Innovation of material and function represents the direction of contemporary architecture template development. Based on the study results of domestic and foreign building templates, a new type of template structure—Steel fiber RPC (reactive powder concrete) column-template without demolition is presented taking account of the characteristics of template materials and construction methods. Compared with the traditional template, the new one takes composite material and function innovation as a breakthrough. It improves efficiency of construction while the column-template forms the outer surface of the decorative grass-roots which expands the scale of the function of column template. This paper introduces the material selection and illustrates the calculation of the new template. Based on the existing design specification of template, new design recommendation of template thickness is proposed through theoretical analysis and simulation, which provides a theoretical basis of steel fiber RPC column template without demolition in engineering applications.
