【摘要】 本文提出单向矩形正交异性板(同性板为特例)的实用计算方法。支承条件可以为两边简支、连续或不对称支承而其它两对边则可为滑支或自由。得出集中荷载作用点或矩形均布荷载中心所在的横截面上弯矩的实用计算公式。论证了这些公式的适用范围和精度,并与级数解或有限元法的计算结果作了充分的比较和验证。更多还原

【Abstract】 A practical method for computing the one-way rectangular orthotropic plates(isotropic plate as a special case)is suggested in this paper.The supported conditions in two opposite edges may be simply supported,continu- ous or supported nonsymmetrically and the other two opposite edges are slide- supported or free.A series of simplified formulas are given for calculating the bending moments along the cross section in which the acting point of the concentrated load or the center of a rectangular uniform load is located.The valid range and accuracy of these formulas were studied and the approximate results were examined and compared extensively with those by the triangular series solution or finite element method.更多还原
