Abstract

This study presents a simulation analysis of the non-linear behavior of retrofit concrete material due to uniaxial loads modeled in the form of cylinders measuring 150 mm in diameter and 200 mm in depth using the ABAQUS. Analysis of this auxiliary program includes cases of normal concrete retrofit, concrete with retrofit concrete with a composition of 1% steel fiber, and concrete with retrofit concrete composed of 2% steel fiber. From the results of the study conducted, it was shown that in modeling the properties of concrete damaged plasticity in ABAQUS, the use of accurate compressive behavior equations for concrete cases with normal concrete retrofit was core concrete and retrofit concrete using the Alfarah, et al equation. For the case of concrete with steel fiber composition retrofit, core concrete uses the Alfarah equation, and retrofit concrete uses Zhou Jiajia, et al. Whereas to model the tensile behavior accurately in the case of concrete with normal concrete retrofit using the Alfarah, et al equation. And the case of concrete with retrofit steel fiber compositions using the CEB-FIB equation and the Ali & Nehdi equation. The results of ABAQUS analysis of force vs. displacement show a graphical pattern close to the similarity of retrofit concrete column experimental results ECC1 error force ratio and displacement 14.86% and -10.60%, and ECC2 14.82% and 8.01). Based on the stress analysis shows that there is a gradual increase in core concrete where the peak of stress is found in the core area of the concrete core and in the retrofit area is divided into two regions, namely stressing on the center and pulling on a small part of upper and lower column retrofit.

Abstract

Commonly joints problems (especially high strength bolt) were stiffness, ductility, and construction costs. This research was conducted with purpose to analyzed inner force and behavior that could be occurred on high strength bolted joints in steel frame using IWF profiles, such as stress, and reaction force-displacement. This study was divided into 2 step, first step was modeling on finite element software, and second step was analyzing the results and comparing it with the results from experimental study as validation base. In bolted joints model showed the best value on third trial with displacement value of 98,97 mm and reaction force of 41,57 KN. With validation to experimental results each one were 93,45% and 94,05%. Accuracy of hysteretic loop curve area was 98,46%.

Abstract

The limitations of spatial and temporal distribution of rain gauge networks causes inaccuracies in prediction of hydrological modeling. The availability of satellite rain data products is a potential to overcome this limitation. This studies objective is to compare the quality of rain data from the recording of the Manual Rainfall Recorder (MRR) with satellite data TRMM 3B42 which is entered in the HBV hydrological modeling. Calibration results shows that HBV modeling performance with MRR rain data input is better than TRMM. R2 and NSE values from MRR rain data input were 0.7153 and 0.7133 respectively with a mean error of 89 (mm / year). While the R2 and NSE values of the TRMM 3B42 satellite rain data input were 0.57 and 0.55 with a mean error of 305 (mm / year), respectively.

Abstract

The existence of a flood inundation rapid map is needed in flood mitigation. This research is intended to map flood inundation quickly by utilizing satellite image technology. Sentinel 2 Level 1C technology uses before and after the flood. The extraction process uses the methods of NDWI (Normalized Difference Water Index) and MNDWI (Modified Normalized Difference Water Index). The result is treated with a threshold value by dividing the pixel value into flooded and unflooded areas. The performance model shows that the MNDWI method is more accurate than the NDWI method in producing flood inundation maps. Thus, the results of the MNDWI method are practical and able to map flood inundation quickly.

Abstract

Floods are the most recurring natural disasters and impact human life, causing a severe economic downturn. The level of flood risk is a function of hazard and vulnerability. Flood risk-prone areas need to be identified to reduce the flood risk level. This study aims to assess flood risk based on spatial analysis results with Geographic Information Systems (GIS). The flood hazard map is built from remote sensing-based data in the form of a digital elevation model (DEM) applied using the frequency ratio weighting (FR) technique. Vulnerability maps are generated from social, economic, physical, and environmental data applied through techniques overlays weighted using the analytical hierarchy process (AHP). The resulting risk map shows that 21.93% and 6.40% of the total area are at a very high and high level of flood risk. This map is very useful for planning the flood management.

Abstract

Landslides are one of the natural disasters that often occur in the Upper Tanggul Watershed. This study aims to produce a landslide susceptibility map based on the Geographic Information System (GIS). Seven landslides conditioning factors used, namely land cover, river density, slope, aspect, elevation, curvature and Normalized Difference Vegetation Index (NDVI). Landslide susceptibility areas were mapped using the frequency ratio and weights-of-evidence methods. The accuracy of the landslide susceptibility maps generated from both methods is validated using the Area Under Curve (AUC). The estimation results of the AUC plot show that the susceptibility map using the frequency ratio model has an accuracy of 92,6% and the weights-of-evidence method has an accuracy of 90,1%.
