Abstract

Abstrak. Sistem isolasi seismik yang tersedia dewasa ini menggunakan teknologi canggih dan umumnya digunakan pada bangunan berlantai banyak. Penelitian ini mengkaji karakteristik isolasi bola baja yang sederhana tetapi diharapkan handal untuk bangunan rumah. Beban bangunan dimodelkan sebagai massa tunggal dan meja getar memodelkan tumpuan dasar (base). Isolasi bola dipasang di antara massa dengan meja getar. Rumah bola dibuat dua macam yaitu berbentuk tabung belah dan ½ bola. Beban siklis diaplikasikan pada meja getar dengan amplitudo 5, 10 dan 20 mm, frekuensi 151 dan 240 cpm. Friksi dalam sistem isolasi diukur. Respons massa dalam gerakan satu arah direkam pada kertas skala. Hasil penelitian menunjukkan bahwa semakin tinggi percepatan meja getar am, semakin besar persentase redaman percepatan yang dirambatkan ke massa. Dalam rentang parameter input yang diaplikasikan, untuk rumah bola berbentuk tabung belah, redaman percepatan mencapai 92% sampai dengan 99 %, sedangkan untuk rumah bola berbentuk ½ bola mencapai 35% sampai dengan 92 %. Rumah bola berbentuk tabung belah jauh lebih efektif meredam percepatan dibandingkan dengan rumah bola berbentuk ½ bola, dengan angka perbandingan respons percepatan massa 1:7 sampai 1:8. Abstract. Seismic isolation systems being available recently are sophisticated technology and commonly used to reduce multi-storey building response from seismic ground motions. The simple steel ball isolation was conducted to predict the reliability of housing structures in response of seismic ground motion due to earthquake. To develop a model, the building loads are assumed as a single mass system and a vibration table as a supporting base. The steel ball isolation was installed between the mass and the table. Two houses shapes are made, that is, a split cylinder and an half ball. Sinusoidal forces were applied on vibrating table with the amplitudes of 5, 10 and 20 and the frequencies of 151 and 240 cpm. Frictions in the isolation system were measured, while movements of mass responses based on one direction displacement were recorded on scaling papers. This research reveals that the higher the vibrating table acceleration (am), the higher the percentage of  damping spreads through the mass. In the range of the application of input parameters, the accelerations are reduced from 92% to 99 % for split cylinder ball’s house, and from 35% to 92 % for half-ball ball’s house. The split cylinder-ball house is much more effective to reduce acceleration than the half-ball house. Those ratios of mass acceleration responses are from one eighth to one seventh.

Abstract

Abstrak. Keruntuhan gedung akibat gempa masih menjadi masalah yang perlu dipecahkan. Penelitian ini mempelajari kinerja isolator seismik bola-pegas pada model struktur fleksibel satu lantai skala kecil. Massa model pada level atas dan bawah masing-masing 30 kg. Bola isolator dipasang di antara model struktur dan landasan getar. Pegas dengan konstanta 500N/m dipasang untuk memulihkan model ke posisi semula pasca getaran. Satu ujung pegas diikat pada setiap sudut bawah model dan ujung lainnya diikat pada landasan getar. Kolom dari model dengan konstanta pegas 22117 N/m, dijepit pada ujung atas dan bawah. Getaran sinusoidal diaplikasikan pada landasan getar dengan frekuensi 10.6, 15.35 dan 20.44 rad/s serta amplitudo 5, 10, 15 dan 20mm. Hasil penelitian menunjukkan bahwa respons percepatan model as, meningkat secara linier terhadap peningkatan percepatan landasan am, sedangkan rasio respons percepatan model terhadap percepatan landasan (as/am) berkurang seiring dengan peningkatan percepatan landasan. Isolator bola-pegas sangat efektif mereduksi percepatan terutama pada percepatan landasan yang relatif tinggi. Pada percepatan landasan rendah (0.05g),rasio reduksi percepatan (am-as)/am, mencapai 39% pada level atas dan 45% pada level bawah, sedangkan pada percepatan landasan lebih dari 0.2g, rasio reduksi percepatan tersebut mencapai lebih dari 80% pada kedua level.Abstract. The collapse of buildings due to the earthquake is still an issue that needs to be solved. This research studied the performance of the ball-spring seismic isolator on a reduced scale, single-story, flexible structure model. Model’s mass on each top and bottom level is 30 kgs. Ball isolator is mounted between the structure model and vibrating base. A spring constant support of 500N/m is installed to restore the model to its original position after the vibration. One end of the spring is tied to each bottom corner of the model and the other end is tied to the vibrating base. The column of the model with the spring constant of 22,117 N/m, are clamped at the lower and upper ends. Sinusoidal vibrations were applied on vibrating base with the frequencies of 10.6, 15.35 and 20.44 rad/s and the amplitudes of 5, 10, 15 and 20 mm. The results show that the model acceleration response rates (as) increase linearly to increasing the base acceleration rates (am), while the ratio of the acceleration responses model to the base acceleration (as/am) decreases with an increasing the base accelerations. Ball-spring isolators very effectively reduces acceleration especially at the level of high rates of the base acceleration. At the level of the lower base acceleration (0.05g), acceleration reduction ratios, (am - as)/am, reach 39% at the top level and 45% at the bottom level, while the base acceleration of more than 0.2g the acceleration reduction ratios reach more than 80% at the both level.

