The present study aims at examining the behaviour of circular base plate connections under bending moment. An experimental program is developed and tests are performed on twelve pipe specimens with circular base plate and circular anchor bolt pattern. Pipe
diameter, base plate diameter, number of anchor bolts and bolt circle diameter are all kept constant throughout the experimental investigation. Base plate thickness and the presence of plate stiffeners are the varied parameters. The specimens are loaded till
failure under vertical tip load and failure mechanism is determined based on the observed deformed shape of the base plate. The results of the bending tests are presented in the paper. The presented experimental data will help in the development of
a design model for circular base plates.
