In order to study the performance of the connections between lightweight aggregate concrete filled circular steel tube beam and reinforced concrete pier

three types of connections are designed in this paper

including piercing reinforcing bar

piercing reinforcing bar with moment transfer plate and piercing I-beam. The energy consumption of these three kinds of connections under low frequency cyclic loading is studied by pseudo-static testing.The results indicate that all the connections have good energy consumption behaviour

the equivalent viscous damping coefficient is higher than the requirement of reinforced concrete structures

and the ductility coefficient is larger than 2

which is required by China seismic code.After the connections yield

these three kinds of connections still have remarkable bearing capacity.The equivalent viscous damping coefficients and the ductility coefficient are almost the same for piercing reinforcing bar and piercing I-beam.But the piercing reinforcing bar with moment transfer plate is smaller than the other two.
