| Abstract |
The importance of seismic reinforcement of buildings was emphasized as the number of earthquakes in Korea increased. Therefore, it is
necessary to secure the safety of masonry structures with a large number of elapsed years and a low seismic design and reinforcement ratio,
and for this purpose, safety evaluation and seismic reinforcement through analysis should be made. To this end, a force-deformation
relationship according to the destruction mode of the masonry wall was presented, and a nonlinear static analysis of non-reinforced and
reinforced masonry was performed to reflect the performance improvement when reinforced with high-strength flame-retardant reinforced fiber
sheet and securing safety for other destruction modes. As a result of the experiment, the diagonal tension shear performance improved by
1.202 times when reinforcing one side after removing plastering, and the adhesive stress was 0.311 MPa. As a result of the analysis
reflecting this, in the case of non-reinforced masonry, the prevention of collapse for the return period of 2,400 years was not satisfied, but in
the case of reinforced masonry, the target performance was achieved. |
