Abstract
Perkembangan dari perencanaan bangunan tahan gempa pada beberapa dekade terakhir telah melahirkan suatu inovasi baru yang disebut sistem isolasi dasar. Ada beberapa jenis sistem isolasi dasar yang telah banyak digunakan adalah High Damping Rubber Bearing (HDRB), Lead Rubber Bearing (LRB) dan Friction Pendulum System (FPS). Tujuan dari studi ini adalah membandingkan kinerja HDRB dari beberapa parameter HDRB dan dipilih untuk bahan untuk studi perbandingan pada beberapa parameter tersebut. Digunakan 5 permodelan dengan parameter-parameter isolasi dasar yang berbeda-beda yaitu model A, AS1, dan AS2 dimana model tersebut dikurangi atau ditambahkan parameter stiffness nya, lalu model AES dan ACS dimana model tersebut ditingkatkan parameter control strength dan added elastic stiffness nya. Pada tesis ini digunakan model studi berupa gedung RSI Graha Waron 11 lantai yang terletak di daerah Surabaya dengan kondisi tanah sedang dan akan ditingkatkan lagi jumlah lantainya sebanyak 9 lantai sehingga menjadi 20 lantai pada permodelan. Hasil analisa yang dibandingkan meliputi perpindahan atap, gaya geser dasar, perpindahan antar lantai, dan kondisi kerusakan sendi plastis. Studi ini menggunakan program bantu struktur SAP2000 yang akan membandingkan hasil analisa pushover dengan metode ATC-40 Capacity Spektrum sehingga dapat digunakan hasil performance point sebagai perbandingan. Dari analisa perbandingan pushover dan mekanisme sendi plastis, permodelan dengan peningkatan dua kali lipat control strength dan added elastic stiffness terhadap model A sangat mempengaruhi jumlah sendi platis yang mengalami kelelehan dan juga dalam menentukan performance point akan tetapi peningkatan tersebut tidak terlalu signifikan mempengaruhi simpangan antar lantai atau drift.

In the last few decades, Earthquake-resistant building design has given birth to an innovation called the basic insulation system. There are several types of basic insulation systems that have been widely used, namely High Damping Rubber Bearing (HDRB), Lead Rubber Bearing (LRB), and Friction Pendulum System (FPS). This study aimed to compare the HDRB performance of several HDRB parameters, and it selected materials for comparative studies on these parameters. 5 models are used with different basic isolation parameters, namely model A, AS1, and AS2, where the model is reduced or added to its stiffness parameter, then AES and ACS models, where the model is increased control strength and added elastic stiffness parameters. In this thesis, a study model is used in the form of an 11-story Graha Waron RSI building located in the Surabaya area with moderate soil conditions and the number of floors will be increased again by 9 floors so that it becomes 20 floors in the modeling. The results of the analysis compared include the displacement of the roof, the basic shear force, the displacement between floors, and the condition of plastic joint damage. This study uses the SAP2000 structural aid program, which will compare the results of the pushover analysis with the ATC-40 Capacity Spectrum method so that the performance point results can be used as a comparison. From the comparative analysis of pushover and plastic joint mechanisms, modeling with a two times increase in control strength and added elastic stiffness to model A greatly affects the number of plastic joints that experience fatigue and also in determining the performance point, but the increase does not significantly affect the drift between floors.
