为了克服现有钢筋混凝土（RC）建筑在设计和施工阶段所犯的错误，对结构进行加固是必要的。近年来，对经济、简便的混凝土砌体填充墙加固方法的研究日益深入。用钢筋网和附加砂浆层、纤维增强聚合物和预制混凝土板加固砌体填充墙已成为这些技术的前沿。本文对砌体墙内填充钢筋混凝土框架进行了钢筋网加砂浆层加固试验研究。选择这种方法的一个最重要的原因是，加强可以实现较少的成本，工艺和不需要准备模具进行加强。目前研究的主要变量是：框架和填充墙的锚固长度、间距和配置，附加层在墙内或墙外。在重复地震荷载的作用下，共建造了11个试件，1/3比例尺，一间房，一层无延性混凝土框架，砌体填充墙，代表了现有建筑中使用低压缩混凝土的缺陷，箍筋不足，梁与柱相比较强。载荷-位移行为，初始刚度，位移延性率和能量消耗能力被解释。
Strengthening of structures may become a necessity to overcome the mistakes made during the design and construction phases of existing reinforced concrete (RC) buildings. In recent years, researches have been intensified on the economical and easy application of the strengthening of masonry infill walls in RC buildings. Strengthening of masonry infill wall with steel reinforcing mesh and additional mortar layer, fiber reinforced polymers and prefabricated concrete panels have become in the forefront of these techniques. In this study, the RC frame infilled with masonry walls and strengthened with steel reinforcing mesh and mortar layer was examined experimentally. One of the most important reasons for choosing this method is that the strengthening could be achieved with less cost, workmanship and without the need to prepare molds for reinforcement. The main variables that have been examined in the current study are: the anchorage length, spacing, and configuration which were applied to the frame and infill wall and the added layer are on the inside or outside wall. A total of 11 specimen, 1/3 scale, one‐bay, one‐story nonductile RC frames with masonry infill wall which representing the deficiency in the existence building by using low‐compressive concrete, insufficient stirrups, and strong beam in comparison to column were constructed and tested under the effect of repeated seismic load. Load–displacement behaviors, initial stiffness, displacement ductility rates, and energy consumption capacities are interpreted.
