摘要
详细阐述了抗震设计对扁梁、柱截面尺寸的要求与限制,探讨了无粘结部分预应力混凝土扁梁控制截面抗震配筋,分析了无粘结部分预应力混凝土扁梁梁端的受力,改进了以往扁梁梁端扭矩设计值计算公式。
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.
