 0.6g and 500 kg additional uniform load. Meanwhile, the hollow brick URM house strengthened by using bandage ferrocement layers shows excellent performance without any damage up to input motion 0.6g. These results indicated that the ferrocement layer significantly enhanced in ductility of the hollow brick URM house model, and it was effective in preventing the collapse of the hollow brick masonry walls when earthquakes happen.
