The influence of torsion on the behavior of floor slab structures is examined using the results of tests of typical multi-panel and isolated half-panel slab structures supported on spandrel beams at the edges. Of particular interest is the transfer of exterior negative moment from the slab to the columns through the spandrel beams at service loads and at failure. The test results provide a means of estimating the importance of torsion in floor slab structures and of evaluating the applicability of proposed design procedures for torsion to spandrel beams.

An attempt has been made in this paper to analyse a fixed ended circular staircase with an intermediate landing by the flexibility method.

When a reinforced concrete structure cracks the ratio of torsional to flexural stiffness of its members will drop. The resulting redistribution of torsion and bending moments is the subject of this paper.
In building floors, when a beam frames into a girder, serious torsional stresses may develop in the girder. The magnitude and distribution of the slab moment is greatly influenced by this torque.

Cellular concrete bridge decks have desirable aesthetic properties and because of their high torsional stiffness a good strength/weight ratio. Current analytical methods tend to use three dimensional models which are restricted in scope and are expensive.
