| Summary: | Since the Romanian Empire until twentieth century, the arch structures are widely
applied in all fields of engineering constructions, from bridge, subways, and
underground structures to military shelters. The loadings are altered to fulfill the
specific demand in transportation systems, materials quantity and the analysis
methods. Therefore, we should improvise our understandings on structural
behaviour.
The behaviour of buried structural arch for span 10m to 30m are analyzed with finite
element method. The structural behaviours include the axial force, shear force and
bending moment in both distributions diagram and magnitude. By applying three
types of load cases, that is self-weight, fill weight and live load, the behaviours of
arch for axial force, shear force, bending moment, horizontal and vertical reaction are
observed. This research provides a better understanding about the behaviours on
buried arch with various rises to span ratio.
From the analysis on the behaviours of buried arch by finite element method, the
change in arch rise to span ratio for three types of load cases show the increment in
maximum axial force, shear force, bending moment, horizontal and vertical reaction.
Investigation for buried arch structures with different rise to span ratio is importance
for future designs of arch structures, with higher quality, durability and strength.
Lastly, future design of arch structures will be able to achieve longer life cycle, cost
effectiveness and environmental friendly. |
