摘要
对梯形截面箱梁在偏载作用下发生的畸变进行了分析,并在此基础上导出了梯形截面箱梁畸变惯性矩的计算式,可用此方法计算其畸变应变能.
In this paper, the aberration of trapezoidal box girder is analysed according to the internal force equilibrium and deformation coordination of its box cross-section when unsymmetical load is applied to the girder. Based on these, the aberration inertia moment formula of trapezoidal box girder is developed, and the aberration strain energy is easily calculated.
