Abstract

Flutter is one of the most notable aeroelastic phenomenons in long-span bridges and needs to be evaluated carefully in the design phase as it might cause catastrophic structural failure. Numerical and experimental methods can investigate flutter on a deck bridge. However, the numerical methods could be less accurate for a complex-shaped deck, such as a deck equipped with railings and bluff cross-section bridges. Therefore, experimental methods using wind tunnels are more convenient for validating the flutter phenomenon on a bridge deck. The study was conducted to understand the effects of long-span bridge cross-section shape on the critical flutter speed analysis. The method is a hybrid numerical procedure, combining a wind tunnel test to identify the flutter derivatives coefficients and a numerical method to determine the critical flutter speed limit. The testing method developed in this research was used for both torsional and coupled–flutter cases. In the case of Testing Model I (thin plate), the developed method predicted the critical flutter speed of 16.7 m/s, which is close to the theoretical calculation using the thin-plate approach of 18.04 m/s. While in the case of testing model II (bluff body), the predicted flutter speed is 14.8 m/s which is close to the experiment result of 15 m/s. In the study case of the First Tacoma Bridge, the developed method could accurately predict the critical flutter speed with an error of only 4.3%. Hence, according to the study, the developed analysis method can accurately predict the flutter speed for both torsional and coupled flutter. Keywords: bridge, aeroelastic, flutter, wind tunnel, numerical.

Abstract

Corrugated steel structure consist of three types, i.e. standard (corrugation 152 by 51), deep (corrugation 381 by 140) and super deep (corrugation 500 by 237), but only the standard and deep types that has already produced in Indonesia. The steel structure can be used as a bridge structure in combination with the embankment on the top using common fill material. However, several flyover projects in Indonesia used corrugated steel structures with a span of 22 meters to 26 meters and lightweight foam mortar to replace the common fill. This study was conducted to perceive the effect of the use of lightweight foam mortar on the strength of the structure. The evaluation was carried out by simulating the corrugated steel structure with a span of 22 meters and a thickness of 9 mm either with common fill or lightweight foam mortar using finite element software. Furthermore, the strength parameters for each fill material was calculated refer to the Canadian Highway Bridges Design Code. There are four structural strength parameters that was reviewed, i.e. buckling strength, seam strength, plastic hinge, and displacement. The values of these parameters must be greater than 100% that indicates the force occurs is less than the allowable value, meaning the structure is in a safe condition. The calculation result of each strength parameters by using lightweight foam mortar respectively are 358%, 235%, 458% and 319%. As for that using common fill respectively are 99%, 120%, 37% and 27%. These results show, the application of lightweight foam mortar will increase the value of the structural strength parameters that make the bridge structurally safe. Key words: corrugated steel structure, lightweight foam mortar, common fill, buckling strength, seam strength, plastic hinge, displacement.

Abstract

This research aims to evaluate the stability of the slope by considering the rock mass characterization. The research location was conducted on the Planjan–Baron–Tepus section at STA 7+000 to STA 9+725, with limestones dominating the lithology. The data collection method begins with determining rock mass quality based on rock mass classification using the Geological Strength Index (GSI) of limestone introduced by Marinos (2010). The results of testing the physical and mechanical properties of rocks and the quality of rock mass will be used as input parameters in the slope stability analysis. The results showed that the rock mass quality in the research area varied from "good" condition at STA 9+075, "fair" condition at STA 7+825, to "poor" condition at STA 8+475. Based on the slope stability analysis using the finite element method and the Generalized Hoek-Brown failure criteria, the result of the slope analysis at three locations representing the rock mass quality was a stable (safe) condition without seismic loads and with seismic loads. Key words: slope stability, rock mass quality, geological strength index, limestone, finite element method.

