Tbilisi: Zakgosizdat, 1934. Item #1895

42 pp. 20.2x14.1 cm. In original illustrated publisher’s wrappers. Loss of the pieces of the spine, tears to the wrappers, rubbed. Otherwise in good condition.

Scarce. First edition. 1 of 1,000 copies. Edited by Professor K. Zavriev. One of the first Soviet works on the theory of calculating bridge vaults.
This rare publication devoted to the theory of calculating bridge vaults was written by the Honored Worker of Science and Technology of the Armenian SSR and the Director of the Institute of Geophysics and Engineering Seismology of the Academy of Sciences of the Armenian SSR Armen Nazarov (1908-1983) in 1934. At the time, the issue of calculating arched bridges for the action of lateral horizontal forces (wind, seismic forces) was poorly studied and the book served as one of the first works on the subject matter. The edition, which was based on the examination conducted by the author at the Transcaucasian Institute of Structures (ZIS), consists of two main sections: The Theory of Spatial Bending of Curved Bars and On the Resistance of Arched Bridges to Lateral Loading. In the book, the author elaborates upon such topics as differential equilibrium equations, relationship between deformations and internal forces and deformation equations, etc. Nazarov analyzes the study of Professor V. Gastev Raschet svodov na deystviye gorizontal’nikh nagruzok [i.e. Calculating Vaults on the Activity of Horizontal Forces], which was published a few months prior to the present edition and proves the falseness of Gastev’s assumption that “The method of calculating vaults for the action of horizontal loads adopted in the current technical conditions does not at all correspond to the actual operation of the vaults under these conditions.” Importantly, after checking Gastev’s study and correcting the error in the Professor’s formula, Nazarov shows that the conditional method of calculation, even for elevated vaults, for which the discrepancies should be especially large, gives deviations not exceeding 20%.
Armen Nazarov is the author of numerous works on mathematical methods in mechanics, applied mechanics and operational calculus, structural mechanics, applied mathematics, engineering seismology, and seismic resistance of structures.
Overall, one of the first thorough studies of the theory of calculating bridge vaults.
