Planning for Bridge Construction including Sequence and Steps of Planning
Planning for bridge construction is required as it has huge impact on life of people. Social, scientific and technological dimensions for bridge construction must be considered. The decision of providing a bridge across any barrier is to facilitate the community residing ...
Accelerated Bridge Construction -Features, Advantages and Sequence of Construction
Accelerated bridge construction (ABC) uses innovative planning, design, resources and techniques to accelerate the bridge construction without compromising safety. This method also focuses on bringing down traffic disruption to the maximum. This approach is applied to new projects or to replace ...
Types of Bridges Based on Span, Materials, Structures, Functions, Utility etc.
There are various types of bridges classified based on span, materials, types of bridge structures, functions, utility and position etc. A bridge is structure which allows passage over an obstruction. The obstructions may be river, valley, rail route or road way ...
BALANCED CANTILEVER METHOD OF BRIDGE CONSTRUCTION
Balanced Cantilever method of Bridge Construction: Balanced cantilever method of bridge construction is chosen where a bridge has few spans which range from 50 to 250m. Construction begins at each bridge pier. Special formwork is positioned and cast-in-situ pier segment is ...
STEPS IN ANALYSING A BRIDGE
STEPS IN ANALYSING A BRIDGE The analytical process for structure of bridges can be broken down to six main steps:Idealise the structure Form a model Idealise the loading in a form suitable for the model Solve the resulting equation Interpret the ...
METHODS OF BRIDGE CONSTRUCTION
METHODS OF BRIDGE CONSTRUCTION: Before a bridge can be built an appropriate method of construction must be chosen. The decision is made by the design team. The principle factors considered by the design team when chosing a suitable method of construction ...
ADVANTAGE OF CONTINUOUS OVER SIMPLY SUPPORTED MULTI-SPAN DECK
Advantages of continuous multiple-span deck over simply supported multiple-span deck Movement joints are normally added to bridge structures to accommodate movements due to dimensional changes arising from temperature variation, shrinkage, creep and effect of prestress. However, the provision of excessive ...
INSPECTION OF A BRIDGE STRUCTURE
INSPECTION OF A BRIDGE STRUCTURE: Once a bridge is opened for use, management begins and carries on for the life of the bridge. Hence, the bridge must be regularly inspected and maintained for the benefit of its users. There are three levels ...
