Bridge Bearings - California Department of Transportation

Bridge Bearings Introduction AASHTO defines a bearing as a structural device that transmits loads while facilitating translation and/or rotation.1 In the past Caltrans has used a variety of bearings with varying degrees of success.These include rockers,rollers,pins,pots,steel girder hangers,PTFE/elastomeric,and elastomeric pads.Chapter 9 Bearings and Expansion Joints ContentsSteel Superstructure.Plate Girder Box girder 300 ft 900 ft 300 ft 700 ft expansion joint table to be less than the minimum installation width of 1½ inches .This condition is slower to respond to an imposed thermal stimulus than would a steel plate girder bridge composed of many relatively thin steel elements.Composite Girder - an overview ScienceDirect TopicsThe structural steel used in the test was a high-strength steel HPS70W having a nominal yield stress of 482 MPa (70 ksi).The general layout and dimensions of composite plate girder G2 are shown in Figure 7.8.Similar to G1,the composite plate girder G2 had an overall length of 12,801 mm and a length between supports equal to 12,192 mm.

Design Considerations for Pedestrian Truss Bridge Structures

SitingFunctionalityDesignConclusionReferencesThe layout and design of a prefabricated steel truss bridge begins with a site reconnaissance to determine the bridge width and length (also known as span) dimensions.A simple site investigation paying close attention to abutment constraints,flood marks,the size of upstream logs,streambed strata,and drift locations is advised.A geotechnical investigation is recommended.Reference the CE News article titled \Articulated Concrete Block Design,\ dated August 2010 for more information aSee more on contechesEconomical Steel Plate Girder Bridges - UMDASTM A588 weathering steel used in appropriate environments.The cost advantage of unpainted weathering steel designs compared to painted high-strength steel designs can range from 2 to 11% for the main girders,even though the unit cost of A588 is the highest of the three commonly used bridge steels.Unpainted weathering steel is lessENCE717 Bridge Engineering Outline of LRFR for Steel ENCE717 Bridge Engineering Load and Resistance Factor Rating (LRFR) for Steel Bridges Chung C.Fu,Ph.D.,P.E.(http best.umd.edu) Outline of LRFR for Steel Bridges General AASHTO LRFR Rating for steel truss bridges Rating for steel line girders Rating for refined steel bridge analysis Rating factors for steel Eccentric Load Coefficient of Live Load Normal Stress of Jan 01,2012·It is a three spans of continuous composite box-girder bridge with corrugated steel webs and constant cross-section .The spans are 47m ,52m and 47m .The top flange width of the box-girder is 16.85m ,the thickness is 25cm; the width of the floor is 11.85m ,the thickness is 22cm;the height is 3.2m;The webs are corrugated steel webs whose
