ABSTRAK

Analisis Pushover merupakan sebuah sarana untuk memberikan solusi berdasarkan Performance Based Seismic Design yang pada intinya adalah mencari kapasitas struktur. Analisis Pushover dilakukan dengan memberikan beban statis dalam arah lateral yang ditingkatkan secara bertahap increment hingga mencapai target perubahan bentuk displacement tertentu.Studi ini membahas tentang assessment kerentanan gedung beton bertulang yaitu analisa tentang hubungan base shear dengan displacement dan kerusakan kerusakan apa saja yang terjadi. Tahap pertama pengevaluasian adalah melakukan evaluasi atau kontrol kapasitas penampang setelah itu melakukan analisis beban seismik atau analisis Statik Nonlinier Pushover dengan program bantu SAP2000. Dari hasil analisis pushover dapat dilihat level kerusakan yang terjadi sehingga dapat dilakukan assessment kerusakan gedung. Penelitian berpedoman pada SNI-1726-2002 dan FEMA 273.Berdasarkan hasil perhitungan numerik yang dilakukan melalui analisis pushover maka dapat disimpulkan bahwa kekuatan gempa yang terjadi berada dalam range antara 100 sampai dengan 120 dari kekuatan gempa rencana hal ini dapat dibuktikan melalui data-data yang didapatkan dari hasil dokumentasi keadaan bangunan pasca gempa dilapangan yang menunjukan bahwa kondisi bangunan pasca gempa berada dalam kategori IO Immediate Occupancy Level. Artinya tidak ada kerusakan yang berarti pada struktur dimana kekuatan dan kekakuannya kira-kira hampir sama dengan kondisi sebelum gempa. Komponen non-struktur masih berada ditempatnya dan sebagaian besar masih berfungsi jika utilitasnya tersedia. Bangunan dapat tetap berfungsi dan tidak terganggu dengan masalah perbaikan.


ABSTRACT

Pushover analysis is a method that provide solutions based on Performance-Based Seismic Design generally is to find the capacity of the structure. Pushover analysis is performed by providing a static load in the lateral direction is increased gradually increments to achieve the target specific deformation displacement. This study discusses the vulnerability assessment of reinforced concrete buildings namely analysis of the relationship of base shear with displacement and any failure that occured.The first step of the evaluation was analyze the seismic loads with Nonlinear Static Pushover Analysis program using SAP2000 software. The pushover analysis results showed the level of damage and then make a building damage assessment needed. This research was based SNI-1726-2002 and FEMA 273. Based on the results of numerical calculations are performed by pushover analysis it can be concluded that the strength of earth quake was in the range between 100 to 120 of the strength of the earthquake plan it can be proved from the documentation of the state of the building after the earthquake which indicates the condition of the building after the earthquake are in the category of IO Immediate Occupancy Level. That is there is no significant damage from structure the strength and stiffness roughly similar to the conditions before the earthquake. Non-structural components are still works if the utility is available. The building still works and do not interfere with repair issues.