Abstract

In May 2006, an earthquake occurred in Bantul Regency and showed liquefaction phenomena like lateral spreading and sand boiling. The 2019 Indonesia Liquefaction Vulnerability Zones Map identified the Bantul coast as a moderate to high liquefaction risk zone. This research aims to determine the potential for liquefaction due to soil movement in the Kretek 2 Bridge construction area, Bantul Regency, D.I Yogyakarta, nearby the opak fault as a seismic source. The preliminary study used the grain size analysis approach by Tsuchida (1970) shows soils predominantly in the most liquefiable category and others in the potential liquefaction category. Youd et al. (1979) and Hakam (2020) approaches also show that liquefaction vulnerabilities extend through most of the boreholes. The simplified procedure by Idriss and Boulanger's (2008) analysis shows a liquefaction potential at a depth of 0 to 16.5 m with a thickness of 1.5 to 9 m, except for BH-4, which does not have any liquefaction potential. Meanwhile, the quantitative and qualitative analysis results using the liquefaction severity index showed that BH-3, BH-9, BH-12, and BH-13 had very low categories. In BH-1, BH-2, BH-5, BH-6, BH-7, BH-8, and BH-14 had low category. While BH-11 is in the moderate category and BH-10 is in the high category. The quantitative and qualitative analysis results were then drawn into a microzonation map of ​​the Kretek Bridge 2 liquefaction severity area to facilitate stakeholders in ensuring the safety of the foundation system used. Keywords: kretek 2 bridge, preliminary, simplified procedure, liquefaction severity index, microzonation map

Abstract

Numbers and fatality of casualties in Indonesia is a very serious problem that has to be solved as soon as possible. Data shows that 3 or 4 casualties die every 12 accidents per hour. The high risk occurs because of many factors i.e. humans, condition of road, vehicle, environment, technology, and weather that can be explained with Risk Exposure. The aims of this study are to determine the value of Risk Exposure in order to improve road safety in Indonesia based on accident fatality and then propose recommendations in order to reduce the number and fatality of the accident risk. Complete, accurate, and up to date data is collected from Korps Lalu Lintas Polri, 2019 and Statistics Central Bureau in year 2010-2019 in all provinces in Indonesia. Data from year 2010 up to year 2019 can be considered as a normal data, whereas data during pandemic conditions can be assumed as an up normal data because of many traffic policies applied as need at that time. Descriptive statistics indicated that Risk Exposure Value (REV) based on accident fatality to population number, vehicle number, driving license ownership, and various roads surface pavement conditions increase every year. From the REV, then the practice actions that have to be done soon are education to the divers, implementation of road furniture, and step by step installation of ITS as needed. The results of this study are important because the study reviews from another point of view rather than that most accidents are caused by human error and can then be used as a basis for real follow-up in the field. Key words: risk exposure, risk exposure value, road safety, Indonesia

Abstract

In order to achieve sustainable development and offset the high demand for improving the quality of roads as one of the socio-economic infrastructures, an optimal strategy is required. The use of Reclaimed Asphalt Pavement (RAP) has been developed as an effort to minimize aggregate waste due to asphalt pavement production. This study aims to estimate the cradle to gate asphalt road life cycle impact through Life Cycle Assessment (LCA) with OpenLCA software and Recipe 2016 Midpoint (H) method, to compare the impact between asphalt with natural aggregate and asphalt contain 50% RAP, and to analyze the components of activities that contribute the most to the impact. The case study is rehabilitation project of national asphalt roads in West Java Province with 1 km asphalt road functional unit. The result shows that the use of 50% RAP levels can reduce the impact of global warming (GWP) of 1,05 ton CO2 eq, fossil resource scarcity (FRS) of 19,60 ton oil eq, human carcinogenic toxicity (HCT) of 0,25 ton 1,4-DCB, and human non-carcinogenic toxicity (HnCT) of 1,79 ton 1,4-DCB compared to asphalt without RAP, while the impact of fine particle formation on asphalt with 50% RAP is 0,02 ton PM2,5 eq higher than asphalt without RAP. Diesel is the main activity that contributes the largest emissions to most impacts, and fuel efficiency efforts can reduce the overall impact.
