Abstract
The end-plate connections are most often used as a connection of beam to column and between beams that perceive a moment. Taking into account the difference in the strength of the end plate and the strength of high-strength bolts, which will lead to three different types of failure mechanisms, it is necessary to study the strength and stiffness of such joints using the component method. The most important parameters in this method are the calculated width of the bearing elements for bending and the stiffness coefficient. Determining the ratio of the strength of the connection elements to the failure mechanism and calculating the stiffness coefficient calculated on the basis of the T-shaped element is an important task. For this reason, the objective of this paper is to develop a method for calculating the bending stiffness and strength of the end-plate connections joints under monotonic loads. The proposed calculation method is based on the component method, structural mechanics and strength of materials. Verification is performed on the basis of the experiments performed, for which practical dependencies between the moment and the angle of rotation can be obtained. The practical implementation of the proposed method is demonstrated by calculating the bearing capacity and rigidity of the sample of the experiments performed.
As results of the study, it is possible to highlight the method for calculating the rigidity of the end-plate connections of beam to column, the influence of the strength of different elements of such connections on the mechanism of destruction and a recommendation for designing connections under monotonous loads. Using the developed method, it is possible to accurately estimate the bearing capacity and rigidity of the connection, design a diagram of the relationship between the moment and the angle of rotation.
