Seminar on the topic "Calculation of panel buildings in LIRA-CAD 2015"

In the period from 01 to 12 February 2016, a seminar was held on the topic "Calculation of panel buildings in LIRA-CAD 2015" for employees of RSE "Gosexpertiza". The seminar is intended for experts of the enterprise, incl. its branches, and was conducted in two stages in the cities of Almaty and Astana. During the seminar the following issues were considered: 1) existing modeling methods and literature; 2) general guidelines for the calculation of large-panel buildings; 3) elements of large-panel buildings and their calculation (types of joints, assessment of the compliance of horizontal joints, an example of calculating the compliance of the platform joint, an assessment of the compliance of vertical joints, an example of calculating the compliance of the embedded part, the strength of horizontal joints, an example of calculating the strength of the platform joint, the strength of vertical joints, strength of platform joints, checking the strength of wall panels, features of selection of reinforcement of wall panels taking into account longitudinal bending); 4) models of large-panel buildings (model of "equivalent columns", model of platform junction using KE55, model of platform junction using plate-like CE, comparison of three modeling methods using the example of a flat wall, simulation of discrete links and their groups (parallel and serial connection), accounting stage of construction in the calculation); 5) assembly of the building scheme in SAPPHIRE preprocessor (familiarity with the SAPPHIRE preprocessor, features of modeling of panel buildings in SAPPHIRE (setting properties of elements and the scheme as a whole), creating a physical model of walls, adjusting the physical model of walls using the "Editable analytics" mode, creating a physical model platform joints, creating a physical model of discrete links, creating a physical model of slabs, creating assembly stages, creating an analytical model, creating a model model); 6) correction of the circuit and its calculation in the PC LIRA-CAD (assignment / correction of the stiffness characteristics of the elements of the platform joint and elements of discrete links; setting data of the pulsating wind load; creating / adjusting the DCS / PCN tables; setting / correcting the data for the strength calculation; and analysis of VAT, testing the strength of platform joints, strength calculation of elements - selection of reinforcement, verification of the obtained reinforcement of walls taking into account the effect of longitudinal bending). The seminar was conducted by the specialist of the company "Lira Service" (Moscow). At the end of the seminar, the participants of the seminar were given a certificate from the company Lira Service.
