Based on a number of calculations by computer and measurements of stresses in the reinforcements of box foundations in the field, the influence of the superstructure rigidity on the integral moment of box foundations are analyzed in this paper. The calculation methods of box foundations under frame structures and under shear wall structures are given separately. As to the box foundations under frame structures, a simplified calculation method with consideration of the influence of the superstructure rigidity by equivalent beam method is proposed and it is proved that it is sufficiently accurate. The equivalent beam formula given by G.G.Meyerhof in 1953 is examined and improved. It is recommended to use the improved equivalent beam formula to calculate the rigidity of rigid frame structure.

本文通过大量的计算和钢筋应力的实测,分析了上部结构刚度对箱形基础整体弯矩的影响,提出了上部为墙板式结构及上部为框架结构的箱形基础的计算方法。当上部为框架结构时,建议采用等代刚度梁的方法作为考虑上部结构共同作用的简化计算方法,该法经证明具有足够的精确度。对于G.G.Meyerhof在1953年建议的等代刚度梁公式,本文进行了验证和改进,建议按改进后的公式计算上部框架结构的等代刚度。

This paper points out that the first n natural frequencies of continuous beams or one-story rigid frames without sideway are always somewhat greater than the respective “simple-supported-beam fundamental frequency” of the corresponding structures respectirely. On this basis, this paper suggests an equivalent beam method for determining the natural frequencies of continuous beams and one-story rigid frames withot sideway. The equivalent beam is a simply supported single-span beam with elastic rotational constraints...

This paper points out that the first n natural frequencies of continuous beams or one-story rigid frames without sideway are always somewhat greater than the respective “simple-supported-beam fundamental frequency” of the corresponding structures respectirely. On this basis, this paper suggests an equivalent beam method for determining the natural frequencies of continuous beams and one-story rigid frames withot sideway. The equivalent beam is a simply supported single-span beam with elastic rotational constraints at its ends. The jth natural frequency of the structure under consideration is equal to the fundamental frequency of the jth equivalent beam. A unified expression is formulated for the evaluation of the fundamental fre-queney of the equivalent beam by the method of iteration. It is found that satisfactory results can be obtained generally by making 1 or 2 trials.

本文指出,连续梁或无侧移单层刚架的前n个固有频率,总是分别略大于其相应结构的对应"简支基频".利用这个性质,提出了用以计算连续梁或无侧移单层刚架的前n个固有频率的等效梁方法.等效梁是一个两端具有弹性转动约束的简支梁,第(j)个等效梁的基本频率,就是原结构的第j个固有频率.导出了用迭代法求等效梁的基本频率的统一公式.一般进行1-2次试算,可得出满意的结果.

The author proposes that the partially prestressed highway bridges be designed according to the degree of prestresing. In this paper, the design method and its merits are explained. The calculations for the projects in the "Standard Design Drawings JT/GQB 025-75" has been made. Based on this, the influence of the degree of prestressing upon the steel requirement and the relations between the degree of prestressing and the crack width have been analyzed. The crack control by hypothetical tensile stress is too conservative and unsuitable for lower degree of prestressing. Therefore, the recommendation for design of PRC bridges by means of hypothetical tensile stress is improper.

本文建议按预应力度设计预应力公路桥梁,对按预应力度设计预应力梁的方法作了介绍,指出了它的优点。文中按“公路桥涵标准图JT/GQB 025—75”的截面进行了计算,对预应力度对用钢量的影响以及与裂缝宽度的关系做了分析,得到用名义拉应力控制裂缝过分保守,不适用于低预应力度的情况,故不宜推荐作为设计部分预应力桥梁的基本方法的初步结论。
