Abstract:
The most commonly used moment resisting connections are bolted end plate beam to
column connections. Connections are usually designed as simple or continuous
although the actual behavior is known to fall between these two extreme cases. The
use of semi- continuous connection results substantial savings in steel weight of the
overall construction. Extended endplate, Flush end plate and partial depth
connections are the widely used type of connections in steel frame construction. To
understand the real behavior of semi- continuous connection, full scale laboratory
test is the most accurate approach, but it is time consuming and costly to undertake.
Therefore other methods were developed to predict the capacity of connections.
Thus, in this study 48 extended end plate and 48 flush end plate connections are
analyzed to find the connection’s behavior with variations in bolt diameter, end plate
thickness, and grade (4.6/8.8) and bolt gauge length. A method proposed by Steel
Construction Institute (SCI) is taken into account for analyzing. The analyzed
connections are classified based on strength and stiffness.
