Modular expansion joints are used when the movements of a bridge exceed the capacity of a single gap joint or a finger type joint. A watertight system, invented by the Swiss company Mageba, is designed on a modular basis and can be tailored to satisfy the specific requirements of almost any structure.

Fatigue design of modular bridge expansion joints by Robert J. Dexter Download PDF EPUB FB2

Abstract This paper presents results of an experimental investigation on the fatigue performance of the welded multiple support bar modular bridge expansion joint (MBEJ) used for the recent Jacques Cartier Bridge rehabilitation in Montreal.

Three identical subassemblies of the modular joint system were tested in by: 7. Several premature fatigue failures of modular bridge expansion joints have occurred in Europe and the United States.

The principal causes of such failures have been poor detailing (for instance, choice of fillet welds instead of full-penetration welds) and the tendency to reduce production costs by adopting larger beam by: Abstract This paper presents results of an experimental investigation on the fatigue performance of the welded multiple support bar modular bridge expansion joint (MBEJ) used for the recent Jacques.

D.S. Brown Steelflex ® Modular Expansion Joint Systems have gained overwhelming worldwide acceptance for accommodating and sealing large joint movements on bridge structures.

By incorporating the results of recent research activities, each joint system is designed to provide watertight, fatigue resistant, long-term, maintenance-free performance. The modular expansion joint chosen for the implementation of the early warning monitoring system is part of the Martinus Nijhoff Bridge.

This bridge is located in the centre of the Netherlands, on the highway A2 that makes the connection between the cities of Cited by: Experimental and analytical research was performed to develop performance-based specifications and commentary for the fatigue design of modular bridge expansion joints (MBEJ).

Field testing was conducted on MBEJ installed at four different locations to measure static load distribution and the dynamic response of MBEJ to truck loads. Fatigue damage readily occurs because it is directly subjected to repeated load.

In this paper, fatigue and static loading tests were conducted on modular bridge expansion joint (MBEJ). This is an innovative type of shallow-buried modular bridge expansion joint, and the anchoring depth is reduced by 40%% compared with traditional ones.

For long span bridge structures mainly joints belonging to the family of modular expansion joints are used in the Netherlands.

The basic concept of modular expansion joints is over 30 years old and consists of center beams placed in transverse direction of the bridge supported by beams in traffic direction.

FATIGUE DESIGN OF MODULAR BRIDGE EXPANSION JOINTS Experimental and analytical research was recently performed to develop performance-based specifications and commentary for the fatigue design of modular bridge expansion joints (MBEJ). The resulting proposed fatigue-design and test specifications resulting from this research are discussed.

The design of the watertight TENSA®MODULAR expan-sion joint, which was invented by mageba, has been continually developed in recent decades. The current 4th generation of the system fully accommodates these high demands. The TENSA®MODULAR expansion joint was developed, as the name suggests, as a modular system, with joints for specific.

The work was divided into two tasks. The first task was a literature review and evaluation of existing methods for fatigue design of modular joint systems. The second task consisted of a wide range of finite element analyses of the particular joint, and correlation of the computed results in existing design models and observed behavior.
