| Abstract: | Tha experimental results of two 1:3 scale models of high efficient prestreued concrete(HPC) composite frames and the comparative analysis with RC comparative analysis having the same load-bearing capacity are reported in this paper. The mechanic behavior of HPC coposite frarnes, their strain and deformation properties, and the coefficient of two-stage loadinog are ana- lyzed. Besides, the ooncept of integral effective coefficient a of internal forces in sections of pre- fabricated oomponents is also presented. |
