The Design and Construction of Anchor Block Pedestrian Cable-Stayed Bridge on Celebes Island

Abstract

The accessibility of Indonesian rural communities in remote areas is still minimal. The disparity of land and territory in Indonesia is so great that it has unique characteristics. Rivers, slopes, hills, and other obstacles separate each region. Until now, the Pedestrian Cable-Stayed Bridge has been a practical solution for connecting infrastructure in remote areas. However, availability and budget become constraints in its implementation. One of the steps that can be done is to optimize the size of the Anchor block. Optimization is needed in design and construction to make construction implementation easier at a cheaper cost. This paper aims to explain optimization in designing and constructing the Anchor Block Pedestrian Cable-Stayed Bridge with a case study in Celebes Island. Data collection methods include river typology, river currents, flood water levels, topography, community social and cultural data, people traffic, land data, and environmental data. Data processing uses Indonesian bridge planning standards to obtain the span length and height of the bridge, type of structure, material selection, and implementation method. Calculation and 3-dimensional modeling using SAP2000 software. The level of structural modeling is done to review the structure's behavior and control the structure's deformation value and the internal forces that occur in the structure. The research results show that weather and earthquake conditions that differ from other areas cause the potential for structural failure in Celebes Island to be higher. Optimization of the anchor block is done by reducing its dimensions, but it must still meet the technical rules. A reduction in size and volume of up to 10% can still withstand the required load. Earthquake loads, sliding, and overturning are essential parameters in designing and constructing Pedestrian Cable-Stayed Bridge on Celebes Island.
