| Summary |
"In this study of the continuous tied-arch bridge, having one main span and two equal side-spans, the following items are endeavored: (1) To set up the total internal work equations and to find the values of the unknown forces or redundants. (2) To compute to maximum moments for design and to complete the design of the super-structure for one bridge. Details, such as the gusset plates, rivets, connection angles, etc., are not designed; the effect of such being allowed in the design for dead load as a certain per cent for details. (3) To set up hypothetical conditions for other bridges of different span lengths and to construct the influence lines of the unknown forces of each. (4) To compare the different bridges upon the basis of their influence diagrams"--Synopsis, leaf 3. |
