介绍了抛物线拱结构的特点,以某对称的单跨两铰拱为例,采用精确计算法与简化计算法,计算分析了该拱结构的内力,并探讨了两种计算方法的优劣势和适用范围,为抛物线拱结构内力计算方法的选择提供参考。
The characteristics of the parabolic arch structure are introduced. Taking a symmetrical single-span two-hinged arch as an example, the internal force of the arch structure is calculated by the precise calculation method and the simplified calculation method, and the advantages and disadvantages of the two calculation methods are discussed It provides reference for the calculation of the internal force of parabolic arch structure.
