Stiffness Method for Frame Structures For frame problems (with possibly inclined beam elements), the stiffness method can be used to solve the problem by transforming element stiffness matrices from the LOCAL to GLOBAL coordinates. In general, these components may be classified either as parts of a bridgeor as parts of a bridge substructure superstructure. When piling cast as determined by test piles are of such lengths as to cause an increase in the weight of steel used per linear foot of pile over that required in the. Value-in-place estimates are not published separately for individual series until data for the series are available. The cost competitiveness of long-span bridges can be se- cured in terms of direct cost saving and reduction of in- direct social costs by shortening the construction period and thus moving up the entrance in service of the bridge.
