| Abstract: | The requirement and restriction for the size of flat-beam/column and sections in aseismic reinforced design are discussed. Section aseismic reinforcement for unbonded prestressed-concrete flatbeam frame structure is studied, and mechanic forces acting on the terminal section of the beam/column are analyzed. The calculated formulation of the torsion in the terminal section of prestressed concrete flatbeam is improved by internal forces analysis. |
