Abstract

Test the load to collapse needed to test the reliability of the structure , ie by knowing the maximum load that can be borne by the structure. The process of bending and deflection of reinforced concrete beams is also necessary for students to understand the world of construction and reinforcement due to shear or bending , through experimental studies and numerical studies. Whereas laboratory tests conducted on relatively more expensive. One solution to the numerical methods are finite element methode. The main purpose of this research is to create a simulation of bending, deflection, maximum load and cracking for reinforced concrete beam with orthotropic models. So the simulation of bending, deflection, maximum load and cracks can be represented with this program without always perform laboratory testing. Program performance is analyzed based on laboratory test results and literature. The pattern of cracked beam bending shear formed shows the influence of concentrated loads are in the area moment of pure, cracks formed experiencing slope indicating still have a shear work but further away from the location of concentrated load slope becomes increasingly erect indicating less influence concentrated load , While near the pedestal cracks experiencing tilt direction marks in those areas experiencing the combined effects of shear stress and maximum normal stresses are close to zero and the impact of support reaction. The pattern of cracked beam bending pure looks toward the crack perpendicular to the horizontal axis beam this is due to the absence of shear stress working along the span structure, in the absence of shear strain, the strain off the main drag parallel to the horizontal axis and direction cracked up to be perpendicular direction tensile strain, this corresponds to the existing reference.Kata kunci : finite element, reinforced concrete beams, crack pattern.

Abstract

The research is do to analize the compressive strength and water absorption in the CLC lightweight brick made with a mix of fly ash and the ashes of andesit sawed stones and also to know if waste fly ash and the ashes of andesit sawed stones can be used as mixure of CLC lightweight bricks. The method used in this research that is by making light brick CLC with replacing sand material to the ashes of andesit sawed stones and fly ash substitution of 5%, 7%, 10%, 15%, 17% and 20% of the weight of the whole material. Lightweight brick that has been curing for 7, 14 and 28 days and then tested to obtain the compressive strength and water absorption from lightweight brick. Results of the research showed the largest compressive strength of CLC lightweight brick at the age of 7 days is 6 kg/cm2 on the rate of fly ash 20%. At the age of 14 days, the largest compressive strength value of CLC is 12 kg/cm2 on the rate of fly ash 20%, at the age of 28 days, the largest compressive strength value of CLC is 19.5 kg/cm2 on he rate of fly ash 20%. Water absorption of CLC lightweight brick on average at the age of 14 days is 18.54 gr/dm2/min, average water absorption of CLC lightweight brick at the age of 28 days is 12.44 gr/dm2/min, still enter into terms that reco mended with a maximum of 20 gr/dm2/min.

Abstract

Light concrete is one of concrete type which more and more applied during now. In Europe and United States light concrete have been long enough and many utilized. Compressive strength yielded by lower light concrete than compressive strengths yielded by ordinary concrete. But, weakness found on light concrete can be overcome with excess obtained that is lighter wight. Causing enables once for high rise building sewer structures of height. In this research, more pointly weighs against at light concrete with aggregate pumice with addition of paddy chaff ash. Aggregate applied with light material that is pumice and addition of paddy chaff ash to increase compress and exploits raffle around rural public. Paddy chaff ash is material having property as puzzolan. Weakness of light concrete having compressive strength lower than ordinary concrete tried improved with addition of usage of paddy chaff ash having property pozolan. Concrete pumice with comparison ( 1 : 2 : 2) with addition of chaff ash, optimum condition reached at chaff ash content 10% , this still possibly increasing but its the increasing of on the wane.

Abstract

Value engineering (rekayasa nilai) menurut Chandra (1986) adalah suatu usaha yang terorganisir untuk menganalisis suatu permasalahan yang bertujuan untuk mencapai fungsi-fungsi yang dikehendaki dengan biaya total dan hasil akhir yang optimal. Value engineering dipengaruhi beberapa aspek, diantaranya dilihat dari segi bahan, cara pengerjaan, jumlah tenaga kerja, waktu pelaksanaan, dan lain-lain. Hal ini bertujuan untuk mengoptimalisasi dengan cara pengefisienan anggaran biaya kembali agar mendapatkan anggaran yang paling hemat. Sehingga dari hal tersebut penulis melaksanakan value engineering pada Proyek Rumah Sakit Onkologi Kotabaru Yogyakarta. Kondisi proyek sekerang ini pada pekerjaan struktur bawah, kondisi perencanaan sebelumnya gedung di rencakan 3 lantai tetapi pada pekerjaan konstruksinya hanya 2 lantai. Atas alasan kekurangan ruang pada perjalanan konstruksi pemilik meminta untuk konstruksi menjadi 3 lantai. Dari kondisi tersebut penulis melaksanakan value engineering untuk mengoptimalkan desain struktur agar mendapat alternatif paling hemat. Value engineering pada proyek ini menggunakan metode zero-one dengan 2 alternatif pilihan yaitu merubah desain kolom,balok dan tetap menggunakan desain plat eksisting sebagai alternatif 1 dan merubah desain kolom,balok dan merubah material menjadi alternatif 2. Dari itu di dapatkan Penghematan untuk alternatif 1 Rp. 131.675.000-, dan untuk alternatif 2 Rp. 267.053.000-,Pada perhitungan dengan metode zero-one alternatif terbaik yaitu alternatif 2 dengan bobot 55,55% dan bobot alternatif 1 adalah 44,45%.

Abstract

The installation of clean water is a very important building component to supportthe activities of residents in the building, because this component is a provider ofwater needs for building occupants to carry out bathing, washing, cooking activities,and so on. In planning a clean water installation system, four criteria must be met,namely: Sufficient quantity, Hygienic, Optimal technical, and Economical. Researchhas been carried out by modeling clean water installation to determine the type ofpipe that most effectively meets the clean water installation criteria to be applied toresidential buildings. The method used in this study is the modeling of a clean waterpipe installation with 3 types of pipes (Polyvinyl Chloride (PVC), Poly PropyleneRandom (PPR), and Galvanis), measuring the flow rate and water pressure bysimulating all the open sanitation points and simulating one of the open sanitationpoints in turn, then performing calculation of Implementation of Budget Plan forpipe installation. The results showed that the flow rate and pressure readings on thePVC pipe installation experienced an increase in the flow rate of 0.00624 m3 andthe pressure decreased by 3.015 psi, the PPR pipe installation experienced anincrease in the flow rate of 0.0104 m3 and the pressure decreased by 3.86 psi, whilethe galvanized pipe installation experienced an increase in the flow rate of 0.029 m3and the pressure decreased by 3,285 psi. The cost needed to make a PVC pipeinstallation is Rp. 336,635, to make a PPR pipe installation of Rp. 514,583, and toinstall a Galvanized pipe of Rp. 538,370. Based on the results of testing and analysisof the implementation budget, it can be concluded that the most effective type of pipeto be used in the installation of clean water pipes in residential homes is PVC pipe.
