Abstract

Bearing capacity is an aspect that is considered and considered before determining the type of foundation to be used in a building. The Palm Oil Mill Development Project in Central Kalimantan Province has a sand type of subgrade with a dense consistency. The Planning Consultant plans the type of Spun Pile Foundation in Zone C of Kernel Warehouse and Bakil Warehouse Buildings. The method used in the calculation uses Data Analysis of the CPT Test (Soil Test) and Hand boring. In Zone C Test Soil Test used is Soil Test 4 (S4) and Soil Test 5 (S5), for Hand boring using Hand boring 2 (HB-2). Calculation Analysis Using the Meyerhof formula to get the ultimate bearing capacity, lateral and axial bearing capacity. Based on the Calculation Analysis, the Ultimate Mini Pile Foundation Bearing Capacity is 20x20 87.20 tons in the Soil Test 4 area and 101.18 tons in the Soil Test 5 area. For the 20cm diameter well foundation, the calculation results are 68.45 tons in the Soil Test 4 area and 79.42 tons in the Soil Test 5 area. The calculation of the lateral permit load is obtained in the Soil Test 4 area for Mini Pile 20x20 2.23 tons and the Well Foundation 2.23 does not meet the requirements because it is less than the permit workload working in Zone C, which is 2.72 tons. Soil Test 5’s calculation meets the requirements with higher yields than the load working in the area, namely for Mini Pile Foundations 20x20 3.12 tons and Wells Foundations 3.12 tons.

Abstract

The development of high-rise buildings in Indonesia is now increasingly diverse. The need for increasingly narrow land functions affects the shape of the building which tends to be irregular. Irregularity in the building requires structural planners to build buildings that are safe against earthquakes but also do not forget the aspect of user comfort. In this study, an analysis of the dynamics of earthquakes was carried out in buildings that have vertical geometric irregularities by varying the dimensions and reinforcement of the columns. The behavior of the building structure produces structural responses in the form of base shear, fundamental period, displacement and story drift. Analysis of earthquake using dynamic analysis of response spectrum based on SNI 1726 2019 with the help of ETABS software version 9.7.4. The results of this research indicate that the variation of column dimensions and column reinforcement in buildings with irregular vertical geometry reduces the stiffness of the building thereby reducing the forces in the structure, increasing the fundamental period, reducing the base shear force, increasing the displacement and the story drift.

Abstract

The purpose of this study was to determine the effect of the use of fly ash waste and glass powder on the compressive strength of concrete. 17.5% at the age of 3 days, 7 days, 14 days, and 28 days. for the specimens used measuring with a diameter of 10 cm and a height of 20 cm as many as 36 test samples by making variations of the day as many as 3 samples of the test object, After testing the compressive strength of concrete, the compressive strength of the characteristic concrete with the addition of 7% fly ash and glass powder 5%, the maximum compressive strength at the age of 7 days was 23.35 Mpa, the age of 14 days was 28.93 Mpa, and the age of 28 days was 33.85 Mpa. These results exceed the value of the compressive strength of normal concrete characteristics and indicate that fly ash and glass powder increase the compressive strength of concrete. There is a strong influence from the addition of fly ash and glass powder with variations in the addition and certain age of concrete
