<![CDATA[This research aims to analyse the differences in the properties and stress distribution of steel connections of the Splice Plate and End Plate types using finite element method. Connection are crucial structural element that influence the overall strength, stiffness and behaviour of steel structure, particularly in beam splices where failure modes under flexural and shear loads can vary significantly. The experiment was carried out to determine the more efficient connection type evaluat the stiffness variation based on connection location, and identify failure point under combined flexural and shear forces. The analysis was performed with literature review and testing using MIDAS FEA NX software with a non-linear approach on SS400 grade steel and A325 bolts. The connection design referred to SNI and AISC regulations, analyzing I-beam profiles (IWF) and both connection types. The modeling was performed at two positions: mid-span and beam edge (end-span). The analysis results showed a similar Load-Displacement curve pattern with a maximum load of approximately 200 kN before entering the plastic phase, leading to a deflection of 435–448 mm at the mid-span. Although both connections are nearly identical behavior, the Splice Plate connection demonstrated higher stiffness, while the End Plate connection seemed more efficient because it requires fewer bolts and less additional plating in the fabrication process.]]>
