ABSTRACT

In this study, out-of-plane experimental tests are performed on masonry partitions in reinforced concrete frames. The out-of-plane strength of reference as-built specimens with and without arching action is assessed. Then, specimens strengthened with an FRCM or with an FRP are tested in absence of arching effect. The application of composite materials significantly increases the out-of-plane strength. However, a brittle out-of-plane failure of the infill is avoided only if FRCM is applied. The seismic safety of case-study strengthened partitions without arching effect is compared with that of analogous strengthened partitions in which arching action can occur.

摘要

在这项研究中，对钢筋混凝土框架中的砌体隔板进行了平面外实验测试。评估具有和不具有拱形作用的参考竣工试样的平面外强度。然后，在没有拱形效应的情况下测试用 FRCM 或 FRP 加固的试样。复合材料的应用显着提高了面外强度。然而，只有应用 FRCM 才能避免填充物的脆性平面外破坏。比较了没有拱效应的加筋隔墙与可能发生拱作用的类似加筋隔墙的抗震安全性。
