What is the use of bridge design pattern?
The bridge pattern allows the Abstraction and the Implementation to be developed independently and the client code can access only the Abstraction part without being concerned about the Implementation part. The abstraction is an interface or abstract class and the implementer is also an interface or abstract class.
What makes a good bridge design?
The prototypical bridge is quite simple—two supports holding up a beam—yet the engineering problems that must be overcome even in this simple form are inherent in every bridge: the supports must be strong enough to hold the structure up, and the span between supports must be strong enough to carry the loads.

Three basic types of bridges used in transportation are: beam and truss bridges, arch bridges and suspension bridges.
Why is bridge needed?
A bridge helps maintain the natural shape of your face and may help support your lips and cheeks. The loss of a back tooth may cause your mouth to sink and your face to look older. More important, though, your dental health may suffer when teeth are not replaced. Teeth work together.
What is bridge in civil engineering?
A bridge is a structure built to span the physical obstacles without closing the way underneath, such as a body of water, valley, or road, for the purpose of providing the passage over the obstacle.
Why are bridges made?
A bridge is a structure built to span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross.

Bridge Designing. The designer should have first seen and studied many bridges in the course of a long learning process in order to design a bridge. He should know what type of beam may be suitable in the available conditions, either a beam bridge an arch bridge or a suspended one. He should also know the influence of foundation conditions on ...
What is a bridge plan?
A plan of the site showing all obstacles to be bridged such as rivers, streets, roads or railroads, the contour lines of valleys and the desired alignment of the new traffic route.
How does scale affect design?
The scale of the environment has an influence on the design. Environmental requirements regarding aesthetic quality. Bridges in towns that affect the urban environment and that are frequently seen at close range - especially pedestrian bridges - need more delicate shaping and treatment than bridges in open country.
Introduction to Bridge Design Pattern
A physical bridge provides connectivity between two points. The bridge pattern describes how to pull apart two software layers fused together in a single class hierarchy and change them into parallel class hierarchies connected by a bridge. The bridge pattern can be applied to scenarios where the class and what it does changes often.
Understand class diagram Bridge Design Pattern
Suppose you are writing software for Toyota Motors and need to represent the most sold car in the world – the Toyota Corolla. We’ll use an abstract class Corolla to represent the car. The concrete classes would represent each of the different models of the car. So far so good.
What are the components of a bridge?
If you're going to build a bridge, you'll need some help from BATS -- not the furry, winged mammals that so often live beneath bridges, but the key structural components of bridge construction: beams, arches, trusses and suspensions.
How far can a bridge span?
Modern beam bridges, for instance, are likely to span up to 200 feet (60 meters), while modern arch bridges can safely cross 800-1,000 feet (240-300 meters). Suspension bridges are capable of extending from 2,000-7,000 feet (610-2,134 meters). Regardless of the structure, every bridge must stand strong under the two important forces we'll talk ...
What are beam bridges used for?
They’re frequently used for monorail and raised transit systems. They’re also valuable for carrying utility cables and pipelines over short distances to homes, isolated communities, and subdivisions. Hint: Many beam bridges are historic structures, and there are limits as to how utilities can be conveyed over them.
What is an arch bridge?
An arch bridge has abutments at each end and is shaped as a curved or pointed arch. Arch bridge engineering is based on transferring the weight of the bridge and its loads partially into a horizontal thrust pushed back together by the abutments at either side of the bridge.
Why are bridges important?
Equally important, they allow vital utility lines, including cables and pipelines, ...
How far can a cantilever bridge span?
Structure of a cantilever bridge. Steel truss cantilever bridges were a major engineering breakthrough in the 1800s, since they can span distances of over 1,500 feet and are more easily constructed at difficult crossings, such as highways, deep waterways, or populated areas, using little or no ground support.
Why are trusses used in bridges?
A truss is used because it’s a very rigid structure that transfers the load from a single point on a bridge to a much wider area. Truss bridges can cross longer spans than basic beam bridges. Structure of a typical truss bridge. Truss bridges appeared very early in the history of modern bridges.
How many supports do you need to build a beam bridge?
In order to build a beam bridge (also known as a girder bridge), all you need is a rigid horizontal structure (a beam) and two supports, one at each end, to rest it on. These things support the downward weight of the bridge and any traffic traveling over it.
What did medieval architects improve on?
As centuries went on, medieval architects improved on earlier designs, creating arch bridges with narrower piers, thinner arch barrels, pointed arches, and increased arch spans. Renaissance architects not only built some of the most structurally sound bridges in history, they also created some of the most beautiful.
What is a beam bridge?
A beam bridge, with forces of tension represented by red lines and forces of compression by green lines. Encyclopædia Britannica, Inc. When a bridge is made up of beams spanning between only two supports, it is called a simply supported beam bridge.
What is the purpose of efficiency in bridge design?
Efficiency is a scientific principle that puts a value on reducing materials while increasing performance.
How does a beam bridge work?
A beam carries vertical loads by bending. As the beam bridge bends, it undergoes horizontal compression on the top. At the same time, the bottom of the beam is subjected to horizontal tension. The supports carry the loads from the beam by compression vertically to the foundations.
What is elegance in design?
Finally, elegance is a symbolic or visual principle that puts value on the personal expression of the designer without compromising performance or economy. There is little disagreement over what constitutes efficiency and economy, but the definition of elegance has always been controversial. Britannica Quiz. Bridge Quiz.

Generally speaking, bridges can be divided into two categories: standard overpass bridges or unique-design bridges over rivers, chasms, or estuaries.
What is bridge construction?
A structure built to span and provide passage over a river, chasm, road, or any other physical hurdle. The function required from the bridge and the area where it is constructed decides the design of the bridge.

What is an integral abutment bridge?
Integral abutment bridges are joint-less bridges where the deck is continuous and connected monolithically with the abutment walls. These bridges accommodate superstructure movements without conventional expansion joints. With the superstructure rigidly connected to the substructure and with flexible substructure piling, the superstructure is
What was the first bridge made of?
The first bridges made by humans were probably spans of wooden logs or planks and eventually stones , using a simple support and crossbeam arrangement. Most of these early bridges could not support heavy weights or withstand strong currents.

The first book on bridge engineering was written by Hubert Gautier in 1716. With the Industrial Revolution in the 19th century, truss systems of wrought iron were developed for larger bridges, but iron did not have the tensile strength to support large loads. With the advent of steel, which has a high tensile strength, ...
