Abstract

Using the assumption that the load is evenly distributed in the horizontal direction, the article has given the cable deflection equation as a function that depends only on the horizontal coordinates, the length of the cable and horizontal distance between two supports. This result leads to the construction of a general system of equations to calculate the deflection, tension, and elongation of an elastic single cable resting on two supports with or without high difference, bearing uniformly distributed loads (or evenly distributed at intervals) and load is concentrated at many points. Calculations of examples to compare with results have been performed by other methods.

弹性抛物线索在各段均布荷载和多点集中荷载作用下的计算方法

本文在假定荷载在水平方向上均匀分布的前提下，给出了索挠度方程，该方程仅与水平坐标、索长度和两个支座之间的水平距离有关。这一结果导致了一个通用方程组的构建，以计算弹性单索的挠度、张力和伸长率，单索在两个支撑上有或没有高差，承受均匀分布的荷载(或间隔均匀分布的荷载)和荷载集中在许多点。算例与其他方法的计算结果进行了比较。

期刊介绍： Engineering Solid Mechanics (ESM) is an online international journal for publishing high quality peer reviewed papers in the field of theoretical and applied solid mechanics. The primary focus is to exchange ideas about investigating behavior and properties of engineering materials (such as metals, composites, ceramics, polymers, FGMs, rocks and concretes, asphalt mixtures, bio and nano materials) and their mechanical characterization (including strength and deformation behavior, fatigue and fracture, stress measurements, etc.) through experimental, theoretical and numerical research studies. Researchers and practitioners (from deferent areas such as mechanical and manufacturing, aerospace, railway, bio-mechanics, civil and mining, materials and metallurgy, oil, gas and petroleum industries, pipeline, marine and offshore sectors) are encouraged to submit their original, unpublished contributions.
