Abstract

BH 915 is a two-span bridge located at km
396+427 between Stasiun Muaraenim-Muaralawai
Divre III Palembang. The span length of the bridge is
25 m and 50 m with the initial design based on RM
Bukit Asam. Each bridge will experience a decrease
in condition due to increasing age, operating
expenses, and environmental conditions. This
degradation analysis cannot only be carried out with
inspection procedures that produce qualitative values,
but also requires quantitative values. Therefore, in the
discussion of this paper, it discusses the analysis of
the value of the safety factor on the BH 915 bridge
due to loading with a combination of dead load and
live load in the form of RM 1921 and Existing with a
comparison to the initial design of the bridge using
RM Bukit Asam loading.
From the results of the analysis, BH 915 with
a span of 25 m under normal conditions has a safety
factor value of 0.91 when loaded with RM 1921, 1.25
when loaded with locomotives, 1.58 when loaded with
locomotives, and 1.92 when loaded with carriages.
BH 915 with a span of 50 m under normal conditions
has a safety factor value of 0.89 when loaded with
RM 1921, 1.31 when loaded with locomotives, 1.71
when loaded with locomotives, and 1.96 when loaded
with carriages. When it is assumed that the quality of
the bridge is reduced by 25% (moment increases by
25%), the value of the safety factor has decreased by
20%.
