Experimental Study on Horizontal Oblique Beam-End Connections
https://orcid.org/http://orcid.org/0000-0002-9645-7851
Connections consisting of wide flange beams and square hollow section (SHS) columns with through diaphragms are commonly used in steel moment frame in Japan. Generally, it is desirable to design the beam-to-column connections so that the column and the beam are perpendicular to each other. In some cases, columns and beams are connected diagonally to gain larger space. However, the effect of such oblique beam-end connections on structural behavior remains unknown. To investigate the effect of oblique angles, the full-scale cyclic loading tests were carried out. Based on the experimental investigation, the fundamental structural behavior, plastic deformation capacity, and strain distribution at the flange of the beam-end connections considering oblique angles were discussed in this paper. The test results indicated that (i) there is no significant effect of oblique angles on the fundamental structural behavior; (ii) the effect of the different oblique angles on the deformation capacity is not affected by the cyclic loading after local buckling; (iii) the plastic deformation capacity and strain distribution of the beam end is greatly affected by the oblique angles of 30° or larger. Also, it is indicated that a large oblique angle tends to change the failure mode of the thicker beam flange.
