本文在分析研究墙板等弯曲构件试验资料的基础上,对12米预应力混凝土多孔墙板的结构计算问题进行了探讨,提出了推荐计算方法。不当之处,请读者批评指正。 (一)正截面抗弯强度计算 (详见本刊1979年第2期“多孔墙板正截面抗弯强度计算方法探讨”一文)。 (二)斜截面抗剪强度计算上文中表2第15号窗下板,在标准荷载作用下竖向与横向剪力分别为Q_z=3.96吨,Q_y=1.77吨;17号窗间板Q_z=3.835吨,Q_y=2.423吨。多孔墙板斜
In this paper, based on the analysis of the experimental data of wall members and other bending members, the structural calculation of 12m prestressed concrete porous wallboard is discussed, and the recommended calculation method is proposed. Inappropriate, please readers criticized and corrected. (a) calculation of the normal section bending strength (see the article “Exploration of the Calculation Method of the Bending Strength of Perforated Wallboards for Perforated Wallboards”, Issue 2 of 1979). (II) Calculation of Shear Strength of Inclined Section In the window lower panel of Table 2 in Table 2 above, the vertical and lateral shear forces under the standard load are Q_z=3.96 tons, Q_y=1.77 tons, respectively; the No. 17 window panel Q_z= 3.835 tons, Q_y = 2.423 tons.
