Abstract
Indonesia yang berada dikawasan cincin api pasifik menjadikan salah satu negara yang rentan terhadap gempa bumi. Oleh sebab itu bangunan direncanakan untuk tidak membahayakan penghuni yang artinya bangunan masih bisa menahan getaran saat terjadinya gempa bumi. Kekakuan pada struktur diperhitungkan untuk membuat struktur lebih aman dan kuat serta membatasi pergerakan struktur. Pengaruh dinding bata merah dalam perencanaan bangunan selain mempunyai nilai estetika pada bangunan, dinding bata juga berperan untuk memberikan kekakuan pada struktur bangunan hal tersebut dapat dibuktikan dari nilai periode yang terjadi struktur portal berdinding X = 0,075 detik dan Y= 0,057 detik dibandingkan dengan portal X = 0,656 dan Y = 0,574. Simpangan maksimum pada portal tanpa dinding arah X = 31,158 mm dan Y= 18,337 mm sedangkan portal berdinding X = 0,204 mm dan Y= 0,112 mm hal ini menunjukan dengan adanya dinding mengurangi simpangan yang terjadi pada struktur. Namun ketika gempa, struktur bangunan akan mengalami klasifikasi dibeberapa tempat sehingga bangunan tidak lagi berperilaku linier melainkan non-linier. Oleh sebab itu dilakukan analisis lanjut untuk mengetahui performance dari struktur ketika nonlinier. Salah satu metode yang digunakan adalah Pushover Analysis dengan bantuan program ETABS. Dalam analisis ini, struktur bangunan didesain dengan dua model yaitu portal terbuka dan portal menggunakan dinding memperhitungkan bukaan. Hasil dari analisis menunjukan displacement yang terjadi untuk portal tanpa dinding arah X = 135,88 mm dan Y= 85,13 mm sedangkan portal berdinding adalah X = 84,01 mm dan Y= 33,76 mm. jadi kekakuan dinding bata merah mempengaruhi kestabilan dan keamanan struktur lebih aman dibanding portal saja. Namun, berdasarkan kedua model bangunan berada pada level Immediate Occupancy (IO) yaitu kerusakan akibat dari gempa sangatlah kecil. Kata Kunci: Bangunan tingkat rendah, Dinding bata merah, Pushover Analysis, Kinerja Struktur, SNI 1726-2019 / Indonesia, which is located in the Pacifik Ring of Fire area, is one of the countries prone to earthquakes. Therefore, the building is planned not to endanger residents. The 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 second and Y = 0,057 second compared to the portal X = 0,656 and Y = 0,574. The maximum deviation of the portal in the direction of X = 31,158 mm and Y =18,337 mm while the walled portal X = 0,204 mm and Y = 0,112 mm 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-liniear. Therefore, further analysis is carried out to determine the performance of the structure when it is non-linear. One of the methods used is Pushover Analysis with the help of the ETABS V21 programs. the building structure is designed with two models, namely an open portal and a portal using walls taking into account openings. The result 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.
