Abstract

Bridge is among the important part in transportation system. If the bridge damage or collapse it will definitely affect the transportation and distribution of human and goods. Thus it is very important to maintain bridge appropriately. Accordingly Bridge Management System (BMS) is a standard mechanism to evaluate condition and function of the bridge. The BMS also can be used to decide necessary treatment to maintain the bridge in specific circumstances. Further more Computer-Based BMS combined with integrated information system can shows us the priority scale to manage the bridge maintenance. But the visual assessment of bridge is a necessary step to evaluate general conditions of the bridge. This research conducted in four provincial bridge in Yogyakarta, which are Srandakan Bridge, Tinalah Brigde, Kebon Agung Brigde, and Glagah Brigde. Data from some other provincial brigdes were also included as a comparison. The evaluations is carried out by imposing 5 series of questions into the object (the damage element of the brigde). Then each element is weighted by point 1 and 0 according to its damage level from the lowest (level 5) until the highest (level 1), which mean the bridge is completely collapse. Its element or groups of element were weighted from 0 to 5 which 5 represent total score of 5 categories. The categories are Structure(S), Level of Damage (R), Damage Volume (K), Element Function (F) and Damage Affect (P). Assessment on the conditions, technical screening and economical evaluations, for Srandakan Bridge, Tinalah Brigde, Kebon Agung Brigde, and Glagah Brigde, resulting the following conditions: 4 (critical – replacement – priority scale 1), 3 (heavily damage – rehabilitation on waterway – priority scale 36), 3 (heavily damage – rehabilitation on upper structure – priority scale 23). Maintenance cost in the economic evaluation aspect is the estimation cost, not the real cost.

Abstract

Bridge plays a vital role in supporting life activity. A lot of bridges are required due to many watercourses running from mountain that also requires a lot of amount in the budget. Neglecting such problem may lead to traffic disturbance and discomfort. The purpose of this research is to assess the bridge condition and its components, to compose the handling priority program and the bridge component priority. The research was located in Kendari of the Province of Sulawesi Tenggara. Located above Kendari Bay, a crowd economic area, Kendari has the important downtown access road. NYSDOT (New York State Department of Transportation) Method and completed with AHP (Analytical Hierarchy Process) method were used to assess the bridge condition. The bridge component scoring was calculated using the AHP method. The calculated components were compiled using the matrix of paired-comparison by referring the importance value. The, bridge component scoring consisted of three categories: (a) first category: the structural component received direct traffic load (component distributing traffic load), which was given the first priority where the importance value was higher, (b). Second category: the structural component received indirect traffic load, (c). Third category: non structural component. Calculation method AHP for every bridge component was obtained through paired-comparison. Components with bad value were found in Pasar Baru Bridge, which was rated 3 for its extension component, paving surfaces, pavement and curb. The subsequent ones were the Tripping bridge, which was rated 4 for its extension joint component and Kadia bridge which was rated 5 on its main beam, abutment, deck and back wall. Both, NYSDOT and AHP methods resulted in same assessment figures. The proposed priority handlings in subsequent order for the three bridges were Pasar Baru Bridge, Kadia Bridge and Tripping Bridge. The condition indexes were 4,514 (Average), 5,722 (Good) and 6,083 (Very Good), respectively. The proposed handlings for Pasar Baru and Kadia bridge were rehabilitation and maintenance.

Abstract

To meet the need for good infrastructure of building construction, building new one is not theonly appropriate choice. Efficiency resulted from the functional substitution of existing building to be used with a new function can be a more precise alternative. The existing functional substitutio will result in the change of the building load. Based on the fact, it is necessary to evaluate the performance and the strength of structure at the existing condition to take new load and to calculate the strengthening required. The study is conducted on Building G of Campus III, Semarang University at Jl.Soekarno- Hatta, Semarang. A lecturing space in floor II was proposed to be functionally substituted into library room. It focuses on evaluating performance of structure, the strength of plate, beam, and column, and the bearing of foundation, existing condition based on SNI-2847-2002, earthquake load application based on SNI-1726-2002, and promoting a proposal for strengthening the structure required. The SAP 2000 is used to analyze the structure to gain the required strength value of U (ultimate). BETON 2000 is used to analyze the structure of existing condition to gain the existing strength value of R (resistance). The strengthening of the plate and beam is conducted by adding the Fiber Reinforced Polymer (FRP), while that of column is by adding an external reinforcement The result of the study indicates that the existing fc’ is 17 MPa and the fy is 390 MPa. From evaluation on the performance of structure, it can be known that the performance of servicing limit and that of ultimate limit of the building have really met the requirement of SNI-1726-2002. Based on the result of analysis on the structure of plates in floor 2, plates of A, C, E, and H need the strengthening of flexure ability. Beam in floor 2 : 1 A-E ; 1 E-I ; 2 A-E ; 2 E-I ; 3 C-E and ring beam : 0 A-C ; 0 C-E ; 0 E-G ; 0 G-I ; 3 C-E ; 3 E-I require the strengthening of flexure ability and shear ability. The strengthening of flexure and shear abilities by adding the FRP is found to be able to add the flexure and shearing abilities of plates and beam. The result of analysis on the strengthening of flexure ability by adding reinforcement shows that it can add the flexure ability of column. And form analysis on foundation, it can be known that foundation is able to bear new load so it does not require the strengthening.

Abstract

The economic growth and local advancement require increasing development of local infrastructure, including the air transportation. Selaparang airport in the Province of West Nusa Tenggara apparently has technical limitations for airside and landside development. Therefore, the local government and PT. Angkasa Pura I have formulated a policy to relocate a new airport with international standard, which is to be known as Lombok International Airport (BIL), to replace the Selaparang airport. Data used for the airport reconstruction analysis consisted of technical facilities required for the airside such as runway, taxiway and apron. The International Coorperation Aviation Organization (ICAO) and Federal Aviation Association (FAA) method were used reffering to Boeing Characteristic Airplane and the apron formulation capacity at peak time based on Japan International Coorperation Agency (JICA). Results of the analysis showed that the the reconstruction Phase I and Phase II of planned Lombok International Airport were classified as 4C and 4E, with 11 and 31 runways, respectively based on the ICAO standard by 2028. These figures were in accordance to the results of windrose analysis on system of up to 95% direction site usability factor. The planned airplanes using the airside facilty on Phase I were B 737-400 and MD 82 and B 747-400 on Phase II. The required length for runway of phase I is 3000 m, 4000 m for phase II, and 45 m runway width using the MTOW value. The taxiway dimension analysis was based on ICAO, FAA and Boeing Characteristic Airplane and resulted in 15 m taxiway for phase I and 23 m phase II. The analysis was divided into three analyses. The required apron dimensions for phase I stage 1 (2006, Phase I stage 2 (2016) and Phase II (2028) are 30.000 m2, 44.000 m2, and 123.520 m2, respectively.
