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. Installation is planned external reinforcement steel rods instead of steel reinforcement Berpenampang circle, but lips steel channel with coherence, and restraints on concrete blocks. Lips channel as reinforcement at the outer edge of the concrete block will replace the concrete reinforcing steel embedded in it, so the distance between the center of gravity in the fiber channel lips pull (bottom) and gravity concrete beams hit area larger. Concrete outer material has a smaller strain values ​​can be replaced with steel. The use of external reinforcement steel in concrete beams lips channel receiving bending loads very interesting study, particularly how to reduce and even negate the slip between the steel and the concrete channel lips.

Abstract

SNI 03-1726-2002 mentions that the seismic requirements for building construction design should be based on 4 accelerograms from 4 different earthquake events. One of them is El Centro (California, 1940). In 2010, Indonesian Earthquake revision team defined a new seismic hazard maps. Those efforts have led to revisalSNI 03-1726-2002, because after 2002, there was earthquakes, whose magnitude was bigger than the estimation before. This study will analyze the spectrum response that will be showed through maps of amplification factor distribution and acceleration spectrum on Semarang city area. From those maps, amplification factor value of El Centro earthquake will be compared to the others (Hector Mine, Kobe, and Loma Prieta). Also the comparison of acceleration spectrum value ( PGA, T=0.2, T=1) that caused by Earthquake El Centro and the others. The last is the comparison of  spectrum response that was the result of this study and the spectrum response from SNI 03-1726-2002.
