not specifically address detailed bridge design,it does serve as the basis for the timber design concepts and requirements used for bridges.Notation of the NDS as the source of design requirements in this chapter reflects references in AASHTO that specify the NDS as the most current source of timber design information for bridges (AASHTO 13.1.1). results for this questionWhat are the design methods of timber bridges?What are the design methods of timber bridges?5.3 DESIGN METHODS AND VALUES Timber bridges are designed according to the principles of engineering mechanics and strength of materials,assuming the same basic linear elastic theory applied to other materials.The method used for design is the allowable stress design method,which is similar to service load design for structural steel.BASIC TIMBER DESIGN CONCEPTS FOR BRIDGES results for this questionWhat are the specifications of a bridge?What are the specifications of a bridge?The primary specifications for bridge design in the United States are the Standard Specifications for Highway Bridges, adopted and published by the American Association of State Highway and Transportation Officials (AASHTO).l These specifications are published intermittently and are 5-1 BASIC TIMBER DESIGN CONCEPTS FOR BRIDGES

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 contechesEngineering the Design - Golden Gate Bridge,Highway and In 1921,engineer Joseph B.Strauss submitted a design for a bridge that would cross the Golden Gate Strait a hybrid bridge with a suspension span supported at each end by cantilever trusses.By 1929,consulting engineers Leon S.Moisseiff and O.H.Ammann had persuaded Strauss to accept the more graceful all-suspension bridge design that we see today.Pedestrian Bridge Design 7 Considerations for Architects Determine Width.Establishing the planned width for the trail and pedestrian bridge is a basicSite Conditions.Once the designer identifies the width,they must then decide the siting conditionsGeotechnical Analysis.Acquiring a geotechnical analysis is a prudent choice for learning siteAbutment Plan.A clear span over a physical,geographic site feature can be as simple asPermitting.Consider a longer span for water crossings,as it may help in the permitting process.Safety.Any pedestrian bridge design must be well engineered to provide safe,long-termDurability.Many pedestrian bridges are located in the harsh environment found at outdoor
