林元培、张迺华同志著文提出的计算方法(以下简称林文)使装配式横向铰接桥板桔构的计算更趋合理,但不足之处是不能得出铰接处确定的切力值。本人认为,产生这个缺点不单纯是由于采用了“直线假定”,而是由于在“直线假定”的条件下仍然采用板的理论来分析切力的结果。对于宽跨比足够小的构件来说,“直线限定”对构件横向挠度的数值影响不大,但是对于横向挠度曲线的导数却有了本质上的歪曲。因此,以挠度曲线的导数来表
The calculation method proposed by Lin Yuanpei and Zhang Yuhua in the paper (hereinafter referred to as Lin Wen) makes the calculation of the orange structure of the assembled transverse articulated bridge plate more reasonable, but the disadvantage is that the shear force value determined at the hinge joint cannot be obtained. I believe that this shortcoming is not simply due to the “straight line hypothesis,” but rather to the analysis of the results of the shear force using the plate theory under the “straight line hypothesis.” For a member with a sufficiently low width-to-span ratio, the “linear definition” has little effect on the transverse deflection of the member, but the derivative of the transverse deflection curve is essentially distorted. Therefore, the table is represented by the derivative of the deflection curve
