Construction stage analysis of Humber Suspension Bridge

Suspension Bridges can be classified into two groups according to the type of stiffening girders Two-hinged stiffening girder and continuous stiffening girder . Humber Suspension Bridges is contained in the two-hinged stiffening girder type. So the response of the middle span independent from the response of side spans.

Suspension bridgeWikipedia

A suspension bridge is a type of bridge in which the deck (the load-bearing portion) is hung below suspension cables on vertical suspenders. The first modern examples of this type of bridge were built in the early 1800s. Simple suspension bridges which lack vertical suspenders have a long history in many mountainous parts of the world.. This type of bridge has cables suspended between towers

schemes—a pair of suspension bridges and a pair of partially cable-stayed girder bridges. 3. Suspension Bridge Scheme This scheme is comprised of two single tower suspension bridges with 496m main spans (Fig. 2). The side spans of both bridges are 250m long. They both have two planes of cables. The towers are 100m above the deck.

Static analysis and simplified design of suspension

increase the rigidity of a suspension bridge is to transfer a part of stiffening girder rigidity to a suspension main cable. To give the suspension bridge more stable appearance the authors propose to use the cables of varying bending stiffness. The main cables can be made of standard section shapes or have a composite section.

Selection of a Structural System for a Three-Tower

AbstractA three-tower suspension bridge has an additional middle tower and a main span when compared to the conventional two-tower suspension bridge. Restriction between main cable and middle tower top is weaker and the force difference in the main cables on the two sides of the middle tower is large when one main span is fully loaded and the other one is not loaded.

Breaking Down Essential Parts of a Bridge Structure Term

Nov 24 2017 · Girder bridges are the most common types all over the world. At its simplest the form can be traced back to the simplest early log bridges. The two most common girder types are plate girders and box girders. A plate girder is made from separate structural steel plates instead of a single cross section. These are then welded together to create
