The construction industry in Indonesia is experiencing rapid development, encouraging the emergence of innovations in construction design. One such innovation is the utilization of hollow concrete pier and high strength reinforcement bar (Gr. 80 or yield strength of 550 MPa). The use of a hollow concrete pier and high strength reinforcement bar will reduce the cement and steel consumption leading to reduced emission of CO2. In addition, these hollow piers aim to reduce the dead weight of a structure, mitigating the inertia experienced during earthquakes. As a result, this reduces foundation dimensions, leading to significant cost savings in construction. This paper shows that the seismic behavior of a hollow pier is comparable to that of a solid pier in terms of strength, energy dissipation and ductility. Hence, it has the potential to be widely used in industry.
