| Summary: | The economical design of culvert is a vital engineering decision due to the multiple
repetitive requirements in the construction of highway facility. It is therefore important to
seek for the cost effective design technique in order to reduce the project cost of
highways with high demand of such structures.
The economic design can be achieved through conventional culvert design practice, but
the maximum economy can only be achieved by optimizing the design. The optimization
procedure shall be applied from the hydrologic design, via the hydraulic design to the
structural design in order to yield hydrological, hydraulic, and structurally optimal
designed culvert structure.
The hydraulic design determined the size of the culvert and barrel number requirement
for the structure to control the passage of storm water flow through it, with risk,
economy, property damage, highway overtopping and damage, in mind.
Effective structural design is necessary for the resistance of the structure to various load
combination induced from the highway traffic, overfill material, backfill material,
hydrostatic thrust, self-weight, and the pressure due to the pipe flow condition.
When site conditions warrant, it is more economical to provide a multi-cell box culvert
structure than to embark on the construction of resources cons'uming bridge structure .
The hydraulic design is according to the method developed by American Association of
State Highway and Transportation Officials (AASHTO Methods) and Federal Highway
Administration. The structural analysis is done using computer frame analysis software
developed by Department of Civil and Structures, Manchester, United Kingdom. The
structural design is according to BD/37 "Design of buried concrete structures" and
BS8110 "Structural Use of Concrete: Part 1 Code of Practice for Design and
Construction". |
