What is bridge and its types?
There are 7 main types of bridges : Arch Bridge, Beam Bridge, Cable-stayed Bridge, Cantilever Bridge, Suspension Bridge, Truss Bridge, Tied Arch Bridge. The way in which the vertical/horizontal stresses are managed dictates the structure of different bridges.
What are the types of bridge?
There are six basic bridge forms: the beam, the truss, the arch, the suspension, the cantilever, and the cable-stay.
What are the classification of bridges?
1. Slab Bridge: When the span of bridge is 3 to 6m, slab bridge is used, It is also called culvert. 2. Girder bridge: When the span of a bridge is more, flooring is supported on RCC or steel girder.
What is RCC bridge?
A RCC bridge is a monolithic structure that is poured in place. Forms are placed, the reinforcing steel is placed into the forms and a concrete mix is poured into the forms. The rebar extends beyond the form to allow connection to the next section to be poured.
What is minor bridge?
A minor bridge is a bridge having a total length of from 6 m to 60 m. b. Major Bridge. A major bridge is a bridge having a total length of above 60 m.
What is the main function of bridge bearing?
A bridge bearing carries the loads or movement in both vertical and horizontal directions from the bridge superstructure and transfers those loads to the bridge piers and abutments. The loads can be live load and dead load in vertical directions, or wind load, earthquake load, etc., in horizontal directions.
What are the two ends of a bridge that support its weight?
They do it by carefully balancing two main kinds of forces called compression (a pushing or squeezing force, acting inward) and tension (a pulling or stretching force, acting outward), channeling the load (the total weight of the bridge and the things it carries) onto abutments (the supports at either side) and piers ( …
What is a bearing in civil engineering?
The horizontal angle between the reference meridian and the survey line is termed as bearing of the survey line. Magnetic Bearing: The angle made by survey line in a clockwise direction with reference to magnetic N-S line is termed as magnetic bearing of the line. …
What are the types of bearing in bridge?
Types of bridge bearings
- Rocker bearings.
- Elastomeric bearings.
- Sliding bearings.
- Spherical bearings.
What is type of fixed bearing?
Types of Bridge Bearings and their Details Rocker and pin bearings. Roller bearings. Elastomeric bearings. Curved bearings. Pot bearings.
What is a bearing pin?
The pin bearing is a fixed bearing with a pin connecting the upper and lower shoes, allowing rotational tracking in the vertical direction. The hardened pin roller bearing is a movable bearing consisting of a pin bearing with several rollers to allow tracking in both horizontal and vertical directions.
What is deck type bridge?
A deck type bridge is the one in which the roadway/railway floor rests on the top of the supporting structures, while a through bridge is the one where the roadway/railway floor rests on the bottom of the main load supporting structure.
What is the function of bridge deck?
The primary function of a bridge deck is to support the vehicular vertical loads and distribute these loads to the steel superstructure. The deck is typically continuous along the span of the bridge and continuous across the width of the span.
What is the average bridge clearance?
The federal government recommends that bridges on public roads have a clearance of at least 14 feet. This ensures that trucks shorter than the maximum truck height — 13 feet, 6 inches in most states — can pass underneath them safely.
Why is it called the bridge?
Traditionally, sailing ships were commanded from the quarterdeck, aft of the mainmast, where the ship’s wheel was located (as it was close to the rudder). When the screw propeller superseded the paddle wheel, the term “bridge” survived.

Is the bridge the front of the ship?
The bridge is the place on the ship where the captain and his crew manage the direction and speed of the ship, as well as other functions of the vessel.
