Abstract

I cross-section of reinforced concrete reduces weight and concrete needs, but the reduction in strength is not considerably large. In addition, I section reinforced concrete beam is relatively complicated and takes much longer time for manufacturing. Another geometric cross-section which results in equivalent weight reduction with that of I cross-section concrete beam may be hollow square crosssections of reinforced concrete beams. This research was conducted to identify and compare the behavior of the shear and dynamic effects of hollow core reinforced concrete beam with an I cross-section beam that equivalent with its. The specimens being tested were four reinforced concrete beams, of 2000 mm length, consisted of a T beam with bottom flange as control beam (BK) possessing dimensions of bfa = 600 mm, bw = 125 mm, bfb = 200 mm, h = 300 mm, tf = 100 mm, and three hollow core T beams as tested beam (BB1, BB2 and BB3) possessing dimensions of bf = 600 mm, bw = 200 mm, blubang = 75 mm h = 300 mm, tf = 100 mm. Static loading was applied by means of a hydraulic jack in a four-point loading system, were. Dynamic loading test was carried out by vibrating the beams to obtain the natural frequency, where the vibrating load were produced by a mechanical vibrator. Whilst the data on the static load carrying capacity was recorded at the first crack and at each initial additional crack until the ultimate fracture, those on dynamic loading was recorded on the solid block, at the first crack and at yield. The parameters being used was the magnitude of deflection, strain of the reinforcing steel and concrete, crack pattern and natural frequency. It can be concluded that the hollow core reinforced concrete beam can be used as an alternative to I section reinforced concrete beam. It was noticed that the difference in shear load carrying capacity between control beam (BK) and hollow beam (BB) was not considerably significant, where the difference between BK (299.3 kN) and BB1 (337.6 kN) is 12.79%, that with BB2 (350, 6 kN) or 17.14%, and that with BB3 (289.4 kN) or −3.31%. The natural frequency of BK is 58.594 Hz, 15.769% larger than the natural frequency of BB3 with 49.354 Hz. The natural frequencies of tested beam decreased with the increased of damage to the beam.

Abstract

The traditional society of south borneo has a traditional form of building foundation that has been used for a very long time for their traditional house. This is called Kacapuri foundation that use a combination of Ulin wood and Galam wood. But right now because the lack of Ulin wood, this form is  not familiar anymore in south borneo.The rising in number of people forced the use of peat soil in borneo to be used as an alternative for their settlement. But the natural form of peat soil itself has become a challenge to the construction, therefore needs to be reinforced, one of the method is stabilisation. The optimum composition of lime and rice husk ash used for stabilization is 15% from the peat soil wet unit weight for the peat that got influence by surrounding water.Because of the few things above, the research in kacapuri foundation above the stabilized peat soil is established. From the test conclude that the value of GS rise to 1,584, water content lowered to 221,393 % and the unit weight is rise 1,158 t/m3. Pore value lowered to 3,386 and pH rise to 5,2.From the consolidation test the total settlements and vertical strain is concluded. The total settlements is lowered to 0,18 mm. The shear strength parameter is rise with the cohesion 0,1 and internal friction 30,646o. The ultimate bearing capacity qu for kacapuri foundation above the stabilized peat soil according to terzaghi formula is 87,675 t/m2.

Abstract

I cross-section of reinforced concrete reduce weight and concrete needs, but the reduction in strength is not too large. Based on observations I section reinforced concrete beam is quite complicated and takes much longer time for the manufacturing. Therefore another form of cross-section which is equivalent to weight reduction in I cross-section concrete beam, with hollow square cross-section of reinforced concrete beam. It is expected that hollow square cross-section of reinforced concrete has a same strength with I cross-section of reinforced concrete. So this research may provide an alternative lightweight concrete beam, efficient in materials, easy installation in the implementation of shear reinforcement, and easy in formwork manufacture. This research was conducted to identify and compare the behavior of the shear of hollow core reinforced concrete beam with an I cross-section beam that equivalent with its. This experiment is using four reinforced concrete beam length 2000 mm, a T beam with bottom flange as control beam (BK) with measurement: bfa = 600 mm, bw = 125 mm, bfb = 200 mm, h = 300 mm, tf = 100 mm and three hollow core T beam as test beam (BB1, BB2 and BB3) with measurement: bf = 600 mm, bw = 200 mm, blubang = 75 mm h = 300 mm, tf = 100 mm. This experiment is testing the static and dynamic. Static loading is performed with a four-point system load, static loads are given by the hydraulic jack. Observations on the static load carried on the first crack and at each initial crack addition until the ultimate fracture. With the parameters used is the amount of deflection, the strain of reinforcing steel and concrete, the crack pattern that has happened.From the results of the experiments can be concluded that the hollow core reinforced concrete beam can be used as an alternative to I section reinforced concrete beam. It is seen from the difference in the shear load capacity is not much different between control beam (BK) and hollow beam (BB), with the difference between BK (299.3 kN) and BB1 (337.6 kN) is 12.79%, with BB2 (350, 6 kN) or 17.14% and with BB3 (289.4 kN) or -3.31%.

Abstract

Indonesia merupakan salah satu negara dengan pembangunan infrastruktur yang sangat pesat. Pembangunan sektor jalan merupakan  salah satu pembangunan yang sedang masif dilakukan, terutama pada jalan dengan perkerasan kaku. Perkerasan kaku khususnya paving block banyak digunakan pada tempat khusus yang memerlukan kekuatan lebih untuk menahan beban sekunder. Pengaplikasian paving block pada pembangunan ruas jalan sudah seringkali kita jumpai pada banyak daerah di Indonesia. Penggunaan paving block  juga dinilai lebih ekonomis, efektif dan efisien daripada penggunaan perkerasan beton bertulang, paving block  juga memiliki tingkat kemudahan dalam pemasangannya. UMKM (Usaha Mikro Kecil dan Menengah) penyedia paving block di Banjarbaru hanya mengetahui bahwa pembuatan paving menggunakan semen dan pasir saja, mereka belum mengetahui bahwa paving juga dapat digunakan material limbah. Dalam hal ini Tim Pengabdian kepada Masyarakat Fakultas Teknik mengusulkan penggunaan limbah abu batu sebagai material pengganti pasir dalam pembuatan green paving block. Bimbingan teknis yang dilakukan termasuk penjelasan terkait prosedur pembuatan paving block berdasarkan SNI 03-0691-1996, metode curing atau perawatan, dan metode pengujian paving block. Berdasarkan hasil kuisioner terhadap peserta bimbingan teknis diketahui rata-rata 14,33% menyatakan sangat jelas, 33,33% menyatakan jelas, 47,67% menyatakan cukup jelas, dan 4,67% menyatakan kurang jelas.
