A hybrid pier made of Ultra High Performance Cementitious Composites (UHPCC) permanent form is proposed here. Uniaxial compression strength was analyzed theoretically. Circumferential cracking state is controlled and the loading capacity is derived. Ultimate strength of the hybrid pier is also derived theoretically. To verify the theoretical formula, numerical simulations were carried out. Short hybrid columns were tested to verify the numerical model. Comparison results show that the theoretical model predictions agree well with the numerical results and the hybrid effect is significant and cannot be ignored. The minimal wall thickness of UHPCC tube is proposed. Safety coefficients were proposed based on traditional structural design methods.
