An Experimental Study on Ultimate Strength of High-Tension Bolted Connections in Cold-Formed Steel : Focused on the Shape of Bolt Holes |
Abstract |
The structural behavior of cold-formed steel construction connected with bolts is somewhat different from that of heavy Hot-Rolled Steel construction. The main cause of the difference is the thinness of the cconnected parts. The dominant type of failure modes in the cold-formed steel connected with bolts are longitudinal shear failure, bearing failure, tensile failure and shear failure. These types of failure modes are very important factors to decide the strength of the bolted cold-formed steel. Specimens are prepared by the diameter of high-strength bolts and bolt holes, e/d and the washer be used or not. Then, Analysis and compare the relationship of ultimate strength with those factors. The purpose of this study is, comparing with AISI or internal standard, to examine propriety of cold-formed steel design standards and to supply the basic data which is need to design the connected part by high-strength bolt. |
