Use of Longitudinal Expansion Joints in Wide-Bridge

10/10/2016· Unfortunately, the introduced longitudinal expansion joint can result in deterioration similar to that resulting from using transverse joints at bridge abutments and piers. The reason that longitudinal expansion joints are used in wide bridges is related to concerns about deck cracking resulting from constrained expansion and contraction. The main objective of this research was to

Choice of Deck Joint Bridge Design

Choice of Deck Joint. Current practice is to make decks integral with the abutments. The objective is to avoid the use of joints over abutments and piers. Expansion joints are prone to leak and allow the ingress of de-icing salts into the bridge deck and substructure. In general all bridges are made continuous over intermediate supports and

Bridge Expansion Joint Installations Freyssinet UK

Bridge expansion joints (or movement joints) are designed to enable continuous traffic between two structures and are necessary to accommodate structural movements due to creep and shrinkage effects, temperature variations or deformations under live load. They are suitable for reinforced concrete, pre-stressed concrete, composite and steel structures, and particularly for bridge decks. Bridge

TABLE OF CONTENTS JOINTS CHAPTER 14

The maximum roadway surface gap in a transverse deck joint, measured in the direction of travel, shall be limited to 4 inches. The opening of tooth expansion joints may be larger than 4”. Longitudinal Deck Expansion Joints: Longitudinal deck expansion joints should be avoided for bridge

Modular Expansion Joints Bridge Joints

Modular expansion joints for longitudinal movements of 80 mm to 1,200 mm can be widely applied on the bridges which are slope, wide, curved and skew. They are used in highway bridge decks, bridgehead and other places to prevent bridges from appearing cracks cause by climate change. It also can be used in expressway.

Bridge Deck Joints and Deck Joint Seals

Bridge Deck Joints and Deck Joint Seals Introduction Although often thought of as static, highway structures are continually in a state of motion. Expansion and contraction caused by temperature changes, shortening and creep caused by prestressing, deflections caused by live loads, and longitudinal forces caused by vehicular traffic all combine to produce nearly continuous motion in

Bridge articulation and bearing specification

Longitudinal forces are taken by both the fixed and guided bearing at the “fixed” end of the span. In a wider deck, it would be preferable to locate the fixed bearing closer to the centre of the deck so as to minimise the relative transverse movement and thus limit the movements to be accommodated by the expansion joint.

Bridge Joints Bridge Joint Association

Bridge expansion joints have to function as “riding plates” to carry the imposed traffic loads and also accommodate the thermal movement, shrinkage, pre-stress creep and rotation of the deck. These joints can be simple buried or asphaltic plug joints or complex mechanical joints according to the range of movements to be accommodated. The expansion joint should give good riding

use construction procedures that eliminate the joints from the bridge deck. The two most commonly used methods are called integral and semi-integral construction. These two terms are sometimes collectively referred to as jointless bridge construction. In integral construction, concrete end diaphragms are cast monolithically with both the bridge deck and supporting pile substructure. In order
