Abstract: To improve anti-collapse behavior of an existing masonry structure under earthquake action, a new thin beam-column system was proposed. In order to verify the efficiency of the strengthening method, as one of the series projects, this paper focuses on the cooperative work behavior of an existing masonry corner wall and an externally added reinforced concrete thin column under horizontal cyclic loads. Six 1/2 scaled masonry corner walls were built. Among them, three specimens were strengthened with externally added thin reinforced concrete columns. Then quasi-static tests were conducted to study the seismic behavior of the walls under different axial loads and cyclic horizontal loads from different directions. Afterward, the discrete element method (DEM) was adopted for numerical simulation on the test specimens and the prototype walls. Based on the verified simulation methods, parameter analysis was conducted. Test and simulation results showed that the externally added thin reinforced concrete column could work together well with an existing masonry corner wall by using the construction measures proposed in this paper. The maximum peak load-bearing capacity of a corner wall can be increased 5.32 times by strengthening. The strengthening efficiency for bearing capacity decreased, as the wall thickness was increased. Whereas the concrete strength exhibited negligible effect on the lateral load bearing capacity of the strengthened walls. [ABSTRACT FROM AUTHOR]
