Abstract

During recent seismic events (2016 in central Italy, 2014 in China’s Ludian County, etc.), masonry structures have shown their vulnerability to in plane actions. A lot of retrofitting solutions are today available to increase the in-plane resistance of existing masonry walls. The seismic strengthening technique presented in this chapter is a retrofitting system for masonry buildings developed over 10 years at the Karlsruhe Institute of Technology (KIT) in Germany, Institute of Reinforced Concrete and Building Materials (Germany). It consists of a multiaxial hybrid fibre grid embedded in an inorganic natural hydraulic lime (NHL) mortar. Due to its composition, it is perfect compatible with the masonry substrate and applicable for indoor as well as outdoor applications. Moreover, it improves the local and the overall structural capacity of a masonry building with minimum mass increase. The intensive experimental campaign carried out on this strengthening system at the Karlsruhe Institute of Technology (KIT) and its results are presented and discussed in this chapter.

eq -网格:砌体建筑多轴向抗震加固系统

在最近的地震事件中(2016年在意大利中部，2014年在中国鲁甸县等)，砌体结构已经显示出对平面作用的脆弱性。现在有很多改造方案可以增加现有砖石墙的面内阻力。本章介绍的抗震加固技术是德国卡尔斯鲁厄理工学院(KIT)钢筋混凝土和建筑材料研究所(德国)10多年来开发的砖石建筑加固系统。它由嵌入无机天然水力石灰(NHL)砂浆中的多轴混合纤维网格组成。由于其组成，它与砌体基材完美兼容，适用于室内和室外应用。在最小质量增加的情况下，提高了砌体建筑的局部和整体结构能力。在卡尔斯鲁厄理工学院(KIT)对这种强化系统进行的密集实验活动及其结果在本章中进行了介绍和讨论。
