Experimental Study of Jumbo Size Reduced Beam Section Connections Using High-Strength Steel
Publication: Journal of Structural Engineering
Volume 130, Issue 4
Abstract
There is an increasing demand for jumbo sections and high-strength steel in the construction of modern high-rise buildings. However, there is a lack of knowledge of the behavior of this type of construction, especially under seismic loading. This paper describes experimental studies of reduced beam section connections using jumbo sections and high-strength steel. The steel selected is ASTM A572 Gr. 60 steel and the flange thickness of both steel beam and steel column is 50 mm. The beam flanges in the preselected area are tapered following the seismic moment demand. As a result of this arrangement, an enlarged plastic zone can be obtained in the preselected area and seismic energy can be dissipated through the yielding of steel plate in this region. The plastic rotational angle can be more than 0.03 radians. It is also found that the weld tabs of the complete joint penetration weld between beam flanges and column flanges have a crucial effect on the premature fracture of the connection and it is suggested that these weld tabs be removed.
