Exploring the Stiffness of Joint Beam Connections: A Literature Review

In the realm of construction engineering, connections between beams and columns, as well as between beams themselves, play a crucial role in ensuring the stability and safety of a structure. These connections are often reinforced with bolts and welding to enhance their rigidity. A good connection is one that is rigid, meaning it does not experience angular rotation under load. This study aims to delve into the analysis of the rigidity of joint beam connections by comparing the moments that occur in the connection with the moment of the beam capacity in elastic conditions. This is essential to guarantee safe construction and prevent potential damage.

The Importance of Connection Stiffness in Construction

Connection stiffness is a critical aspect of construction engineering, as it directly affects the overall stability and safety of a structure. A connection with high stiffness can withstand loads and moments without experiencing significant deformation, ensuring that the structure remains stable and secure. Conversely, a connection with low stiffness may lead to angular rotation, compromising the structural integrity of the building. Therefore, it is essential to analyze and optimize connection stiffness to ensure safe and stable construction.

This study employed the slope deflection method to calculate the degree of stiffness in the joint beam connection. The calculation results revealed that the percentage of stiffness reached 73.68%. By examining the permitted voltage (σijin = 1600 kg/cm²) and utilizing the IWF profile of 600 x 300 x 582 x 300, the connection was deemed rigid because θa = θb and safe profile. These findings indicate that the joint beam connection studied had a high level of stiffness, capable of withstanding loads and moments without compromising its structural integrity.

Meaning and Implications of the Results

The results of this analysis demonstrate that the combined beam connection studied had a fairly high level of stiffness. This indicates that the connection is able to withstand the load and moment that occurs well, making it a reliable choice for safe and stable construction.
