Increase connection resistance with 4 bolts in a row joint configurations
Bolted end-plate moment connections are widely used in steel structures. The most common joint arrangement has two bolts in each row
and when the beam is deep, the moment capacity of the joint can be increased by adding additional bolt rows. However additional bolt rows add little to the resistance of the whole joint thanks to their reduced associated lever arm.
But what can we do if we require greater resistance and the lower bolt rows are not providing enough additional capacity?
If construction permits, the End-plate can be extended above and below the beam flanges to give you a larger lever arm.
When this is not enough, then in the case of wide flange beams, such as UC or HE European sections, you can use four bolts in a row.
With MasterSeries Connection Design, you can design moment end-plate connections with different configurations of four bolts in a row. You can have 4-bolts per row in every row, or you can have 4-bolts in the external rows only.
Connection design can be done based on the regulations of the Eurocode or British Standard.
