Abstract: This study is intended to analyse the condition of Maos steel-truss railway bridge, that has been known as ‘Bangunan Hikmah’ (BH) 1549 railway bridge, in order to obtain clarity of its status based on logical basic rules inspection and new criteria in the 90’s era. Technically, the goal of this study is to inspect feasibility or reliability of the railway bridge after >120 years old. This study was conducted by analysing the BH 1549 railway bridge that has been developed in year 1894 based on Axles Load Scheme (Skema Beban Gandar/SBG) loading specification that has been proposed in year 1988 and by utilising Load and Resistance Factor Design (LRFD) method that has been proposed in year 2005. By feeding the dynamic loading from SBG 1998, then the member force could be calculated. The calculation was carried out by using SAP2000 V14 Software. Besides that, Failure Index (FI) and Reliability Index (RI) were also could be determined. Result of this study shows that the rail bridge has RI value in a range of 2.0328-11.1249. According to Indonesian National Standard (Standar Nasional Indonesia/SNI) 03-1729-2002 for bridge element, minimum standard value for RI is 3 while minimum standard value for joint is 4.5. Hence, it could be concluded that the investigated rail bridge has several elements that are under standard but for the entire rail bridge, the RI value is still quite good.
