Of special interest is the modeling and analysis of structures, designed for objective reasons without the use of software systems, but in the meantime, presenting the historical and cultural value. The cantilever Forth Rail Bridge built from 1882 till 1890 across the bay Firth of Forth is precisely this object.<\/p>\n<p style=\"text-align: justify;\">The purpose of this article is to analyze the stress-strain state of the Forth Rail Bridge on the finite-element model created using the Scad Office software system.<\/p>\n<p style=\"text-align: justify;\">The following tasks were set and implemented to achieve the desired results:<br \/>\n1. to create a calculated finite-element model with the appropriate stiffness characteristics, bonds and loadings;<br \/>\n2. to calculate and get the stress-strain state of the computational model;<br \/>\n3. to compare the obtained results with the current regulations and to assess compliance of designs being studied with the modern standards.<\/p>\n<p style=\"text-align: justify;\">This example of calculation of the Forth Rail Bridge construction in the Scad Office software system confirms that the application of software programs is indispensable when analyzing the existing buildings and structures and reconstructing them in future. The obtained results clearly illustrate the &#171;weak spots&#187; or, on the contrary, reveal a safety margin in the elements, which allow to minimize the economic costs when reconstructing historical objects.<\/p>\n<p style=\"text-align: justify;\"><strong>Keywords:<\/strong> railway bridge; cantilever; finite-element method; a Scad Office software system; stress- strain state; stiffness; 3D model; load; wind forcing; piers<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Semenov Aleksandr Aleksandrovich Ufa state petroleum technological university, Russia, Ufa E-mail: asfugntu@yandex.ru Poryvaev Ilya Arkadievich Ufa state petroleum technological university, Russia, Ufa E-mail: iporivaev@gmail.com Akhmetdinova Gulnara Rishatovna Ufa state petroleum technological university, Russia, Ufa E-mail: g.ahmetdinova@mail.ru Abstract.
