Abstract

Shear walls in a dual system are one of the structural systems to carry most of the lateral load with a maximum percentage of 75%, because geometrically this shear wall structure has greater rigidity so that it will be effective in providing a restraining influence during an earthquake on the building structure. The shear wall used in this building is a rectangular shear wall that is used to support the building structure and to increase the stiffness and stability of the structure against lateral loads. This Office and Warehouse Building has a total height of 16,5 m consisting of 4 floors. The modelling of this building uses ETABS V.17 software with the dimensions of column K1 500 x 500 mm, K2 300 x 300 mm, tie beam S1 300 x 500 mm, S2 300 x 400 mm, beam B1 300 x 500 mm, B2 300 x 400 mm, floor plate 150 mm thick and shear wall 300 mm thick with a span of 3 m. The structure of this building uses reinforced concrete with a concrete quality of 25 Mpa and uses screw reinforcement with a reinforcement quality of fy 420 Mpa. Based on the analysis, the largest inter-floor deviation value for the X direction on the roof slab is 44,3245 mm, while for the Y direction on the 4th floor it is 43,4885 mm. Based on the dual system control requirements, this planning has met the requirements because the percentage of shear walls obtained for the X direction is 72.817% and the Y direction is 74.59%.

Abstract

Bali is one of the provinces that are destinations for foreign and domestic tourists. This causes Bali to follow developments in several sectors, one of which is the construction sector. Of course, every building in Bali must guarantee its safety and comfort. Especially in infrastructure buildings, the security of which must be guaranteed because it involves the safety of many people inside. For example, hospital buildings included in risk category IV need to pay attention to their deviations. For example, in the Udayana University oral dental hospital building which was previously planned using SRPMK, the design deviation value met the requirements or did not exceed the permit deviation. This oral dental hospital building will be re-planned using a dual system. So these two structural systems are chosen for comparison regarding the deviation values ​​between the two to provide information regarding which structural system is more optimal. In this writing, the analysis shows that the deviation value produced by the dual system is smaller than the special moment resisting frame system. Namely, with a maximum value of the double system of 8.96 mm and SRPMK with a maximum value of 21.696 mm with a clearance of 30.77 mm on the 2nd floor in the x direction and in the Y direction the maximum value of the double system is 12.60mm and SRPMK with the The maximum value is 20.07 mm with a permit of 26.92 mm on the 3rd floor.

Abstract

When planning a tall building structure, the deviation due to lateral forces is very important to be taken into account in the planning of tall building structures. To reduce the amount of deviation in the structure adding by special structural elements, as shear walls. With the shear wall, can increase the stiffness of the building structure and absorb large shear forces along with higher the building structure and lateral force on structure will not fully accepted by frame structure which will result a decrease in deviation. Guestwing 1 The Ritz Carlton Hottel located in South Kuta District, Badung Regency, Bali. This building has a height of 20.2 m consisting of 6 floors. Planning with 2 models: a) SRPMK Existing Modeling, b) Dual System Model. Material specifications and loading are the same, just different in addition of shear walls and reducing the dimensions the building. Based on the results the analysis of the two models, the largest inter-storey deviation value in the existing model X=52.014mm; Y=47.960mm and for the dual system model X=25.614mm; Y=26.026mm. From the results of deviation analysis on both models, can be concluded that with addition of shear walls, there is a decrease in deviation 63.27% in X direction and 68.18% in Y direction. The most significant decrease occurs in dimensions and reinforcement of column K1 from size 350x800mm with 22 D22 reinforcement to column 300x600mm with 18 D22 reinforcement, beam B3 250x450mm for support area 17 D13 and field area 10 D13 to beam 250x400mm with the number of support reinforcement 11 D13, and the number of field reinforcement 7 D13. From the results of this planning can be used as a consideration for the construction of the next building for the use of shear walls in the structure.

Abstract

According to Central Bureau of Statistics (Badan Pusat Statistik), in 2015 the population of Special Capital Region of Jakarta was 10,177,900 people with the rate of growth 1.02% per annum. Approximately, 14.7% of the population are students. In order to fulfil the demand of good quality education, the X school foundation develops and builds new schools continuously, especially in Jakarta and its suburbs. The planning of school development should be done well. One of the initial steps is to conduct a feasibility study. Conceptual cost estimation is important at this stage. There are some difficulties in estimating the cost at the conceptual stage, such as the lack of preliminary information about the project, lack of project cost data, incomplete data, et cetera. The purpose of this study is to create model using Artificial Neural Network. To determine the input variables, analysis factors were used. After that, the model was created by using Matlab software. This research was conducted by collecting 15 data of school building projects. The result of this study shows the best Artificial Neural Network model is network architecture 7-5-1 with backpropagation algorithm.

