Abstract

Данная работа посвящена изучению влияния учета податливости стыковых соединений в сборных железобетонных конструкциях, а именно в крупнопанельных зданиях. Целью работы является выявление расхождения значений расчетных величин податливости в зависимости от метода расчета и анализ их влияния на напряженно-деформированное состояние конструктивных схем.Задачи, которые решались в ходе исследования: 1. Изучение существующих методик расчета податливости стыковых соединений; 2. Создание корректной модели с учетом податливости узлов; 3. Анализ полученных результатов расчетных конструктивных схем. Работа проведена на основании предоставленных компанией Bonava документов, включающих в себя планы подвального, первого и типового этажей, и существующую нормативную документацию, учтенную при построении моделей и анализе полученных данных. Использованы программные комплексы САПФИР2020, Лира-САПР2020, AutoCAD 2020 для моделирования объемно-планировочных и конструктивных решений. В результате произведен анализ факторов, влияющих на податливость стыковых соединений крупнопанельных зданий, рассмотрена работа стыков в конструкции, а также приведено сравнение напряженно-деформированного состояния расчетных моделей здания с учетом и без учета податливости стыков.

The topic of the final qualification work: «Introduction of the connection joints’ pliability in precast concrete elements». This work is devoted to research the influence of the pliability of connection joints in precast concrete elements, namely in large-panel buildings. The aim of the work is to identify the discrepancy between the values of the pliability values depending on the calculation method and to analyze their influence on the stress-strain state of structural schemes.Tasks that were solved during the study: 1. Review of existing methods for calculating the pliability of panels’ joints; 2. Creation of a correct model considering the of the connection joints’ pliability; 3. Analysis of the obtained results of structural design models.The work was carried out on the basis of documents submitted by Bonava, including plans for the basement, first and standard floors, and existing regulatory documentation, which considering in building of structural design models and analyzing the data obtained. The software systems SAPHIR 2020, Lira-CAD 2020, and AutoCAD 2020 were used to model space-planning and design solutions.As a result, was made an analysis of the factors affecting the pliability of of the connection joints in large-panel buildings, the operation of joints in a structure was considered, and a comparison of the stress-strain state of structural design models of a building was made with and without allowance for panels’ joint pliability.
