<![CDATA[Indonesia, which is located in the Pacific Ring of Fire area, is one of the countries that is prone to earthquakes. Therefore, the building is planned not to endanger residents. The rigidity of the structure is taken into account to make the structure safer and stronger and limit the movement of the structure. The influence of red brick walls in building design in addition to having aesthetic value in the building, brick walls also play a role in providing rigidity to the building structure, this can be proven from the value of the period in which the walled portal structure X = 0.075 and Y = 0.057 compared to the portal X = 0.656 and Y = 0.574. The maximum deviation of the portal in the direction of X=31.158 and Y=18.337 while the walled portal X=0.204 and Y=0.112 and both models are within the safe limit. However, during an earthquake, the building structure will be classified in several places so that the building no longer behaves linear but non-linear. One of the methods used is Pushover analysis with the help of the ETABS V21 program. The results of the analysis showed that the displacement occurred for the portal in the direction of X = 135.88 mm and Y = 85.13 mm while the walled portal was X = 84.01 mm and Y = 33.76 mm. So the rigidity of red brick walls affects the stability and safety of the structure longer than the portal alone. However, both building models are at the Immediate Occupancy (IO) level , which is that the damage caused by the earthquake is very small.]]>
