Analytical and Experimental Investigation of I Beam-to-CFT Column Connections under Monotonic Loading (RESEARCH NOTE)

Authors

Abstract:

In this study, the behavior characteristics of I beam-to-concrete filled tube (CFT) column connection is studied through experiment and finite element models under the monotonic loading. To validate the finite element modeling, at first, an experimental model is made and experimented. After validation of the finite element modeling, different models were created in the software. The studied parameters include the endplate thickness and the connection type. Various types of endplate thickness are studied for bolted and weld connections. For bolted connections, different types of I beam-to-CFT column connections are studied by using the bolts passing and not passing through the CFT section. The Results show that increase in endplate thickness leads to increase in the connection flexural strength and stiffness and decrease in rotation in a specific resistance value.

Mathematical Modeling of Column-Base Connections under Monotonic Loading

Some considerable damage to steel structures during the Hyogo-ken Nanbu Earthquake occurred. Among them, many exposed-type column bases failed in several consistent patterns, such as brittle base plate fracture, excessive bolt elongation, unexpected early bolt failure, and inferior construction work, etc. The lessons from these phenomena led to the need for improved understanding of column base...

The Effects of Internal and External Stiffeners on Hysteretic Behavior of Steel Beam to CFT Column Connections

This study focuses on performance of H-shaped steel beams to CFT column rigid connections. To this end, the effects of internal and external stiffeners on hysteretic behavior of connections were studied. Comparative numerical analyses carried out on eight different connections. To this end finite element models were prepared using ANSYS and nonlinear cyclic analyses carried out. Results of this...
