论文摘要
本文旨在分析评估破裂细长的砌体元素的固有频率。在线性扰动的框架中解决了问题，在实现了永久载荷的平衡后，在负载条件下研究了结构的小振荡。考虑了由砌体样材料制成的砌体束元素，并得出了梁的基本频率的某些明确表达式作为外部载荷的函数，并得出了施加的变形的幅度。通过有限元分析验证了分析结果。
The present paper aims at analytically evaluating the natural frequencies of cracked slender masonry elements. The problem is dealt with in the framework of linear perturbation, and the small oscillations of the structure are studied under loaded conditions, after the equilibrium for permanent loads has been achieved. A masonry beam element made of masonry-like material is considered, and some explicit expressions of the beam's fundamental frequency as a function of the external loads and the amplitude of imposed deformations are derived. The analytical results are validated via finite-element analysis.
