Abstract

Disaster mitigation due to seismic load (earthquake) needs to be considered. This is especially for dam structure used as a reservoir and water resource. Because of the main function, and building dimension is too large, thus if the dam collapse it will cause a significant catastrophe for the surrounding community and environment. One of the seismic damages to the dam is deformation. This paper presents the effect of seismic load on deformation of dam model simulation. This study took place on the Sermo Dam, Yogyakarta which is located close to Opak Fault –as the suspicious cause of the earthquake in Yogyakarta. Seismic loads used in this study in terms of acceleration time histories. Therefore model can be carried out using PLAXIS simulation. This selected seismic load variations are on the range 5.0-7.0 Mw and epicentrum distance is also restricted in 15-31 Km based on the nearest epicentrum distance between Sermo Dam and Opak Fault. Keywords: seismic load, deformation, dam, modeling

Abstract

ABSTRAKIndonesia merupakan salah satu negara yang dilalui oleh cincin api sehingga negara ini sering dilanda gempa. Indonesia juga diapit oleh 3 lempeng yaitu lempeng benua Eurasia, Indo-Australia dan lempeng Pasifik. Gempa yang terjadi dapat berupa gempa tektonik maupun gempa vulkanik. Guncangan dari gempa tersebut dapat merusak struktur bangunan. Maka, perlu diadakan penyelidikan mengenai ketahanan suatu bangunan dalam menerima guncangan gempa. Ketahanan suatu bangunan dapat dilihat dari struktur kolom dan pondasi karena jika struktur tersebut hancur maka struktur bangunan akan roboh. Ketahanan struktur bangunan terhadap gempa bumi disebut uji sensitifitas bangunan. Studi ini dilakukan untuk mengukur ketahanan bangunan terhadap gempa dengan jarak dan kekuatan gempa tertentu dengan menggunakan gempa riwayat waktu. Pada studi ini telah dilakukan pengujian tiga bangunan di kota Semarang. Bangunan tersebut adalah Semarang Medical Center mewakili tanah lunak, Training Center II undip mewakili tanah sedang dan City One Hotel mewakili tanah keras. Gempa riwayat waktu yang digunakan berkuatan 6 – 7 Magnitude momen (Mw) dengan jarak yang bervariasi. Berdasarkan hasil studi ini maka dapat diketahui ketahanan suatu bangunan terhadap guncangan gempa dengan kekuatan 6 – 7 Mw dan jarak tertentu.

Abstract

SNI 1726- 2012 has been implemented and used as basic guidance for earthquake-resistant building design. This regulation replaced RSNI 1726- 2002 which is not suitable for Indonesia’s area that always undergoes earthquake. Siloam Hospitals Medan Building was designed by RSNI 1726- 2002. This journal describes the result of Siloam Hospitals Medan Building’s calculation by SNI 1726- 2012. Structural analysis of Siloam Hospitals Medan Building is calculated by SAP2000 software. The outputs are internal forces which are used to calculate the dimension of structure and bar which is needed. This structure uses the method of Special Moment Resisting Frame  which is expected that it has a high ductility due to its location where is in soft soil earthquake risk area.

Abstract

City One Hotel lies at Veteran road, Semarang city. This hotel is built at less large area so vehicle come in and sticking out floor basement becomes distress. This redesign change distance between columns from 6 meters become 8 meters, so vehicle comes in and sticking out floor basement become easier. Redesign of the Structure of City One Hotel is make parking area more wider. Parking area from first design only use 1st basement and 2nd basement, meanwhile result of redesign use 1st basement, 2and basement and 2bth basement. First design of City One Hotel used Double System with Intermediate Moment Resisting Frames (IMRF), meanwhile redesign use Double System with Special Moment Resisting Frames (SMRF) for it structure system. This redesign based SNI 1726-2012, and value of earthquake parameter response was download from website of Ministry of Public Work for Semarang City. In order to easier modelling and building structure analysis, redesign of City One Hotel are helped by SAP.2000 version 12 and CSI Col progam. The other differences between first design and redesign’s result is cross-sectional shape of the column and sectional area of the beam. First design use rectangular cross-sectional shape column, meanwhile redesign use square cross-sectional shape column. Benefit of square cross-sectional shape column is moment of inertia equally strong for both sides. The redesign’s beam sectional area is wider than before, this is because increased load on beams comparable with increasing distance between columns.

Abstract

To perform the necessary analysis of wave propagation subsurface soil data are complete and accurate. Data were obtained directly from the field geotechnical surveys and obtained from laboratory tests on soil samples taken from beneath the surface through bore hole. Dynamic soil properties determined indirectly from the results of static testing in the field, the Standard Penetration Test (SPT) and Cone Penetration Test (CPT). Several researchers have conducted studies and generate empirical correlation between shear wave velocity (vs) with SPT N-values and CPT cone resistance (qc) such as Imai (1977), Imai & Tenouchi (1982), Ohta & Goto (1978), and Sykora & Stokoe (1983). Using data from the soil investigation reports of 85 locations spread across the Semarang city, consisting of 156 boring point, 83 point manual CPT, and 96 points machine CPT. To determine the site class parameters using weighted average method of N and vs value for 30 meters topsoil profile. The results of this study become soil properties map ( QUOTE   and  QUOTE  ), and site-class map of Semarang city. Based on two (2) soil properties, soil classification in Semarang divided into two site-class, stiff soil (SD) and soft soil (SE). SE site-class commonly found in the north coast side of Semarang city, while soil SD site-class found in the south side of Semarang city.

Abstract

ABSTRAKS   Pengujian balok beton eksternal ini menguji tentang pemanfaatan tulangan eksternal sebagai pengganti tulangan pada beton. Pemasangan baja tulangan eksternal direncanakan bukan dari batang baja tulangan yang berpenampang lingkaran, melainkan baja lips channel yang memiliki lekatan, dan pengekangan pada balok beton. Lips channel sebagai perkuatan di tepi luar balok beton akan menggantikan baja tulangan beton yang tertanam di dalamnya, sehingga jarak antara titik berat lips channel di serat tarik (bawah) dan titik berat daerah tekan balok beton lebih besar. Material terluar beton yang memiliki nilai regangan yang lebih kecil dapat tergantikan dengan baja. Penggunaan tulangan eksternal baja lips channel pada balok beton yang menerima beban lentur sangat menarik diteliti, khususnya cara mengurangi bahkan meniadakan slip antara baja lips channel dan beton. Mutu beton rencana adalah f’c 45 MPa (K500) dengan panjang uji benda 180 cm, lebar 12,5 cm, tinggi 18,5 cm. Kata kunci : Baja Lips Channel, beton bertulang, Slip   ABSTRAKS   Testing of concrete beams externally tested on the use of external reinforcement in concrete reinforcement instead.
