对于钢及混凝土单室与复室箱形梁的变形性能,是参照了那些具有不同的壁厚、荷载长度、加劲杆件的尺寸、横隔板间距、截面形状、曲率及支座位置等的特定例子来进行研究的。 研究了对称与反对称的荷载分量的意义,注意到当支座为斜交时,当桥在曲线上时,当为复室截面时,则即使在对称荷载作用之下也将发生畸变应力。说明了设置抵抗截面变形,尤其是钢箱变形的适当的约束措施的重要性。
For the deformation behavior of steel and concrete single-chamber and double-chamber box girders, reference is made to those with different wall thicknesses, load lengths, stiffener dimensions, diaphragm spacings, cross-sectional shapes, curvatures and bearing positions Specific examples for research. The meaning of symmetrical and antisymmetric load components is studied. It is noted that when the support is skewed, distortion occurs when the bridge is on a curve and when it is a double chamber section, even under symmetrical loads. The importance of setting appropriate restraining measures against the deformation of the section, in particular the deformation of the steel box, is illustrated.
