Investigation of strength and performance evaluation of hybrid wide flange (WF) beam-to-box column connections with inner diaphragms

In modern structural engineering, the connection between beams and columns plays a critical role in determining the overall performance and safety of steel structures and using an inner diaphragm is to improve strength and load transfer from beam to column too. This connection of WF beam to box column with inner diaphragm is responsible for transferring loads such as bending moments, shear forces, and axial forces between the members. The study of hybrid wide flange beam to box column connections with inner diaphragms has attracted increasing attention because of their superior load-carrying capacity, ductility, and ease of fabrication in high-rise and seismic-resistant structures. We usually use this ideal for high-rise buildings, bridges, and industrial facilities to create strong, load-bearing frames and seismic-resistant structures as well. In this study, the analytical assessment of mechanical behavior such as failure modes of the connection, evaluate the strength, load-displacement and the parametric effect of diaphragm properties by using numerical simulation software called ABAQUS/CAD. The finite element analysis results showed that variations in diaphragm parameters had only a minor effect on the overall load capacity and strength. It has showed us that parametric study is very important to improve strength and failure mode of connection.
