Abstract

Reinforced concrete is commonly used in any infrastructures. In building, it can be applied for beam and column separately, but the joints between those elements in this type of structure might be vulnerable due to the strength compared to the element itselft. In this study, some parameters namely ductility, stiffness, and energy dissipation of beam-column connection in precast concrete will be examined using finite element method. Six samples in this experiment are made considering some variations such as connection type in interior and exterios condition, round-shaped and rectanguler-shaped of column, and T-shaped and rectanguler-shaped of beam. Static loads were given in the middle of the beam and column so that the crack pattern can be obtained. From this experiment, it will be known the best and suitable joints by observing those three parmeters.

Abstract

Jembatan kereta api merupakan salah satu prasarana transportasi penting dalam memenuhi kebutuhan manusia. Seiring dengan bertambahnya usia suatu struktur, maka jembatan kereta api juga akan mengalami penurunan kapasitas yang disebabkan oleh faktor internal maupun faktor eksternal. Melihat dari kegunaan jembatan kereta api yang sangat penting, maka dibutuhkan struktur yang kuat serta mampu menjamin keamanan dan keselamatan. Perkuatan merupakan salah satu usaha untuk mengembalikan kapasitas muat suatu struktur sehingga mampu menahan beban yang terjadi. Dalam penelitian ini jembatan kereta api rangka baja tipe warren mengalami penurunan mutu baja sebesar 30%. Analisis dan pemodelan struktur rangka baja menggunakan software SAP2000 V.20 yang kemudian dilakukan perkuatan dengan mengganti elemen-elemen lemah pada struktur rangka baja. Hasil penelitian menunjukan bahwa, nilai mode shapes maksimum setelah dilakukan perkuatan pada arah perpindahan sumbu global X ( UX ) memiliki nilai yang lebih besar 0,072% dari sebelum dilakukan perkuatan yaitu dari 0,825365 menjadi 0,825962. Nilai periode (T) juga mengalami peningkatan sebesar 1,603% dari 0,370023 detik menjadi 0,375957 detik. Lendutan pada tengah bentang jembatan sumbu lokal horizontal searah bidang XY ( U3 ) mengalami penurunan sebesar 32,85% dari 36,437377 mm menjadi 24,467447 mm. Pada evaluasi tegangan, terdapat 25 batang yang mengalami field capacity yang kemudian dilakukan perkuatan dengan mengganti 17 batang dengan memperbesar dimensi profil sehingga seluruh batang tidak mengalami field capacity. Nilai tahanan maksimum pada batang yang tidak aman setelah dilakukan perkuatan menjadi lebih kecil dari 25,324 ton menjadi 23,861 ton dengan kapasitas yang meningkat dari 12,612 ton menjadi 34,824 ton.The railway bridge is one of the important transportation infrastructures in meeting human needs. As a structured age, the railway bridge will also experience a decrease in capacity caused by internal and external factors. Seeing from the use of the railway bridges which is very important, it takes a strong structure and can guarantee security and safety. Reinforcement is an effort to restore the load capacity of a structure so that it can withstand the burden that occurs. In this study, the warren type steel frame railroad bridge experienced a 30% decline in steel quality. Analysis and modeling of steel frame structure using SAP2000 V.20 software which is then performed strengthening by replacing the weak elements in the steel frame structure. The results showed that the value of the maximum mode shapes after the reinforcement in the direction of global X-axis displacement (UX) has a greater value of 0.072% than before the reinforcement is from 0.825365 to 0.825962. Period value (T) also increased by 1.603% from 0.370023 seconds to 0.375957 seconds. Deflection in the middle of the horizontal local axis bridge spread in the direction of the XY (U3) plane decreased by 32.85% from 36.437377 mm to 24.467447 mm. In the stress evaluation, there is 25 frames that experience field capacity which is then strengthened by replacing 17 frames by enlarging the profile dimensions so that all the bars do not experience field capacity. The maximum resistance value on the unsafe stem after reinforcement is smaller than 25,324 tons to 23,861 tons with capacity increasing from 12,612 tons to 34,824 tons.

Abstract

The paving block is an alternative to the use of pavement layer that is safe, strong and easy to installation and maintenance. Pavement paving block also can be produced both mechanically and manually. The added fly ash was a waste material from coal combustion in the steam power plant furnace in the form of fine, round, pozzolanic and fibre-resistant. Alkali Resistant Glass Fibre (ARG) which is shaped like a rope 18-36 mm long was added into the paving block with mixed compositions 1 Pc:10 Ps that aims to strengthen the compressive strength and flexibility of the paving block. This research was used 15 samples with mixture variation of fly ash 19% and fiber 0,25%, 0,5%, 0,75% and 1%. Based on the results of laboratory analysis, paving block (1 Pc: 10 Ps) with the addition of fly ash 19% and ARG 0.6% yielding a maximum compressive strength of 18.35 MPa. The addition of fibres with fly ash mixture was also able to increase the compressive strength of the paving block.

Abstract

Pavement using paving blocks is the right choice because of its easy installation and maintenance. One form is a quadrilateral type that is widely used for environmental and pedestrian roads. With good road access being one of the improvements in vehicles so that waste tires also increase, solutions are needed to reduce the impact on the environment but are also expected to provide benefits for paving block roads, especially increasing adhesion between paving block constituent materials. Based on this background, it was a research idea with the aim of determining the effect of adding waste tire rubber powder on the wear resistance of paving blocks. Research method with strength testing on paving block samples with a size of 5 cm x 5 cm x 2 cm a total of 18 samples. The results showed the average strength value of paving blocks with a mixture of waste tire rubber of 1%, 2%, 3%, 4%, 5% of 0.134, 0.223.0235, 0.246 and 0.247 mm / minute, so that the addition of waste tire rubber powder showed a decrease in the wear rate of paving blocks.

Abstract

The volume of work and materials in construction is one of the important aspects that can affect the budget of a construction as well as the procurement of materials. Small mistakes and the lack of accuracy of an estimator and quantity surveyor can cause cost overruns in the budget of a construction so that a method is needed to minimize the human error. Building Information Modeling (BIM) is one method that can be used to accurately represent materials and construction volumes where modeling utilizes digital modeling to support the Virtual Design and Construction (VDC) process. Revit is a software that implements the BIM system. The advantages of Revit are that apart from having a variety of families and items to support 3D modelling, Revit can do material take-off up to a layer, making it possible to do quantity take off with materials that have many layers. Revit can also detect clash detection which can detect collisions between fields before construction begins, which is very helpful in the construction process.

Abstract

The need for housing is increasing along with the rate of population growth. Simple livable housing is an option for low-income communities in accordance with the regional minimum wage. In making investments to make housing requires a feasibility analysis so that it can assess in accordance with the company's financial capabilities so that the company does not experience losses and make profits after investing large enough funds. This study aims to analyze the feasibility of investing in the MPR 2 Type 31/60 m2 simple housing development project in the Semarang Regency area which is viewed from a financial perspective using the Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP), and Benefit Cost Ratio (BCR) methods. Based on the research that has been done, it can be concluded in terms of the feasibility of investing in the construction of subsidized houses type 31/60 in MPR 2 housing is feasible. This can be seen from the results of the analysis with the positive NPV method of Rp.127,933,335.12 > 1, the results of the analysis with the IRR method of 9.79% > 5% (MARR), the results of the analysis with the PP method, it shows that the period of return on investment occurs for 1 year 4 days, and the results of the analysis with the BCR method of 1.018 > 1.
