Abstract

The present paper treats the free vibration problem of the masonry wall strengthened with thin composite plate by viscoelastic adhesive layer. For this goal two steps are considered in the analytical solution. In the first one, an efficient homogenisation procedure is given to provide the anisotropic properties of the masonry wall. The second one is dedicated to purpose simplified mathematical models related to both in-plane and out-of-plane vibration problems. In these models, the higher order shear theories (HSDT's) are employed for a more rigours description of the shear deformation trough the masonry wall and the composite sheet. Ritz's method is deployed as solution strategy in order to get the natural frequencies and their corresponding loss factors. The obtained results are validated with the finite element method (FEM) and then, a parametric study is undertaken for different kinds of masonry walls strengthened with composite sheets.
粘弹性粘接层纤维复合贴片加固砌体墙体的振动和阻尼特性
本文研究了粘弹性粘接层薄复合板加固砌体墙体的自由振动问题。为了实现这一目标,在解析解中考虑了两个步骤。在第一种方法中,给出了一种有效的均质化程序来提供砌体墙体的各向异性特性。第二部分是关于面内和面外振动问题的简化数学模型。在这些模型中,采用高阶剪切理论(HSDT’s)对砌体墙体和复合材料板的剪切变形进行了更严格的描述。采用里兹法作为求解策略,得到固有频率及其相应的损耗因子。用有限元法对所得结果进行了验证,并对不同类型的复合板加固砌体墙体进行了参数化研究。
