六、装配式予應力實腹鋼梁用作剛架横梁1. 鉸接剛架在鉸接刚架中,横梁也可采用裝配式予应力梁。由于横梁鉸接于柱,水平荷载对横梁的受弯工作无影響,因而裝配式予应力梁的計算原理和構造方法和以上各節所述的情况相同。在这种梁柱鉸接的剛架中,裝配式予应力横梁以采用拱式更为经济,如圖19所示。 Sixth, prefabricated pre-stressed steel belly frame used as rigid frame beams 1. Articulated rigid frame in the articulated frame, the beam can also be prefabricated prestressed beams. Because the beam is hinged to the column, the horizontal load has no effect on the flexural behavior of the beam, so the principle and construction of the prefabricated prestressed beam are the same as those described in the previous sections. In such a beam-column articulated frame, the prefabricated prestressed beams are more economical to employ an arch, as shown in FIG. 19.
