This document is a standard developed by the AASHTO NSBA Steel Bridge Collaboration The. primary goal of the Collaboration is to achieve steel bridge design and construction of the. highest quality and value through standardization of the design fabrication and erection. processes Each standard represents the consensus of a diverse group of professionals. It is intended that Owners adopt and implement Collaboration standards in their entirety to. facilitate the achievement of standardization It is understood however that local statutes or. preferences may prevent full adoption of the document In such cases Owners should adopt these. documents with the exceptions they feel are necessary.

All rights reserved, Steel Bridge Bearing Design and Detailing Guidelines.
Introduction, The purpose of this guide is to present steel bridge bearing details that are cost effective functional and. durable Three major types of bridge bearings are presented. 1 Elastomeric bearings, The details are for steel reinforced elastomeric pads however much of the content is directly. applicable to fiberglass reinforced plain and cotton duck pads as well. 2 High Load Multi Rotational bearings HLMR, The details include pot disc and spherical bearings. 3 Steel bearings, The details are primarily used for fixed bearing lines. These bearing categories are sufficient to cover the vast majority of structures in the national bridge. inventory Special bridges may require different bearings. This guide is not intended as a stand alone document and does not supersede the AASHTO specifications. This guide does not include seismic isolation bearings This is due to the complexity of the various. approaches to individual isolation bearing designs. This document contains many guidelines that are based on provisions of the AASHTO design and. construction specifications Designers should note that changes made to the AASHTO specifications. after the publication of this document may be in conflict with the guidelines contained herein In this. case the provisions in the AASHTO specifications shall take precedence over the guidelines in this. iv Copyright 2004 by the AASHTO NSBA Steel Bridge Collaboration.

Elastomeric Bearings, 1 1 General Commentary, This section is intended to assist in the design and Elastomeric bearings have a low initial cost.
detailing of elastomeric bridge bearings The when compared to other bearing types and. information included is intended to permit efficient require virtually no long term maintenance. fabrication installation and maintenance of these, This guideline document contains design. guidance for areas that are not specifically, addressed in the AASHTO specifications. 1 2 Reference Documents, AASHTO LRFD Bridge Design Specifications.

1 3 Basic Assumptions Commentary, This document makes the following design and Some states prefer to attach the bearings to the. detailing assumptions for elastomeric bearings beam by welding and others prefer bolting. Both methods are acceptable refer to individual, 1 The bearings are normally vulcanized to a top. state requirements Welded attachment allows, plate or sole plate. for minor adjustment during installation and is, 2 The bearings are attached to the girder by field. often the most economical design Bolting, welding or bolting.
provides limited damage to coating systems and, 3 Masonry plates and anchor rods are not. allows for easier removal in the future, normally required. 4 The bearing bears directly on the concrete Several states design expansion bearings without. substructure a connection to the girder The bearing is held in. 5 Lateral forces on expansion bearings are place by friction alone There have been isolated. restrained by means of friction keeper angles problems with elastomeric bearings slipping. or concrete keeper blocks keys Lateral forces and or walking out from under beams Research. on fixed bearings are restrained by anchor rods has shown that paraffin used in natural rubber. bearings to prevent ozone degradation can bleed, out causing a large drop in friction values. Several states incorporate recesses and keeper, assemblies to prevent the bearing from slipping. however these methods are typically not cost, effective This problem can also be solved by.
specifying neoprene for the elastomer since, paraffin is not required in neoprene bearings. See Research Report 1304 3 An Experimental, Study of Elastomeric Bridge Bearings with. Design Recommendations J V Muscarella and, J A Yura 1995. Several states design short simple span bridges, using expansion bearings only This method. reduces the movement at each bearing by half, Copyright 2004 by the AASHTO NSBA Steel Bridge Collaboration 1.
All rights reserved, Steel Bridge Bearing Design and Detailing Guidelines. 1 4 Design and Detailing Recommendations, 1 4 1 Design Commentary. The design of elastomeric bearings is the States currently use both Method A and Method. responsibility of the design engineer The design B as outlined in the AASHTO specifications. should follow the provisions of the AASHTO For specific information regarding the. specifications requirements of the individual state DOTs refer. to each state s design procedures, It is recommended that AASHTO Method A be. used for design since it is less complicated and, has fewer testing requirements Bearings. designed using Method A have an excellent, performance history.
1 4 1 1 Bearing Shapes Commentary, Elastomeric bearings can either be round or The AASHTO Design Specifications allow the. rectangular use of both round and rectangular bearings. Round bearings are best used for standardization, of bearings by an agency since only one. dimension can vary in plan Round bearings are, recommended for curved and larger skewed.
