Summary
THE STATICS OF FLAT GRIDWORK SYSTEMS
The subject of this paper is the application of the deformation
method, widely used in the statics of flat frames, for frame systems
loaded with forces perpendicular to the plane of the frame or with
moments, whose vectors lie in the plane of the system. Systems of this
kind are called flat gridwork systems.
These systems are applied extensively in reinforced concrete structures
such as broken line girders, annular beams, flat frames loaded by forces
caused by the wind, etc.
In the first section a general method of solution is given, while the
second section deals with the formulae of general transformation for
curved and broken line bars.
In the following sections the canonical equation of the above method
is expanded. This is then reduced to more specialized forms which are
typical for building technique.
Finally, in the last section, the deformation methods are extended to
include gridwork systems resting on an elastic foundation.
