description: The object of study is a floor slab with prestressing reinforcement ropes. The purpose of the work is to develop a post-tension modeling method for PC LIRA SAPR. Research objectives: - to develop a method for modeling post-tension in the LIRA SAPR software; - calculate the post-tension floor slab of a high-rise building using the method of modeling reinforcing ropes; - calculate the post-tension floor slab using the Linâs method; - compare the results. During the work, a high-rise office building was designed with a floor span of up to 13.5 m. To reduce the deflections of the slabs, a system of tension ropes was used. The effect of post-tension was taken into account in two ways. In the first case, the rope reinforcement was modeled in the LIRA SAPR software. In the second case, the force of post-tension was set according to the Linâs model as an external load on the slab. The discrepancy between the results regarding maximum deflections was 3.33%. In terms of internal efforts - from 0.54% to 1.12%. The results of the work will help simplify the introduction of post-tensioning technology into engineering practice in Russia and, in particular, in St. Petersburg. To achieve the set objectives, the following software systems were used in the work: Autodesk Revit 2022; Lumion 10; LIRA-SAPR 2022, SAPFIR-3D 2022 R1, SCAD Office 21.1.9.7; MS Project 2016; Bentley Synchro 4D Pro; Dynamo; Sigma PB; NormCAD.
