本文介绍了连续双向板力矩分配法的一般原则及有关计算公式和系数表,并对公式给予证导和对系数表作了验算示例,由此指出斯氏书中有些公式在引用时未能纠正原著的排印错误,以及例题中在选取系数时的个别错误。同时还指出,该书中绘示的连续板跨中和支座弯矩图形的原则性错误,因这时扭矩对切开板带在承受分配的横向荷载下跨中弯矩的减小影响,较对简支板时小很多。这是与梁构件根本不同的,即这时支座弯矩平均值(绝对值)加跨中弯矩应大于简支板的跨中弯矩。
In this paper, the general principles of the two-way plate torque distribution method and the related calculation formulas and coefficient tables are introduced. The formula is given as a guide and the example of the coefficient table is verified. It is pointed out that some formulas in the book of Szeticus failed to be corrected The original typographical errors, as well as individual errors in the selection of coefficients in the example. At the same time, it is also pointed out that the principle chart of the bending moment of the continuous plate spanning mid-span and the bearing plate shown in this book is erroneous because of the influence of torque on the reduction of the mid-span moment under the lateral load subjected to the distributed lateral load. Much smaller than the simple support. This is fundamentally different from beam members, that is, the mean value of moment of abutment (absolute value) plus moment at mid-span should be greater than the moment at mid-span of simply supported plate.
