“…Дуже важливо вміти діагностувати реальну загальну поведінку з′єднань балки з колоною на основі їхніх геометричних і механічних властивостей. Цього можна досягти за допомогою «компонентного методу», запропонованого в роботах [1][2][3][4][5][6][7][8][9], і на якому базуються норми проектування сталевих конструкцій ЕС3 [10]. Як слушно зазначають автори [11,12], це питання насьогодні є досить актуальним.…”

End plated connections of metal structures are quite relevant and are usually used in office, commercial, and commercial-office buildings. It is very important to be able to diagnose the real general behavior of beam-to-column connections based on their geometric and mechanical properties. Therefore, the analysis of steel structures at the modern level requires a specialist to have a thorough understanding of their work, as well as the calculation provisions laid down in current design codes. In contrast to Eurocode 3 design codes, the current Ukrainian state building regulations do not contain clear instructions on the beam to column joint calculation and do not even give a clear definition of the concept of steel joint and steel connection. It should be noted that the beam to column connection is the most responsible area that requires special attention, as it significantly affects the design scheme of the structure, as well as its economic efficiency. By using the semi-rigid connection concept, weight savings of up to 20% can be achieved. In the presented article, a simplified mathematical model of the t-stub component of the tensile zone of the semi-rigid bolted connection of the beam to the column was developed using the component method. In the given solution of the connection in the tension zone, the following components were distinguished: the flange in bending, the end of the column in bending, and the bolts in tension. All these elements were modeled from two t- stub components connected through an end plate with the help of bolts. A design scheme for determining the stress-strain state was proposed. The analysis of the exhaustion of the bearing capacity of the t- stub component was performed according to three scenarios depending on the size of its individual elements (end plate thickness, bolt diameter). The obtained results will make it possible to determine the bearing capacity with possible variations of the transition to the limit state, as well as to estimate the deformations of the considered component of the connection. Keywords: end-plate connection, mathematical model, T-stub component, bolt connection.

During the Northridge earthquake, extensive brittle failures on the weld zones of the beam bottom flanges in the rigidity connection of steel special moment frames (SMFs) were detected. One of the primary reasons is the high-tensile strain demand created at the beam bottom flange zones due to positive bending. The weak panel zone of the I-section column exhibits more shear deformation, which promotes and accelerates the brittle fracture of the beam bottom flange weld zones. A box-strengthened panel zone can minimize the shear deformation of the panel zone of the I-section column, which may also reduce the inter-story displacement of steel SMFs and enhance their seismic behavior. In order to investigate this fact, in this research we carried out a model test of a steel frame with a box-strengthened panel zone to examine SMFs’ seismic performance and inter-story displacement, as well as testing the contribution of panel zone shear deformation to inter-story drift. Numerical methods were then used to investigate the influence of the axial compression ratio and beam-to-column linear stiffness ratio on the effect of shear deformation on the box-strengthened panel zone. Design recommendations are given based on the research results.
