Precast segmental columns are attracting more and more interests in the construction industry due to its many advantages such as minimized on-site construction activities, improved construction quality, and reduced residual displacement after a severe earthquake. In previous studies, precast segmental columns were normally constructed with ordinary Portland cement concrete (OPC) together with steel tendons and rebars. It is well known that the production of OPC significantly contributes to the carbon dioxide emission, and steel is vulnerable to corrosion. It will be ideal if other green and sustainable construction materials can be applied to replace the conventional OPC and steel tendons and rebars. Geopolymer concrete (GPC) which uses industry wastes as binders has been developed as an alternative to the ordinary OPC, and the corrosion resistant Fibre Reinforced Polymer (FRP) can potentially be used to replace the steel tendons and rebars. In this study, GPC and basalt fibre reinforced polymer (BFRP) tendons and rebars are used to construct segmental columns, and the seismic performances of the newly proposed segmental columns are examined through shake table tests. Both uniaxial and biaxial ground motions were used as inputs to investigate the effect of the biaxial excitations on the seismic performance of the columns. The test results indicated that the BFRP reinforced GPC segmental column with BFRP tendon had comparable seismic performance to the steel reinforced OPC segmental column with steel tendon under low levels of earthquake excitations, but it failed slightly earlier due to that the BFRP tendon has lower elastic modulus than steel tendon.
