Разработана комплексная методика экспериментального исследования узлового соединения железобетонных рам при статико-динамическом нагружении. В качестве объекта исследования выбрана крестообразная модель узла рамного каркаса многоэтажного здания. Для испытаний предложено использовать специально разработанную нестандартную установку копрового типа, интегрированную в гидравлическую систему, которая позволяет моделировать как статические, так и динамические воздействия. Экспериментальными исследованиями, с использованием современных измерительных систем, включая тензометрические розетки и высокоскоростную видеосъемку цифровой видеокамерой, получены деформации бетона и арматуры, параметры трещинообразования и разрушения для опытных конструкций узлов рам. Полученные экспериментальные данные о статическом и динамическом сопротивлении узла железобетонной рамы позволят верифицировать создаваемые расчетные модели железобетонных конструкций рамных каркасов зданий.

A comprehensive methodology for experimental research of nodal connections under static-dynamic loading has been developed. A cruciform model of a frame joint in a multi-story building was chosen as the design scheme. For testing, it is proposed to use a specially developed non-standard drop-weight type setup, integrated into a hydraulic system. This system allows for the simulation of both service and emergency impacts, including the additional dynamic loading of the joint under special conditions. The experimental studies yielded data on concrete and reinforcement deformations, crack formation parameters, and failure characteristics for the prototype frame joints. This was achieved using modern measurement systems, including strain gauge rosettes and high-speed video recording. The obtained experimental data on the static and dynamic resistance of the frame system joints will allow for the verification of analytical models, enhance the current understanding of the behavior of joints made from a new type of concrete, and validate both improved and newly developed analytical models for reinforced concrete building frames.