Abstract

PT. Darma Sarana Nusa Pratama established the drainage system for the Cendana Marq housing complex in Tangerang. This drainage system was built on previously agricultural land, which has undergone a change in function to residential use. Consequently, the infiltration capacity of rainwater on this land has altered, affecting the volume of runoff directed towards the drainage system. The objectives of this research include planning the drainagesystem for the Cendana Marq housing complex in Curug, Tangerang. This involves designing the drainage network, determining the amount of rainwater runoff, calculating the necessary dimensions for the drainage channels to accommodate the runoff, assessing the required capacity for a retention pond intended for temporary water storage, and identifying the necessary drainage facilities for the Cendana Marq housing system. The study employs a qualitative research methodology. The findings indicate that the dimensions of the tertiary channels range from 0.40 to 0.55 meters, secondary channels from 0.80 to 1.40 meters, and primary channels at 1.50 meters, all leading to a retention pond. The runoff volume generated by the housing development is calculated to be 1.45 m³/s, which will be temporarily held in the retention pond within the residential area. To enable gravity flow, the required embankment height for the Cendana Marq housing complex is 2.10 meters (+7.302) above the village road (+5.402). Prior to the establishment of the housing complex, the river did not overflow during rainfall, with water levels matching the height of the embankment. The inflow to the Afvoer Cantel from the watershed area before the housing development was 0.28 m³/s. The planned drainage system for the Cendana Marq housing complex will manage rainwater runoff through the retention pond and designated channels, allowing for gravity drainage. Thus, the CendanaMarq housing complex in Tangerang is not expected to adversely impact the capacity of the system.

Abstract

River borders are natural areas that need to maintain their primary function but currently tend to change into artificial areas, which are used for human activities and building construction. Limited urban land and economic factors are likely the causes of people building in river border areas. This study aims to analyze the function of buildings that are not by the use of space on river borders so that they can be used as a reference for controlling spatial planning. Building and river data are needed to assess the level of consistency and inconsistency of buildings in river border areas. The level of inconsistency is calculated based on the number of buildings located in the river border area divided by the number of buildings outside the river border. The results of the building consistency index analysis of 0.87 indicate that the majority of buildings in Padang City tend to be outside the river border area. However, there are still many buildings that are inconsistent with land use regulations, namely those located in river border areas. The Sungai Pisang watershed is recorded as the most erratic, even though it has the fewest buildings. On the other hand, although the Batang Arau watershed has the largest number of buildings, it shows a lower inconsistency value than the Sungai Pisang watershed and Air Timbulun watershed.

Abstract

ABSTRACT The Failure of reinforced concrte beam structures can occur due to the function of tensile reinforcement, compression reinforcement, and stirrups not functioning properly so that the beam is unable to withstand/ support the working load. This study aims to analyze the strength of reinforced concrete beams using inclined stirrups at an angle of 135° with a variation of 100 mm and 150 mm. Reinforced concrete is chosen as a combination of concrete and steel to increase the tensile strength that concrete does not have. The Ultimate Stress Design (USD) method is used to design reinforced concrete element structures. The test involved two samples of reinforced concrete beams measuring 15x15x80 cm. Based on the test, the average compressive strength of 100 mm concrete beams was 28 MPa and 150 mm was 29 MPa. The tensile test of D-13 threaded steel reinforcement produced an fy of 354 MPa and D-8 plain fy value of 369 MPa. The flexural strength of concrete beams at stirrup distances of 100 mm and 150 mm was recorded at 23.67 Mpa with a maximum deflection occurring in beam B-1 of 46.4 mm and a maximum deflection in beam B-2 of 47 mm. The results of this study provide important information about the effect of variations in inclined stirrups on the structural performance of reinforced concrete in increasing the flexural and shear strengths that occur in beams. Keywords: Reinforced Concrete, Diagonal Stirrup Reinforcement, Compressive Strength, Ultimate Stress Design (USD), Ultimate Moment Capacity, Tensile Test, Bending Strength.
