Abstract

Concrete is a common construction material whose quality depends on parameters such as compressive strength and split tensile strength. To reduce the environmental impact of river sand use, this study evaluates the use of sea sand as a partial replacement for fine Aggregate. Although sea sand contains salt, special treatment can reduce its salt content and is expected to improve the quality of high-grade concrete. The objectives of this study were to assess the impact of sea sand on the mechanical strength of concrete and to determine the optimum percentage of sea sand in high-quality concrete mixtures. This study used compressive strength, split tensile strength, and shear strength testing methods with variations in sea sand content in concrete mixtures of 0%, 25%, 50%, and 100%. The tests were conducted using a Compression Testing Machine (CTM). The results showed that using sea sand reduced the mechanical strength of concrete. Compressive strength decreased from 43.09 MPa to 29.91 MPa, splitting tensile strength decreased from 4.23 MPa to 1.21 MPa, and shear strength decreased from 10.23 MPa to 5.97 MPa with an increase in the percentage of sea sand. Therefore, it can be concluded that although sea sand can be used, its use in large quantities reduces the mechanical strength of concrete. The optimum percentage must be adjusted to balance sustainability and structural strength.

Abstract

Lombok Island is one of the earthquake-prone areas, located between two earthquake generators. Based on these conditions, it is expected that construction in earthquake-prone areas can meet the standards. Shear walls are one of the earthquake-resistant structural systems used to resist lateral forces. Three alternative shear wall shapes will be analyzed using the numerical method: the L, I, and T shapes. The types of loads to be analyzed are dead loads, live loads, and earthquakes. Drawing from the findings of the conducted analysis, it is discovered that the most effective shear wall position in resisting lateral forces is the shear wall located at the corner of the building, based on the values of the drift that occur in the x and y directions. In addition, increasing the number of shear walls can reduce the internal forces that structural components experience. The optimum drift value is obtained from alternative 1, the L-shaped shear wall (elbow), with a drift value of 0.000495 mm in the x direction and 0.000883 in the y direction.

Abstract

A foundation is a structural element that transfers building loads to the soil layer, thereby ensuring the stability of the construction. The foot plate foundation is a type of shallow foundation commonly used for low- to medium-rise buildings. This study aims to analyze the bearing capacity of foot plate foundations using the Terzaghi and Meyerhof methods and to compare the calculation results from both methods within the context of the construction of the Drug Rehabilitation Building at Mutiara Sukma Psychiatric Hospital, Mataram City. The study employs a quantitative method with a comparative analysis approach. The data utilized consists of secondary data from Cone Penetration Tests (CPT/sondir) and foundation design drawings. The Meyerhof and Terzaghi methods yielded different bearing capacity values at each testing point; these differences are attributable to the specific equations, soil parameters, and correction factors employed. This study could not determine the most representative method, as no validation was performed using load tests or actual settlement data. Regarding the allowable bearing capacity of the shallow foundations, the highest values were obtained using the Terzaghi method: 15,749.5 kN at point 1 (compared to 12,879.92 kN via Meyerhof). At point S2, the values were 3,180.57 kN (Terzaghi) and 2,202.51 kN (Meyerhof); at point S3, they were 6,580.49 kN (Terzaghi) and 5,582.46 kN (Meyerhof); and finally, at point S4, the values were 6,580.49 kN (Terzaghi) and 5,063.29 kN (Meyerhof).
