摘要 针对工程上常用的带有梯形悬臂板的双室箱形截面,基于薄壁箱梁约束扭转理论,推导给出了其扭心显式公式,数值算例验证了所推导公式的正确性。以所推导的显式公式为基础,结合数值算例,分析了梯形悬臂板端部和根部厚度变化对箱形截面扭心位置的影响。研究结果表明,梯形悬臂板端部厚度不变时,其根部厚度变化对箱形截面扭心位置几乎不影响。 Based on the constrained torsion theory of thin-walled box girder,an explicit formula for the torsion center is derived for the two-chamber box section with trapezoidal cantilever plate commonly used in engineering,and the correctness of the derived formula is verified by numerical examples.Based on the derived explicit formula and numerical example,the influence of the thickness of the end and root of trapezoid cantileverplate on the torsional center of box section is analyzed.The results show that when the end thickness of trapezoidal cantilever plate is constant,the change of the root thickness has little effect on the position of torsional center of box section.
