Abstract

In some building designs that carry a high aesthetic or architectural value, the use of flat columns brings a number of significant advantages. Their slender design provides more flexibility in interior layout and adds to the aesthetic value of the building. This study was conducted to determine the reinforcement requirements and behavior of flat columns as well as checking the displacement in accordance with SNI 1726:2019. The results show that column I and column L are categorized as swaying and long columns, while column T and column Plus are included in the category of non-swaying and short columns. The required reinforcement requirements are as follows: For column I with dimension 130 x 800, 10D16 main reinforcement is required with D10-100 mm stirrups inside the plastic joint area and D10-150 mm outside the plastic joint area. Column L of dimension 130 x 500 requires 16D16 main reinforcement with D10-100 mm stirrups both inside and outside the plastic joint area. T columns of dimension 130 x 500 require 10D16 main reinforcement with D10-100 mm stirrups inside and outside the plastic joint area. Plus columns of dimension 130 x 400 require 12D16 main reinforcement with D10-100 mm stirrups inside and outside the plastic joint area. The maximum defelction that occurs is still within the permissible tolerance limits of 15.32 mm in the X direction and 11.15 mm in the Y direction so that the building structure is declared safe and stable against the loads received in accordance with SNI 1726: 2019.

Abstract

Efficiency in structural design is important to optimize the use of materials and costs, while maintaining strength and stability to ensure the safety of the building. With construction design regulations constantly updated, careful and precise planning calculations are crucial. This study identifies overdesign in columns, beams, and foundations of existing buildings, and aims to determine more optimal and efficient dimensions and repetitions, resulting in stronger, more economical, and standard-compliant buildings. The research was conducted in a 4-storey office building with dimensions of 32 x 15,725 meters will be analyzed based on SNI 2847:2019, SNI 1726:2019, and SNI 1727:2020. The analysis was carried out using Microsoft Excel and ETABS. The results of the study showed that there was overdesign in the main column, main beam, and foundation. On a beam of 400mm x 650mm it produces an efficiency of 17.46%. The bending reinforcement requirement results in an efficiency of 21.785%. Meanwhile, the shear reinforcement and middle reinforcement are the same as the initial planning. In a 450mm x 700mm column it produces an efficiency of 16%. For shear reinforcement, an efficiency of 10% is obtained. As for the bending reinforcement, it is the same as the initial planning. In the foundation design, 4 square piles with dimensions of 450mm x 450mm and pilecap dimensions of 2600mm x 2600mm x 500mm with reinforcement requirements for the x direction D22-100 and the y direction D22-125. Resulting in a pilecap volume efficiency of 28.888%.

Abstract

The increase in development growth throughout the world every year is directly proportional to the increase in demand for construction materials. To overcome the very limited sources of natural materials, alternative materials are needed as substitutes for construction materials. Utilizing nickel slag waste as an alternative material to replace natural aggregate to reduce the extraction of excess natural aggregate and preserve limited natural resources. The purpose of this study was to determine the Marshall characteristics and ideal composition for using nickel slag as a substitute for aggregate in worn-coated asphalt concrete (AC-WC) mixtures. The test specimens used were a mixture of worn coated asphalt concrete (AC-WC) with variations in nickel slag content, namely 0%, 10%, 40% and 70% and optimum asphalt content (KAO) respectively of 5.5%; 6%; 5.5%; and 5%. Based on the results of study that has been carried out, the optimum stability value was obtained at 1087.38 kg at a nickel slag content of 70% with an optimum asphalt content (KAO) of 5%. This value is greater than the stability value obtained at a nickel slag content of 0% with an asphalt content. optimum 5.5%, namely 1034.39 kg. From these results it can be concluded that nickel slag can improve the performance of worn coated asphalt concrete (AC-WC) mixtures and the ideal composition of nickel slag is at a nickel slag content of 70% with an optimum asphalt content (KAO) of 5%.

Abstract

Road construction planning must consider the characteristics and strength of the soil. This study aims to determine the classification of soil and the effect of fly ash-based geopolymer as an added material on the specific gravity of soil. Specific gravity testing was carried out using a pycnometer to obtain the specific gravity of the soil. The test object used is a soil sample added with geopolymer with fly ash as raw material and an alkaline activator (Na2SiO3and NaOH). The NaOH concentration is 10 M with a solution ratio of 2.0 (Na2SiO3 to NaOH), fly ash content of 20%, and variations in S / L (fly ash to activator) levels of 1/2 and 1/2.5. Based on the research that has been done, the results show that the soil used in the study is included in the organic clay soil with a specific gravity value of 2.49. The effect of fly ash-based geopolymer in this study increases the specific gravity value, with a specific gravity of 2.60 for variation B (80% soil, 20% FA, S/L 1/2) so that the soil falls into the organic clay category and 2.69 for variation C (80% soil, 20% FA, S/L 1/2.5) so that the soil falls into the non-organic clay category.

