Historic constructions are common in Europe, but natural hazards can produce significant damage. Shear reinforcement of historic walls, especially in seismic areas, is often necessary and new retrofitting methods have recently been proposed to restore or increase the lateral capacity of shear walls. In this paper the combined use of cross-laminated timber panels and steel wire ropes is proposed to reinforce rubble stone masonry walls with the aim of increasing their lateral load capacity while improving the energy performance of the building envelope. An experimental programme was carried out in the laboratory to assess the mechanical effectiveness of this retrofitting method. The results from a series of quasi-static cyclic shear tests are presented. The test programmes are described and the analysis of test results is included. The potential benefits and limitations regarding the use of the proposed combined method for reinforcing masonry structures are discussed, with an emphasis on the in-plane behaviour.

用木板和钢丝绳对石墙进行抗震改造

历史建筑在欧洲很常见，但自然灾害会造成重大破坏。历史墙的抗剪加固，特别是在地震区，通常是必要的，最近提出了新的改造方法来恢复或增加剪力墙的侧向承载力。在本文中，提出了交叉层压木板和钢丝绳的组合使用来加固碎石砌体墙，目的是增加它们的横向承载能力，同时提高建筑围护结构的能源性能。在实验室中进行了一项实验计划，以评估这种改造方法的机械有效性。介绍了一系列准静态循环剪切试验的结果。描述了测试程序并包括了测试结果的分析。
