design approaches. The one design involves the use of load-carrying laminates in the aeroshells and webs for providing shear stiffness and buckling resistance. The other design constitutes of two aeroshells bonded to a load-carrying box girder. Sandwich structures are used extensively in the aeroshells and are also often used

GANTRY CRANE SPECIFICATION

design criteria and parameters, Konecranes meets all local requirements and safety regulations so that they can be met by using the above norms. 5. Steel structure Crane girders are manufactured from hot rolled wide flange profile sections or welded from certified steel plates to form a BOX type girder. The vertical deflection due to

TITLE 2. STRUCTURAL ANALYSIS

curve on plan it may be possible to use double-beam or double-girder open sections that are designed to provide sufficient resistance to torsion resulting from eccentric actions. However, in hyperstatic structures there are often open-section members (transverse beams for grids or twin box bridge decks, for example) being subject to

Comparative Bridge Costs - California Department of ...

NOTE: Removal of a box girder structure costs from $10 - $20 per square foot. * "Price/SQFT" is calculated using "Bridge Costs Only" as defined by the Federal Highway Administration. The "Bridge Cost Only" is the sum of the "Superstructure" and "Substructure" bridge items, listed in Chapter 11 of the Bridge Design Aids Manual, multiplied by the ...

Guidance Note Shear connectors No. 2 - Steel Construction

Note that in steel box girders with composite flanges, there will be a concentration of shear transference local to the box webs. Shear studs will need to be arranged to suit this, resulting in a higher density of connectors above the webs - see EN 1994-2 Clause 9.4. Size of shear connectors Clearly, the design for shear transfer will have