Abstract

A embankment dam is a dam built by stockpiling materials such as stones, gravel, sand, and soil on a certain composition with the function of carrying or lifting the water surface contained in the reservoir [1]. One of the structural safety of a embankment dam is against water seepage. Water seepage that occurs on the slope body during flooding can affect the decrease in slope stability, where the seepage will cause piping symptoms [2]. This study aims to determine the seepage discharge value that occurs in the dam body. The object of this study was Sindang Heula embankment dam in Banten Province. The method used is to conduct an analysis using GeoStudio software with the SEEP/W feature for seepage discharge. Simulation run in two scenarios as steady state condition and transient. Both scenario also run at least on three reservoir water level conditions. They are water level during flood, normal water level and half of full water level. Steady state condition gave seepage flux about 3.773×10-6 m3/sec/m2 as maximum value. In another hand, 30 days transient simulation gave maximum value about 8.7188×10-4 m3/sec/m2 and it occurred in small reference time after initial run. This study infomed that SEEP/W has capability to simulate water flux through porous media of embankment dam.

Abstract

Land is one of the important elements in construction projects and must have high bearing capacity to support the structure above it. Civil construction, whether roads, buildings, or other structures, will last a long time if one of the factors is supported by good subgrade. The location of the road in Sudimanik Village has soil that is classified as expansive clay, which has a high shrinkage capacity due to changes in water content. One way to improve unstable soil is to add additional materials such as Fly Ash and Ground Granulated Blast Furnace Slag (GGBFS).The purpose of this study was to determine the characteristics of the soil based on the classification and physical properties of the soil using the Unified Soil Classification System method and to determine the characteristics of the soil and the effect of adding consistent variations of fly ash at 20% and variations in the percentage of GGBFS 0%, 10%, 20%, and 30% as additional material for soil stabilization against the unconfined compressive strength value with variations in curing time of 0, 7, 14 and 28 days.The results of this study obtained soil classification according to the USCS classification including ML or inorganic silt and very fine sand, rock dust or fine silty or clayey sand. The plasticity index value after the study was 12.69%, in variation E, namely the addition of 20% fly ash and 30% GGBFS. The optimum qu value is in variation E with a curing time of 28 days, which is 2.287 kg / cm2. And experienced an increase in qu value of 295.918% from the original soil condition.

Abstract

C75 cold rolled steel is a material used in building construction with a lighter weight compared to conventional steel. One important aspect in the design of C75 light steel is the connection, where the connection must be designed safely so it is very important to maintain the structural integrity of the building and ensure the safety of building users. The aim of the research is to obtain the correct formulation for the C75 mild steel connection type in relation to the thickness of the C75 cold rolled steel. The method used is to create a connection system in the form of a variety of connections consisting of connections using screws only, combined screws and bolts, and connections using rivet nails. Overall, from the test results, it was found that the use of mild steel connections with a modified model between screws and bolts produced a greater value compared to using rivet connection tools alone or screws alone, this happened the same for every thickness of mild steel tested, both thickness 0, 65 mm, 0.75 mm or 1.00 mm. The greatest results were found in the connection of 4 screws and 1 bolt at a mild steel thickness of 1.00 to 100.00 N with a deflection of 2.58 mm. When compared with rivets, the increase reached 42.50%, while compared with screws, there was an increase of 20.00%. So rivet connections are brittle compared to screws and screw and bolt connections are a more ductile connection, so they can be recommended as connections in light steel. It's just that mild steel which has a greater thickness tends not to cause buckling compared to mild steel which is much thinner, where buckling is likely to occur in the mild steel material.

Abstract

In the implementation of construction projects, problems are often found, such as delays. One of the solutions is by accelerating. Acceleration is not only done to overcome delays, but can also be done if there is a special request from the owner. This study discusses the acceleration of time and cost using the crashing method in an apartment construction project in Bekasi City, which aims to determine the optimal time and cost of the three alternatives used. The work that is accelerated is some structural work that is on the critical path. Acceleration is carried out with three alternatives, namely the addition of working hours, the addition of labor, and the combination of additional working hours and additional labor. The results showed that with the alternative of adding working hours, the implementation time was 298 days at a cost of Rp. 140,751,032,332, obtaining a time efficiency of 5.7% and a cost efficiency of 0.42%. With the alternative of adding labor, the implementation time is 292 days at a cost of Rp. 140,092,976,595, 7.59% time efficiency and 0.89% cost efficiency are obtained. With the alternative of adding working hours and additional labor, the implementation time is 290 days at a cost of Rp. 139,912,527,724, 8.23% time efficiency and 1.02% cost efficiency are obtained. Then it can be concluded that the alternative with the most optimal time and cost is the combined alternative of adding working hours and adding labor.
