Define Bridge Bearings Form

Bearing properties specify data for bridge bearings. Bearing properties are used in abutment, bent and hinge assignments to the bridge object. At abutments, bearings are used in the connection between the girders and the substructure. At bents, bearings are used in the connection between the girders and the bent cap beam. At hinges, bearings are used in the connection between the girders on the two sides of the hinge. A bearing property can be specified as a Link/Support property or it can be user defined. The user defined bearing is recommended. The user defined bearing allows each of the six degrees of freedom to be specified as fixed, free or partially restrained with a specified spring constant.
