Abstract

Abstrak. Beton bubuk reaktif adalah jenis beton baru yang memiliki kuat tekan ultra tinggi. Komponen penyusunnya adalah powder sangat halus yang memiliki kandungan silika tinggi. Hal ini bertujuan untuk menyempurnakan reaksi yang terjadi pada beton dan meningkatkan homogenitas beton. Beton bubuk reaktif terdiri dari: semen, silica fume, pasir kuarsa dengan diameter maksimum 600 μm, superplasticizer dan serat polypropylene. Penelitian ini bertujuan mempelajari perilaku sambungan balok-kolom eksterior dengan meneruskan dan atau menambahkan tulangan pada sambungan balok-kolom eksterior menggunakan beton bubuk reaktif dengan pembebanan lateral siklis. Penelitian terdiri atas tiga buah benda uji dengan kuat tekan beton bubuk reaktif 135 MPa. Benda uji pertama (BU-1) berupa sambungan balok-kolom konvensional, benda uji kedua (BU-2) sambungan balok-kolom eksterior dengan meneruskan tulangan balok menembus kolom dan menambahkan pelat seukuran penampang balok pada sisi kolom dengan las, sedangkan benda uji ketiga (BU-3) sambungan balok-kolom eksterior dengan menambahkan tulangan pada tulangan pokok balok di sambungan balok-kolom eksterior. Hasil penelitian eksperimental dengan sistem pembebanan lateral siklis benda uji-3 lebih baik dibandingkan dengan benda uji-2 dan benda uji-1 untuk pola retak, kurva histeretik, hubungan antara beban dan lendutan, disipasi energi, degradasi kekuatan, dan degradasi kekakuan pada setiap siklus pembebanan. Abstract. Reactive Powder Concrete is a new type of concrete that posseses an ultra high compressive strength. The primary component of Reactive Powder Concrete is very fine powder with high silica content to improve the concrete’s chemical reaction and its homogeneity. Reactive Powder Concrete is a mixture of cement, silica fume, 600 μm diameter maximum of quartz, superplasticizer and polypropylene fiber. This research aims to evaluate the behavior of exterior beam-column connections with extended beam longitudinal bars and/ or added reinforcement using reactive powder concrete under lateral cyclic loading. This study consisted of three specimens with reactive powder concrete compressive strength of 135 MPa. The first specimen (BU-1) was detailed as a conventional beam-column connection, the second specimen (BU-2) was detailed by extending beam longitudinal reinforcement bars which are welded to a steel plate as large as beam’s cross section to the far side of column, while the third test specimen (BU-3) was detailed by adding reinforcement to the main reinforcement of the beam in the exterior beam-column connections. The results showed that specimen BU-3 possesed better cyclic behavior compared to the other two specimens in terms of crack pattern, hysteretic curve, energy dissipation, strength and stiffness degradation at each loadingcycle.

Abstract

Diagrid also known as diagonalized grid structure have emerged as one of the most innovative and adaptable approaches and have evolved to the point of making its use non-exclusive to tall buildings. The advantage of this system thus even outweight the disadvantages which are specifically the complexity in design, joint connection construction and the high cost of the structure. Therefore studies related to a structure of this kind which has a huge scope in the future are highly desirable. Analysis using linear dynamics of various structures has been carried out in ETABS using the spectrum response method. The analysis results in term of the top storey displacement, inter-storey drift and time period have been compared to understand the diagrid structure system. The first comparison between diagrid and conventional system has been analysed to illustrate the superiorty of the diagrid system. This comparison illustrate the importance of diagrid in reducing various lateral load parameter such as top storey displacement, inter-storey displacement and time period. The value of the top storey displacement for conventional systems in the direction of x dan y is 34,2% and 30.9% higher than the diagrid system. Both system comparison are hybridized with and without shear wall cores. From the results of the shear wall core effect in the diagrid system, it was observed that the shear wall core improved the performance of the diagrid structure. Lateral top storey displacement decreases from 48.2 mm to 43.5 mm so it is reduced by 10%.

