一、畸变量W和γ的关系目前,国内外对单室(梯形或矩形)箱梁畸变所发表的文献较多,但主要为两类。一种是用扭转荷载点处的挠度W表示截面的畸变量(图La);另一种是用两相邻边的畸变角表示畸变量(图1b)。两者均能得出与弹性 First, the relationship between the amount of distortion W and γ At present, the domestic and foreign literature on the single chamber (trapezoidal or rectangular) box beam distortion published more, but mainly two categories. One is to use the deflection W at the torsion load point to represent the amount of distortion in the cross section (Figure La) and the other to use the distortion angle of two adjacent edges to represent the amount of distortion (Figure 1b). Both can be drawn and flexible
