Abstract

The column interaction diagram is a boundary area graph showing the various combinations of axial loads and moments that the column can safely hold. The benefit of a column interaction diagram provides an overview of the strength of the column in question. This study aims to analyze rectangular and circular columns using column interaction diagrams and then compare the strength of the columns in withstanding a combination of axial loads and bending moments with the same area. In this study, square and circular columns have the same number of reinforcement, diameter of reinforcement, steel strength, concrete quality, and cross-sectional area. The column is reviewed based on five conditions, namely pure axial load conditions, pure bending moment, and three failure conditions. Based on the five conditions that occurred, a column interaction diagram was created by using Microsoft Excel. Results of the analysis show that in the same area, the square column is stronger in withstanding the bending moment (Mu) of the circular column by 0.015 - 0.61%, while the circular column is stronger in resisting the axial force (Pu) of the square column by 1,9 - 4.4%.

Abstract

Along with the increasing pace of development, many methods and research have been carried out and developed aimed at increasing the strength of concrete, one of which is by utilizing waste rice snail shells as a partial replacement of cement. This snail is considered a pest for farmers. Snail carcasses can also damage the environment and cause a bad smell. This can be used and utilized as an alternative material in concrete mixtures. The percentage of use of rice snail shell substitution varied, namely 0%, 10%, and 15%. The tests carried out were the compressive strength test, split tensile strength test, flexural strength test, and the modulus of elasticity of concrete with a concrete quality of 25 MPa. The test objects used were cylinders measuring 15 cm and 30 cm high and beams measuring 60 cm × 15 cm × 15 cm with variations in age of 7 days, 21 days, and 28 days. The highest value was obtained at 10% snail shell variation with 27,540 MPa, 2,735 MPa, 4,131 MPa, respectively. so that the 10% snail shell variation used in this study is still safe to use as a cement substitution material in normal concrete mixtures.

Abstract

The problem of the quality of the asphalt mixture, especially on the surface layer, is a matter that really needs to be considered because a poor asphalt mixture will cause the surface layer on the road to be damaged quickly or not in accordance with the expected service period. This research was conducted to test the AC-WC mixture with added waste tires. The research methodology uses the Conventional Marshall method to obtain the characteristics of the AC-WC mixture and Marshall Immersion to obtain the Marshall Residual Stability value. The results show that the characteristics of the AC-WC mixture meet the 2018 Highways Specifications. The results of the Marshall Immersion test with an optimum 4% used tire content obtained a Marshall Stability value of 94.64% and the effect of adding used tire rubber will make the cavities in the mixture smaller thus the mixture can be resistant to water.

Abstract

One model of structural planning that can be used to make the building structure efficient is to add the secondary beams. Based on these assumptions, this paper is made to analyze the effect of placing secondary beams on the floor structure of the building to determine the efficiency that occurs to the thickness of the slab and the reinforced concrete material used. In the case of planning the Toko Satu Sama building on Jl. Perintis Kemerdekaan City Makassar floor plan is given one secondary beam on the x-direction and produces a plate thickness of 150 mm. The floor plan is re-planned by making a floor plan without secondary beams, a floor plan with y-directional secondary beams and a floor plan with x-and-y secondary beams. The bending moment that occurs on the floor plate is calculated using the 1971 PBI method, but still considering the latest provisions in SNI 2847, 2019. The results of the calculation showed that the floor plan with the pattern of placement of secondary beams in the direction of x and y (h = 120 mm) can streamline the plate by 20% of the thickness of the plate with the pattern of placement of the secondary beam in the direction of x. In line with that, concrete needs can be effective by 15,359 % (12,284 m3). Even if it has more reinforcement needs, the pattern of placement of secondary beams in the direction of x and y is the most efficient pattern.English translation.

Abstract

This study explains the use of solution variations in the concrete soaking process, knowing the increase in concrete soaked in variations of concrete soaking solutions. As well as knowing the decrease in the strength of concrete due to combustion at high temperatures. This study aims to determine the improvement of concrete quality in the form of mechanical properties, namely compressive strength, split tensile strength, and bending strength. The collection of aggregate material was carried out in Pucak River, Maros Regency, South Sulawesi. The variations of the immersion solution used are Seawater, Hydrochloric acid (HCL), Sodium Hydroxide (NaOh). While the variation in the duration of burning concrete is 0 hours and 3 hours. This study showed that the results of concrete compressive strength in soaking variations experienced the highest percentage increase in normal water immersion, namely 17.728% while the lowest occurred in hydrochloric acid soaking of 0.652%. Then after 3 hours of combustion with a temperature of 3650 C the highest percentage decrease occurred in the immersion of hydrochloric acid by 27.678%. Test results decreased tensile strength the highest split in hydrochloric acid immersion by 38.824%, 3, the lowest in normal water immersion by 30.275%. The results of the Bending Strength Test experienced the highest decrease in hydrochloric acid immersion by 26.316%, the lowest in normal water immersion by 21.154%. The use of solution variations in concrete soaking still meets the compressive strength of the plan whereas in burning concrete for 3 hours resulting in a decrease in the strength of the concrete which indicates the concrete is not viable in function.