Abstract

Terlalu banyaknya permasalahan lalu lintas yang biasanya bertumbuh lebih cepat dari upaya-upaya untuk dapat dilakukan pemecahan dari permasalahan transportasi sehingga berakibat meningkatnya masalah – masalah menjadi semakin bertambah parah dengan berjalannya dan bertambahnya waktu. Untuk dapat memecahkan permasalahan dalam lalu lintas perlu diambil langkah-langkah nyata yang berani atas dasar kajian dan langkah-langkah yang pernah dilakukan di kota-kota lain. Faktor jalan terkait dengan kecepatan rencana jalan, geometrik jalan, pagar pengaman di daerah pegunungan, ada tidaknya median jalan, jarak pandang dan kondisi permukaan jalan, tidak memadainya bahu jalan fasilitas pejalan kaki yang sering diabaikan atau tidak tersedia. Syarat batas tepi pelat yang sembarang atau memiliki kondisi jepit elastis di setiap sisi tepi pelat sesuai dengan persamaan (3.23), (3.24), (3.25), (3.26), (3.41), (3.42), (3.43) dan (3.44), sudah mendekati keadaan sebenarnya di lapangan, terlihat dari gaya-gaya dalam yang terjadi pada pertemuan antar pelat. Kontribusi dari masing-masing ragam (mode) terhadap defleksi dinamik maksimum berkurang sejalan dengan meningkatnya ragam sistem. Mengikutsertakan tujuh buah ragam getar di arah x dan tujuh buah ragam getar di arah y untuk menghitung defleksi maksimum sistem sesuai dengan Tabel 4.5 adalah lebih dari cukup hingga diperoleh defleksi dinamik sistem yang akurat. Konstanta pondasi pendukung pelat k dan Gs jenis tanah pendukung  dengan CBR 5% k=38 MN/m³ Gs=13.3 MN/m dengan variasi nilai redaman struktur pelat mengakibatkan berkurangnya lendutan di tengah bentang  sesuai dengan Grafik 4.2 dan Tabel 3. Hal ini menunjukkan bahwa sistem yang ditinjau semakin kaku. Lendutan dinamik maksimum yang terjadi di pusat pelat untuk parameter beban yang dipilih yaitu : P0=80kN, ωbeban=200 rad/det, Acc=2 m/det2 terjadi pada saatkecepatan kendaraan berada 30 km/jam sesuai dengan Grafik 4.2, Grafik 4.2. Kecepatan ini merupakan kecepatan kritis untuk sistem yang ditinjau. Bila melihat tipe dan kelas jalan maka jalan pada akses industri Karawang masuk pada tipe jalan 2 kelas 3 dan maksimum kecepatan yang diijinkan untuk kendaraan 40.3 km/jam masih dalam batas yang diijinkan.

Abstract

Wood charcoal ash is the result of chemical changes from the burning of wood. Wood charcoal contains silica which is a good binder aggregate for concrete mixtures, it is the same as the function of cement in a concrete mixture. Wood charcoal can also be used as a mixture or addition to the manufacture of reactive concrete. Concrete is a mixture of portland cement, fine aggregate, coarse aggregate and water, with or without additives that form a solid mass. Concrete is prepared from coarse aggregate and fine aggregate. Cement and water interact chemically to bind the aggregate particles into a solid mass (George Winter, 1993). Based on the results of research that has been done, the results obtained on normal concrete of 17.98 Mpa at the age of 7 days and increased at the age of 14 days of 20.73 Mpa, and 28 days of 22.94 Mpa. At the time of normal concrete mixed with wood charcoal ash 3% compressive strength of concrete again increased by 20.43 Mpa at the age of 7 days, but at the age of 14 days of concrete with a mixture of wood charcoal ash increased by 20.82 Mpa and again increased at the age of 28 days by 27.07 Mpa. The decrease continued to occur in concrete with a mixture of wood charcoal ash 8% and 13% at the age of 7 Days, 14 days, and 28 days, the increase in the compressive strength of the optimal concrete is in the concrete mixture of wood charcoal ash 3% at the age of 28 days.
