The authors, using the finite element method, analyse the rules of continuous deep beam internal forces under the influence of the support plate width. Meanwhile they study transmission force features that the live load is applied on each support cross-section, and present rational simplified computation model. Also they draw up internal force calculation tables of 2- 5 equal span, different span-depth ratio and every cross-section in continuous deep beams under the action of the live load. The tables...

The authors, using the finite element method, analyse the rules of continuous deep beam internal forces under the influence of the support plate width. Meanwhile they study transmission force features that the live load is applied on each support cross-section, and present rational simplified computation model. Also they draw up internal force calculation tables of 2- 5 equal span, different span-depth ratio and every cross-section in continuous deep beams under the action of the live load. The tables can be used by designers.

作者以有限元法分析了连续深梁的内力受支座垫板宽度影响的变化规律;分析了活荷载作用在各支座截面的传力特性,并提出了合理的简化计算模型。编制了2—5等跨的不同跨高比的连续深梁在活荷载作用下各截面的内力计算表格,供设计人员使用。

A lifting surface method for predicting hydrodynamic characteristics of a hydrofoil moving beneath the free water surface has been developed. Swept horseshoe vortex sheets of equal span are distributed chordwise toreplace the swept and tapered hydrofoil. The unknown circulation distribution of each bound vortex is denoted by a sine series. It is found thatthe calculation agrees well with experimental results.

本文在文献的基础上,进一步提出预测后掠水翼水动力性能的升力面计算方法。该方法的特点是用沿翼弦离散布置的一组展向涡线来模拟水翼,而在水翼的展向,每根涡线上的涡量采用连续分布,并在计算中将其展开为正弦级数。计算示例表明,本方法计算时间省,精度高,对预测水翼的升力和诱导阻力有实用价值。

In this paper, a wide and shallow curved plate bridge with multicell section has been transformed equivalently into a straight bridge with equal span length and unequal rigidity, then formulas for simplified analysis of transverse load distribution for this equivalent bridge are derived based on the principle of a hinge-jolnted plate method. The calculated results and the results from loading test of a perspex model bridge and that from formulas referred to in the reference [1] accord well.

本文将宽矮多格室曲线板桥化为跨长相等而刚度不等的等效直线板桥,然后按铰接板法的一般原理导得其荷载横向分布的简化公式,并通过有机玻璃模型试验和文献[1]的理论公式进行了验证,三者基本符合。
