What are the different types of load bearing capacities?What are the different types of load bearing capacities?Typical load bearing capacities (at ULS) are tabulate below. Further guidance on the types of bearings and their usage can be found in Guidance Note 3.03 . Elastomeric bearings normally consist of a number of rubber layers separated by steel plates. These are normally laid in pads or strips and are ideally suited for small structures.Bridge articulation and bearing specification b elevation typical expansion bearing typical What is the temperature range for elastomeric bearings?What is the temperature range for elastomeric bearings?Design bearings for movements associated with a temperature range of 150F (-30F to 120F) and a base construction temperature of 45F. Design elastomeric bearings for service loads and without Dynamic Load Allowance (IM). Uplift at bearings is not permitted.NOVEMBER 2017 LRFD BRIDGE DESIGN 14-1 What should be included in a bridge bearing specification?What should be included in a bridge bearing specification?The bridge designer should specify the expansion joints in a similar manner to bearings, giving details of characteristic and design values of displacements to the joint designer. Annex B of BS EN 1993-2 contains guidance for the preparation of a technical specification for expansion joints.Bridge articulation and bearing specification b elevation typical expansion bearing typical

How are expansion joints and bearings used in bridges?How are expansion joints and bearings used in bridges?Expansion joints and bearings provide mechanisms to accommodate movements of bridges without generating excessive internal forces. This section provides guidance on joint and bearing selection and the movement and loads that must be used in their designs.NOVEMBER 2017 LRFD BRIDGE DESIGN 14-1Standard design drawings WSDOT
