Abstract

Abstract — Industrial waste products can be considered as renewable resources, one of them is a steel manufacturing, which produced dust waste contain sponge iron, scrap metal and other steel wastes that impacted to environment. This waste material was called Electric Arc Furnace Dust (EAFD). This study investigates the feasibility of using EAFD as a cement replacement compared to silica fume (SF) and fly ash (FA) in terms of Chemical composition, workability, setting time, compressive strength and rapid chloride permeability resistance. The results showed that workability of EAFD is almost similar to control even if percentage of EAFD was increased. It is not refer to FA more workable or SF less workable with increase percentage of replacement. Furthermore, the EAFD significantly affect the setting time, which 3% EAFD replacement bring to prolong final setting time to more than 24 hours, while the setting time of SF and FA did not significant affected along with the increase replacement percentage. In addition, the 3% EAFD is optimum replacement for compressive strength and it is equivalent replacement level to 5% SF and 15% FA. Finally, the EAFD enhance the resistance for rapid chloride permeability more than FA but less than SF.

Abstract

This paper presents the application of linear and non-linear time series modeling approaches for simulating and forecasting streamflow at three stations located in three different rivers namely Kurau River, Ara River and Krian River of Bukit Merah watershed of Malaysia. The performance of linear autoregressive integrated moving average (ARIMA) model and non-linear artificial neural networks (ANN) model in forecasting the monthly streamflow of Malaysian river basins has been evaluated based on mean absolute percentage error (MAPE), root mean squared error (RMSE) and coefficient of determination (R2). The results show that both ARIMA and ANN methods are suitable for streamflow forecasting. However, ANN is better than ARIMA in dealing with short-memory streamflow data. In addition, ANN method is more flexible to use against the inconsistent data.Keywords: time series, streamflow forecasting, ARIMA, ANN, Bukit Merah

Abstract

Keude Ranto Peureulak Bridge a bridge connecting Keude Ranto Panjang with Keude Geurobak village and other villages in Ranto Peureulak Sub-district, East Aceh District. Keude Ranto Peureulak Bridge is planned with a span length of 20.8 meters and width of 7 meters. The longitudinal axis planned for the bridge is the posttractive pretreat type concrete girder. The girder plan includes gelagar dimensioning, stress calculation, prestress loss, cross-sectional capacity, deflection control, and drawing. The quality of concrete used is fc = 40 Mpa, the tendon used is seven wire strand diameter ½ inch with 51 mm diameter tendon sheath. Tendon fpu voltage = 1860 Mpa, fy threaded steel reinforcement = 320 Mpa, plain steel reinforcement fy = 240 Mpa, and efficient cross-sectional height is 0.9 meters. From the calculation results obtained the moment that occurred on the girder of 2563,439 kNm on the calculation of the third combination. The number of tendons obtained from the calculation is 3 pieces with 7 pieces of strand on each tendon. Losing the total prestress force is 380,694 Mpa. The principal reference is used D13 mm, the shear reinforcement is used Ø10-100 mm at the support area and Ø10-600 mm in the field area. The ultimate moment capacity of the prestress beam is 5575.60 kNm from the calculation of the third combination. The largest deflection of 0.0247 meters due to a combination of two loads. All the results of the calculations obtained are safe to use.Keywords: girder, prestress, tendon, reinforcement, deflection

Abstract

The high-rise building structure is prone to lateral forces, mainly due to the force generated by the earthquake. In calculating the multilevel building structure there are 2 ways, namely with Open Frame and Open Frame combination with shear wall. The shear wall is a wall that acts as a stiffener and is also a core wall for rigging entire buildings designed to withstand shear forces, lateral forces caused by earthquakes. so that the horizontal deformation (deflection) becomes small. The analysis used in this research is spectrum response analysis based on SNI 1726: 2012. This research has 3 model of set back building which will be reviewed, that is the model of set back building with special moment frame system, the model of backyard building with shear wall of each side and model of set back building with shear wall only on one side. All load inputs, stiffness and structural dimensions are the same, which differ only the special moment frame system model and the sliding wall placement used. This building has a height of 39.5 meters (10 floors). Based on this data it shows that the deviation result with the deviation modeling for the model is 0.075 m for the X and 0.064 direction for the Y direction for model 2 0.051 m for the X and 0.050 m directions for the Y direction and for model 3 is 0.074 m for the X and 0.048 for direction Y.Keywords: Set Back, Irregular Building, Drift Story, Shear Shear, Shear Wall, Special Moment Resume Frame.

Abstract

Earthquakes are a natural phenomenon that can’t be circumvented by humans where the incident resulted in material losses and casualties. The impact was mostly occur by the damage and the collapse of a building. The technology developed in recent foundation is very influential to minimize the collapse of a structure due to the earthquake. Base Isolator is a breakthrough cutting edge technology that is placed on the foundation that serves to reduce the effects of earthquakes. Stiffness in the structure also affected the durability of building damage and collapse. The brick wall serves to increase the stiffness of a building structure. This final project aims to determine and compare the response of structures using technology base isolator and fixed base. The parameters are reviewed, namely natural period (T), the shear force (V), and deviation (δ). Analysis used is equivalent static analysis and response spectrum analysis. There are four models that became a point of comparison, the fixed base structure without a brick wall, fixed base with brick walls, base isolator without a brick wall, and base isolator with brick walls.Keywords: Earthquakes, Base Isolator, Stiffness, Technology Foundation, Brick Walls

Abstract

The meeting of three major tectonic plates makes Indonesia prone to earthquakes, be it the Indo-Australian plate, the Eurasian plate, and the Pacific plate. Earthquakes are caused by the release of energy generated by the pressure caused by moving plates. Its essence is not earthquake that damage building but anticipation of building which must be in earthquake resistant design. In this case, the building structure must be designed to be earthquake resistant. One of earthquake resistant building technology is technology with base isolator system. This study aims to determine the displacement analysis that occurs due to the effects of earthquake on the structure of the building. Both in the use of base isolator and without using base isolator. The design of this structure is done by analyzing the time dynamic history load in the SRPMK building (struktur rangka pemikul momen khusus). With 10 storey floor building, regular shape, in SRPMK building. The structural elements reviewed in analyzing the displacement of the building structure are in a column, either for fixed base building of SRPMK or for SRPMK building with base isolator. Data analysis is done by using SAP2000 computer software. The result of analysis shows that the maximum fixed column SRPMK structure building structure on the 3rd floor reaches 27.97 mm from the base of the SRPMK fixed base. While at the base of the isolator there is a displacement of 5.79 mm from the base of SRPMK base isolator. The result of analysis shows that the building of SRPMK base isolator compared with SRPMK building, the value of displacement of final floor level structure (floor 10) can be reduced to 15.85%. Application of base isolator in this case can be used as its function can reduce earthquake load.Keyword : base isolator, displacement, SRPMK; analysis of time history.
