Statics of Structural Supports

1 TYPES OF FORCESE xternal Forces actions of other bodies on the structure under Forces forces and couples exerted on a member or portion of the structure by the rest of the structure. Inter-nal forces always occur in equal but opposite of Structural Supports2 SupportsDifferent types of Structural Supports are shown in Table 1. Some physical details for the idealized support conditions of Table 1 are shown in Figs. 1 : Structural roller Supports are assumed to be capable of resisting normal displacement in either direction3 Table 1.

Note that the bending moments are most evenly divided into positive and negative regions for the three-span contin-uous beam and that the location of
