Abstract

A statically determinate structure is defined as one in which the unknown quantities do not exceed the number of independent equations of static equilibrium that can be written for the structure. A  statically indeterminate structure is one in which the number of unknown reactions exceed the number of equations  of static equilibrium. Structures, continuous or statically indeterminate, are found in  certain types of trusses, arches, rigid frames, fixed-end beams and propped cantilevers. The continuous structure, either in beams or slabs, is quite common  in building construction. Many ingenious   methods of construction have been evolved to take advantage of continuity-the mushroom slab, the continuous waffle slab and most successful of all, the prestressed flat plate.
