Use of grooved clamping plate to increase strength of bolted moment connection on cold formed steel structures

The purpose of this study was to look at an alternative way of enlarging the strength of the moment connection on cold formed steel structures using the grooved clamping plate. To support the research we use the experimental method of testing the moment connection on the cold formed steel with the addition of grooved clamping plate. Experimental results show that the cold formed steel moment connection using the grooved clamping plate can be significantly increased compared to a cold formed steel moment connection that only increases the diameter of the bolt and the distance between the bolts. From these results, it is known that the addition of the grooved clamping plate at moment connection can give a nominal moment force increase of almost 200%, whereas the addition of bolt spacing and diameter gives only a nominal moment force increase of almost 50%. Of course, this experimental result will be an alternative innovation in terms of enlarging the strength of the moment connection on cold formed steel. (paper)
