Abstract

The Mataram Mayor's Building, West Nusa Tenggara, consists of 3 floors with a total height of 14.25 m. All floors of the building use reinforced concrete structures, which make them vulnerable to lateral forces, especially those caused by earthquakes. Earthquakes risk causing building damage, therefore a special frame-bearing structure is needed to withstand earthquake forces to prevent structural failure, therefore shear walls are needed to withstand lateral forces. The placement and shape of shear walls affect the building's ability to withstand lateral forces. The problem of researchers in this study is how to compare the effectiveness of the four variations of shear walls when resisting lateral forces. So that researchers get the goal of knowing the value of floor deviations in the x and y directions and knowing the optimal placement location point in resisting lateral forces. In this study, a general type of data collection method is used, namely data collection carried out by collecting working drawings from project service providers. Based on the results of the analysis of the four existing models, it can be concluded that the placement of the shear wall position is more effective if placed at the right corner of the L-shaped building, if viewed from the results of the floor deviation values in the x and y directions. Where the overall floor deviation in the x direction of variation 1 is 1.12 mm, while the deviation in the y direction is 2.80 mm.

Abstract

Infrastructure development in coastal areas is a strategic challenge in regional planning and civil engineering, due to complex soil characteristics, high sedimentation rates, and the influence of the marine environment that can reduce structural performance, especially in bridge construction. Saturated sandy soil conditions commonly found in coastal areas require the selection of appropriate foundation types to be able to safely support structural loads. This study aims to compare the bearing capacity of pit foundations and pile foundations on coastal soils based on Standard Penetration Test (SPT) data. The research method used is quantitative analysis with a comparative approach using the Meyerhof (1976) and Terzaghi (1943) methods. Secondary data in the form of SPT test results were obtained from the Suspension Bridge construction project in Cemara Village, Lembar District, West Lombok Regency. Calculations include end bearing capacity, cover bearing capacity, ultimate bearing capacity, allowable bearing capacity, and group pile bearing capacity. The analysis results show that pile foundations have a greater group pile bearing capacity than pit foundations. Based on the Meyerhof method (1976), the bearing capacity of the pile foundation group is 20,707.43 kN and the well foundation is 4,161.63 kN. Meanwhile, based on the Terzaghi method (1943), the bearing capacity of the pile foundation is 9,183.07 kN and the well foundation is 3,241.08 kN. These results indicate that pile foundations are more recommended for use in coastal soil conditions with low bearing capacity.

Abstract

The acceleration of infrastructure development in Indonesia has increased the demand for concrete, yet the use of natural sand is often hindered by silt content exceeding the 5% standard limit. Excessive silt content inhibits the hydration process and significantly reduces concrete compressive strength. This study aims to analyze the effect of silt content variations in fine aggregates and the effectiveness of plasticizer additives on the compressive strength of concrete with a design strength of f'c = 20 MPa. The experimental research used silt content variations of 2.82%, 13.52%, 21.71%, and 30.81%. Testing included material analysis, slump tests, and compressive strength tests on 15x30 cm cylindrical specimens at 3 days, converted to 28-day estimates based on PBI 1971. The results indicated that increasing silt content caused a drastic decrease in slump values and compressive strength. At the highest silt content (30.81%) without additives, compressive strength decreased by 36.34% to only 12.73 MPa. However, adding Additon H.E at a dosage of 200 ml/sack consistently improved workability and restored concrete strength, with increases ranging from 26.47% to 35.83% compared to concrete without additives. In conclusion, plasticizer additives are proven effective as an engineering solution to optimize concrete performance even when using low-quality materials.

Abstract

Indonesia has a high level of earthquake risk due to the interaction of active tectonic plates. This condition requires structural building planning that strictly complies with earthquake-resistant design regulations. This study aims to analyze the structural response of buildings to earthquake loads using the equivalent lateral force method based on SNI 1726:2019. The research also aims to conduct simulation and static analysis of a two-story building structure using ETABS and SAP2000 software in order to compare the results of inter-story drift, base shear calculations, and structural responses to earthquake loads. The comparison of the two software programs is intended to help verify whether the outputs, such as inter-story drift and base shear, show consistent patterns.The research method was carried out through three-dimensional structural modeling using the same parameters in both ETABS and SAP2000. Earthquake loading was calculated using the equivalent lateral force method. The results show that both software programs produce similar earthquake force distribution patterns; however, there are differences in the values of inter-story drift and base shear. The maximum inter-story drift produced by SAP2000 was 0.018055 m, while the maximum drift produced by ETABS was 0.014685 m. This indicates that SAP2000 generated a larger inter-story drift value compared to ETABS, with a percentage difference of 0.86%. Meanwhile, for the base shear values, both software programs also showed differences, where SAP2000 produced a base shear of 1753.734 kN, while ETABS produced a base shear of 1841.7433 kN. In this case, ETABS generated a larger base shear value compared to SAP2000, with a percentage difference of 0.95%. These differences are influenced by numerical assumptions and analysis parameter settings in each application. In general, the analysis results are still within the tolerance limits permitted by the standards.
