Abstract

Indonesia at the location of the earthquake All building structures must meet the structural requirements, namely stiffness, stability, strength. Review structures before building are built determine whether they meet the requirements Methodology Case studies based on secondary data. from the design consultant  The author analyzes with the help of structure software. The purpose of this research is to make sure the building structure meets the structural requirements before it is built. The author conducted a design review based on the Indonesian Code (SNI) Desain consultant data  , building structure is still twist in shape mode 1 and 2 after checking in software. Then the authors review and improve mainly dimensions, reinforcement columns and add shear walls. As a result of the addition of shear walls and column changes, the structure meets the requirements of strength, stiffness and stability. Building structure does not occur twist in shape modes 1 and 2. That is the role of design structure review before it is built. To increase the stability of the structure at the bottom of the stairs out towards the back is given a retaining wall, overcoming the horizontal direction of active soil pressure, ground water and surface water from the direction of the hill.

Abstract

The owner asks the author to see the condition of the commercial building. The author recognizes that Commercial Buildings do not meet the requirements of the structure of strength, stability, and stiffness. Of the substructure and upper structure of commercial buildings in the business center in Riau Province. Even though they have been built, they do not meet the structural requirements. A thorough analysis is needed from the bottom structure to the top structure. This research aim is strengthening under and upper structure, nothing moving the user and operational — survey methodology with collecting primary and secondary data. Substructure and upper structure data are analyzed for the cause of the damage. The solution is the design and construction stages — design of substructure and upper structure strengthening. The right construction stage applies for an essential role in the success of the construction because the condition of the existing structure from the bottom up is weak. The structural improvement achieved successful results

Abstract

Indonesia merupakan negara berkembang yang terus mengalami perkembangan. Jumlah penduduk Indonesia juga terus bertambah sehingga menyebabkan peningkatan pendidikan, perumahan, dan kendaraan, sehingga menimbulkan kebutuhan akan fasilitas pendidikan dan asrama bertingkat tinggi. Bangunan bertingkat haruslah memenuhi ketentuan ketahanan material pada SNI 2847-2019 dan persyaratan ketahanan gempa pada SNI 1726-2019 yang berlaku. Analisis dilakukan pada bangunan asrama dengan jumlah empat lantai konstruksi beton bertulang dan baja yang terletak di kawasan Gunung Geulis, Bogor. Analisis ini bertujuan untuk mengetahui berapa besar persentase gaya geser yang diterima pada kolom yang disesuaikan dengan persyaratan pada SNI, analisis base plate dan analisis sambungan angkur pada baja. Dalam analisis ini menggunakan software ETABS dengan metode LRFD di input beban mati, beban hujan, beban hidup dan beban gempa. Hasil akhir yang didapatkan dari software ETABS dengan metode LRFD adalah persentase nilai tulangan gaya geser yang diterima pada elemen vertikal, analisis base plate dan analisis sambungan angkur. Berdasarkan hasil yang diperoleh pada persentase gaya geser, dilakukan pembesaran dimensi kolom K1 pada sumbu X dan Y. Setelah penambahan dimensi kolom, tidak terdapat kolom yang over-stressed (OS) dan base plate tidak mengalami perubahan yang besar dibandingkan dengan saat kolom baja menerima beban vertikal yang bernilai konstan dan beban momen yang bertambah besar sedangkan angkur tidak mengalami pembesaran momen dan gaya atau over-stressed (OS).
