Arch designs demanded by the time in building sciences and architecture
Incoming article date: 09.03.2016The article presents a review of recent projects of arch designs, work on their research. Arch structures are widely used in construction since ancient times. The Romans were the first to use the arch of considerable size, and some of them survived until our days. One of the examples of arch structures in Roman architecture is the Roman aqueduct of Pont du Gard. Accident arched constructions mostly occur due to buckling of the entire structure. Risk of accident from loss of stability is especially great because buckling can occur suddenly. The loss of stability as possible out of plane and in plane. Flat design farm, arches, frame resistance to bending in the plane of the structures than from the plane. Cases of accidents of industrial and civil constructions, which occurred from buckling lateral torsional buckling is little known. Buckling lateral torsional buckling of structures, working in transverse bending, is given little attention, as it is believed that if and has in some cases place, it would not lead to accident due to their shared relationship of beams with other designs.
