BACKGROUNDBACKGROUND• Indonesia is an earthquake prone area

• Many public houses that were damaged byearthquake

• Technical guidelines for earthquake

resistant houses that circulate in thecommunity has not been tested inlaboratory



3

OBJECTIVEOBJECTIVE

• Knowing the reliability of earthquake-

resistant houses under the technicalguidance that circulate in the community

• Provide recommendations on earthquake-resistant brick house that has been testedto the community
