论文摘要
该论文涉及通过纺织增强砂浆（TRM）增强的砌体元素的建模，这是一种近表面系统，该系统由嵌入在砂浆层中的基于纤维的网格或纺织品制成。最近，作者着重于TRM复合材料的机械表征，通过使用免费的开源有限元代码OOFEM开发了一种详细的级别建模方法，以模拟TRM优惠券上的实验测试（拉出测试，拉伸测试，拉伸测试，剪切键测试，剪切键测试，剪切键测试和平面剪切测试）。该模型能够说明单个组件的故障（例如，纤维拉伸失效，砂浆破裂和压碎）以及它们的相互作用（从砂浆中脱离了纤维和砌体底物的砂浆）。在本文中，详细的建模方法应用于受到对角线压缩，面内和平面外弯曲测试的TRM加强砌体元件的模拟，并研究了砌体的典型故障模式。进行非线性静态分析，并从实验证据中推导出材料和界面的非线性。与一些实验结果和参数研究的比较允许证明模型的可靠性及其对主要成分特征的敏感性。
The paper concerns the modelling of masonry elements strengthened through Textile Reinforced Mortar (TRM), a near surface system made of fiber-based grids or textiles embedded in mortar layers. Recently, the author, focusing on the mechanical characterization of TRM composites, developed a detailed level modelling approach by using the free, open-source Finite-Element code OOFEM, for the simulation of experimental tests on TRM coupons (pull-out tests, tensile tests, shear bond tests and in-plane shear tests). The model was capable to account for the failure of single components (e.g. the fibers tensile failure, the mortar cracking and crushing), as well as of their interactions (the debonding of the fibers from the mortar and of the mortar from the masonry substrate). In this paper, the detailed-level modelling approach is applied to the simulation of TRM strengthened masonry elements subjected to diagonal compression, in-plane and out-of-plane bending tests, investigating on the typical failure modes of masonry. Non-linear static analyses are performed, with nonlinearities of materials and interfaces deduced from experimental evidences. The comparison with some experimental results and a parametric study allowed to evidence the reliability of the models and their sensitivity to the main components characteristics.
