In this research, four specimens of elastomeric base isolators were tested. They named as A1, A2, B1, and B2. The type A B made from the hyperelastic rubber with hardness 40 60, respectively, according to durometer scale shore A. Prior making isolators, both categories (40 60) tested obtain mechanical properties these types rubbers. testing rubbers carried out following BS EN 15129:2009 requirements. A1 B1 under vertical load. For lateral load tests, double shear tests out. Specimen which...
Lead Rubber Bearing (LRB) has been widely applied for seismic protection of mid and high-rise buildings around the world. Its excellent energy dissipation becomes most important aspect this isolation system thanks to plasticity recovery behavior lead core. Aiming develop a deeper knowledge on LRB’s, 3D detailed finite element (FE) modeling is performed in Abaqus FE software. Some parameters involved model are core hyper-elasticity viscosity rubber material. The material derived from results...
Abstract Indonesia is located in high seismic zones. Therefore, earthquake dissipated devices such as elastomeric base isolator needed to minimize building’s damages when an occurs. In this study, a numerical two-stage analysis was carried out evaluate the behaviour of isolators. First, isolators were modelled finite element software obtain vertical and horizontal stiffness damping values based on local rubber mechanical properties that obtained from previous tests. Second, analysed case...
Most parts of Indonesia are located at high-risk seismic regions. Therefore, it is necessary to seriously consider earthquake in designing the seismic-resistant buildings. One most effective methods reduce impact force introduce use elastomeric rubber base isolation as an damper. a tropical country has many sources raw materials particularly rubber. This can be potential main basic need for producing optimum system. paper determined approach method constitutive low-grade get best fitting...
Jalan Lingkar Utara Brebes-Tegal merupakan jalan arteri primer yang terletak di koridor Pantai Jawa (Pantura) Tengah melintasi Kabupaten Brebes (12,385 km) dan Kota Tegal (4,715 km), ini dibangun dengan tujuan untuk memecah kepadatan lalu lintas terjadi Pusat Tegal. Pada tahun 2010, pembangunan mulai dilaksanakan. Namun pada 2013 kegiatan sementara berhenti karena adanya beberapa permasalahan, salah satunya adalah kondisi tanah sebagian lokasi berupa rawa-rawa tambak sehingga daya dukung...
Commonly, in the design of seismic-resistant building, force-based method has been popularly adopted to distribute effect earthquake forces building structure. This concept uses as an approach simulate impact on a building. To predict lateral structure due earthquake, Direct Displacement-Based Method (DDBM) can be introduced alternative solution. The performance level categorized based its damage level. In this paper, performance-based evaluations were carried out according ATC-40, FEMA 356,...
One way to reduce injuries during an earthquake is determine the probability of as early possible so that rescue mitigation may be carried out. An artificial intelligence-based prediction model using a random forest regression algorithm was developed dataset records in Indonesia from January 1900 2022. The attributes used were date, location, latitude, longitude, hypocenter, magnitude, depth earthquake, maximum peak ground acceleration, modified Mercalli intensity, and site class. label...
Numerous studies have employed computer vision algorithms to analyze images of concrete damage. Therefore, conducting an image processing survey detect damage is very crucial. Thus, algorithm analysis was conducted using various and types data from the last decade. The observed were first concrete, which included surface cracks, hairlines, crack width, patterns, holes, diagonal longitudinal transverse cracks. second part figuring out where roads, bridges, buildings are. third sources like...
Di Indonesia saat akhir November 2022, terjadi gempa berkekuatan 5,6 SR di Kecamatan Cugenang, Kabupaten Cianjur, Jawa Barat. Oleh karena itu, beberapa bangunan kawasan tersebut terkena dampak negatif, antaranya mengalami kerusakan struktural yang parah atau bahkan runtuh total. struktur konstruksi, terutama perumahan dan umum seperti masjid sekolah, harus diperiksa secara singkat bersifat tidak merusak. Tujuan dari pengamatan ini akan menilai akibat mengurangi dampaknya jika susulan,...
Indonesia is highly susceptible to earthquakes, with the southern and western coasts of Java Sumatra being most vulnerable regions. Due this vulnerability, it necessary establish a culture disaster mitigation in fertile heavily populated islands reduce number fatalities economic losses caused by earthquakes. One promising real-world seismic base isolation methods using rubber bearing constructed metal layers. This study aimed examine typical behavior natural compounds subjected various...
The Brebes-Tegal North Ring Road is a primary arterial road located in the Central Java Coast (Pantura) corridor that crosses Brebes Regency (12,385 km) and Tegal City (4,715 km), this was built with aim of breaking up traffic congestion occurred Center City. In 2010, construction began. However, 2013 development activities temporarily stopped due to number problems, one which condition soil at some sites form swamps ponds resulting low carrying capacity affected roads on it. This starts...
Program pemberdayaan masyarakat di Dusun Cigadog, Desa Ponggang, Jawa Barat, bertujuan meningkatkan pemahaman dan kesadaran mengenai pengelolaan limbah peternakan sapi pemanfaatannya dalam produksi biogas melalui teknologi biodigester. Limbah kotoran yang tidak dikelola dengan baik telah menyebabkan pencemaran lingkungan masalah kesehatan wilayah ini. Dengan melibatkan aktif pelatihan penyuluhan, program ini berhasil warga manfaat biogas, biodigester, pengolahan peternakan. Hasil analisis...
Abstract Both the building structure and infrastructure in Indonesia today has increased line with development of planning design regulations. Learning from past, concept continues to be improved ensure safety surrounding environment. The completed needs evaluated for existing structure. In terms examining quality material on structural elements, a test is divided into two types, namely destructive non-destructive. concrete was done by coring tests while non-destructive Ultrasonic Pulse...
As the second largest rubber producer in world, Indonesia has a very potential opportunity to support development of base isolation. Various grades are produced by local manufacturers starting from low high grade rubbers. In study, rubbers were also compared another developing country, e.g. India. The laboratory test results used develop suitable constitutive model for hyperelastic material and then Shahzad et al. Several tests on low-grade have been conducted, namely uniaxial tensile,...
Beberapa peraturan di negara maju mensyaratkan perlunya pemeriksaan bangunan existing tiap kali adanya update baru. Di-Indonesia sendiri belum ada yang mengatur setiap peraturan, namun belakangan Kementerian Pekerjaan Umum dan Perumahan Rakyat (PUPR) menginstruksikan untuk menerbitkan sertifikat laik fungsi (SLF) 5 tahun dimana salah satu persyaratannya existing. Umumnya alasan dilakukan karena umur bangunan, perubahan kerusakan akibat gempa. Pada Studi kasus ini industri dibangun 1990, maka...
Konsep desain penggunaan karet peredam gempa adalah energi disipasi, yaitu penyerapan gaya sebelum masuk ke bangunan dengan cara pemisah struktur diatasnya dari tanah yang merupakan pusat sumber kedatangan gempa. Aspek keamanan pelaksanaan pembangunan terutama untuk perumahan rakyat seringkali terabaikan. Hal ini berkaitan pendetailan tulangan baja aspek penting dalam kriteria tahan kerap kali terabaikan di baik secara tidak disengaja maupun dalih menekan biaya agar nilai lebih ekonomis....
Carbon fiber reinforced polymer (CFRP) is a material that can be used to strengthen building structures. This study aims test two CFRP types, CFRP-A and CFRP-B, for structural strengthening. an imported product, while CFRP-B locally produced product with more than 40% domestic content. Using local materials in reduce costs strengthening In this study, of beam elements B was carried out, where there increase the shear strength existing structure by 31.147% 25.154%, respectively. addition,...
