Abstract

The development of coronavirus or Covid-19 in Central Kalimantan is currently increasingly worrying. All areas in this province are now in red zone status. This transmission is very fast spreading, so we are doing outreach to the community at Budi Mulya Orphanage, Palangka Raya City, implementing 6 recommended handwashing steps to kill the Covid 19 virus that sticks to our fingers. Washing hands with soap is one of the sanitation measures to prevent disease. Even WHO also recommends 6 steps in washing the palms of hands, the palms of backs of hands, between the fingers, the backs of hands, the thumbs, and the tips of fingers. The last method of washing hands is to clean soap with running water and dry it. To support the 6-step handwashing program, we are working with the orphanage's leadership to make a table for a water storage basin used for washing hands. The table is made permanent, made of reinforced concrete, whose composition of the reinforced concrete mixture is mixed with processed rattan waste that is no longer used as a substitute for concrete fiber. The rattan waste mixture used was 0.25% of the total volume of concrete.

Abstract

The column is a critical element in the building structure, the failure of the column will directly result in the collapse of other related structural components. The column must have strength, stability and ductility. In increasing the capacity and ductility of the column by providing confinement, to protect concrete elements from breaking due to the influence of the working pressure. Analyzing ultimate axial load capability, stress-strain distribution patterns and crack patterns in concrete elements and column ductility. Tests of several models and variations of the restraint distance in short columns of normal concrete quality with longitudinal reinforcement of steel steels and carbon steel transversal reinforcement. The columns were analyzed using the Finite Element Analysis (FEA) method with the help of a full scale ANSYS 3-D application, with material properties for concrete using SOLID65 and steel reinforcement using LINK8 and SOLID45 loading plates. The type of pedestal used is the joints with axial loading (axial loadstep) centric direction. The effect of the restraint model and the variation of the restraint distance to the value of the column ultimate axial load for the whole model is relatively small with a ratio of 1.079, while for the ratio of the axial deformation ratio of 1.496. The pattern of stress and strain distribution when yielding spreads throughout the column area but when it reaches the ultimate distribution the concentration is concentrated in the support area. The first dominant crack occurs in the pedestal area and generally occurs in the concrete blanket layer, in the ultimate condition cracks have occurred evenly throughout the column area. The ratio of the ratio of ductility values ​​for all column models and the restraint distance is relatively large with a ratio value of 1.523

Abstract

Structural design is an important element in a building to produce a strong, safe, and economic structure. The structure is designed according to the needs of the working load. The earthquake area will produce different dimensions of the structure and reinforcement with non-earthquake. This study aims to compare the need for dimensions and reinforcement in earthquake vs non-earthquake areas. The design standard refers to SNI 1727:2013, SNI 2847:2013, SNI 2847-2019, and SNI 1726-2019. The building being studied is a Type 36 MBR Prototype Flat (3 floors) using Fc 25 MPa concrete and Fy 400 MPa reinforcing steel. Research on the upper structure of Columns, Beams, Ring balks, and Floor plates, includes the design of the structural dimensions and reinforcement requirements. The structure's dimensions and the reinforcement area will be designed efficiently and declared safe by controlling the reinforcement ratio (ρ), Limitation of structural dimensions, Capacity Ratio (Pu/ϕ.Pn), and deflection. Analysis of the calculation of the structure using the computer application SAP 2000. The results of the study obtained a comparison of the structural dimensions of the earthquake vs non-earthquake load column with an average of 25.42%, while for the need for the main reinforcement area of 22.50%, the Capacity Ratio value (Pu/ϕ.Pn) between 0.535-0.967. The dimensions of the beam and floor slab structures with an average of 23.84%, while the area of flexural reinforcement (AS) is 20.22%, with a maximum deflection (δ) for all beams and floor slabs with values between 0.13 - 3.70 mm. Comparison for the entire structure the dimensions with an average of 24.63% while the reinforcement is 21.36%.

Abstract

Many structures in Central Kalimantan are built on soft soil and peat. One type of foundation that can be used for support is the Galam wooden foundation. To ensure stability, the required number of Galam wooden piles must be calculated based on the working load. The foundation"™s bearing capacity is determined through soil testing, such as the Cone Penetration Test (CPT), with the data analyzed using the Meyerhof method. Structural load calculations were performed using SAP2000 software, with the analysis modeled in 3D according to the SNI-1727-2013 loading standard. This study aims to determine the structural load applied to the foundation, the bearing capacity needed for the Galam wooden foundation to support this load, and the required number of wooden piles. The results show that the average foundation load is 11.27 tons for single-story structures, 26.42 tons for two-story structures, and 67.21 tons for three-story structures. A single Galam wooden pile installed at a depth of 0"“8 meters can support a load of 0.82 tons for single-story structures, 1.28 tons for two-story structures, and 2.02 tons for three-story structures. The average number of Galam wooden piles required for group pile foundations is 22 piles for single-story structures, with a load-to-bearing capacity ratio (Pu/Pn) of 0.69; 32 piles for two-story structures, with a ratio of 0.79; and 45 piles for three-story structures, with a ratio of 0.65.