Abstract

Penurunan konsolidasi merupakan satu masalah pada lapisan tanah lunak. Penelitian ini hendak menganalisis potensi penurunan konsolidasi di Kalukubula dengan menggunakan teori konsolidasi 1-D dari Terzaghi. Lokasi ini memiliki lapisan lunak yang mencapai ketebalan 16 meter. Hasil penelitian menunjukkan bahwa potensi penurunan konsolidasi total mencapai 8 cm pada titik pusat areal, untuk beban merata di permukaan tanah sebesar q=0,5 kg/cm2 dan sebesar 24 cm untuk q sebesar 1 kg/cm2. Derajat konsolidasi rata-rata 50% tercapai dalam 11 tahun dan 90% setelah 36 tahun

Abstract

The condition or shape of location of construction is often present in a non-flat terrain. Excavation and dumping of soil usually required in this condition that will result on formation of the slope. The slopes can be made steeper with the help of reinforcement such as by using geotextile, steel and other materials. For small or medium scale construction palm fiber sheet can be used as alternative material. Palm fibers are natural organic fibers that have beneficial properties such as resistant to the influence of solar heat and cold weather, resistant to weathering, and not easily rotten and durable so  it can be used as an option for use as a construction material.This study aims to study the potential use of palm fibers as an alternative material for reinforcement material, especially on the slopes. Palm fibers material used in this research are materials that form a natural fiber sheet. The slope model is formed in a test tub with a width of 30 cm and a height of 80 cm. Sand from Pondo River with 50% of relative density is used as slope forming material.The results showed that the reinforced slopes with fiber sheets with 20 cm vertical spacing and 100 cm length of reinforcement on the test model were able to carry a load of 40 kN at 25 mm (1 inch) settlement, and reach 60 kN at 37.5 mm ( 1 ½ inches) settlement

Abstract

The penatration resistance using DCPT on a type of soil are influenced by density and moisture content. The aim of this research is to experimentally study of cone penetration resistance (qc) friction ratio Rf ), dry density (γd) and water content (w) relationship on silt. The silt sample taken from Tondo, Eastward of SMUN 5 Palu. The penetration test are worked on several γd and w variation. Test result showed that the higher the water content, the higher the friction ratio Rf but the lower the qc. At low w, the higher the γd the higher the gradient qc/w. At hight water content, rising up the γd have no significant influence to the gradient qc/w

Abstract

The DCPT penatration resistance on each type of soil has a specific characteristic. The aim of this researchis to experimentally study of DCPT penetration resistance (qc and Rf) of sand for several water content (w)and dry density( d ) variation, and comparison with the same parameter of silt. The sample of sand takenfrom Palu-1’s bridge upstream. Test result showed that the variation of “w” have no significant influencefor qc and Rf. The higher thed the higher the qc and Rf. The specific relation of qc, Rf , w and d of sandin comparison with silt by using charts are veryclear and usefull to interpret the soil type
