In recent years, both after the devastating earthquake and in the expected earthquake, the buildings reinforced to improve seismic performance have been significantly added. Many structural engineers have spent most of their careers designing new buildings, and they may find themselves not fully prepared for the challenge of seismically reinforcing existing buildings to improve earthquake resistance. This article/poster is intended to briefly summarize the basic strengths and weaknesses of various reinforcement methods, design guidance and reference. Engineers with extensive experience in seismic reinforcement will find this paper quite rudimentary, but the authors believe that many mission planners need this basic guidance.<br>The choice of seismic reinforcement scheme depends on many factors. The programme must correct the deficiencies found in existing building seismic systems and new reinforced components<br>The existing structural system must be structurally incompatible. It must be functionally and sometimes aesthetically compatible and complementary to existing buildings. In historical buildings, the setting of additional elements must take into account the preservation of historical structure and historical atmosphere. The program must meet the owner's performance goals, whether it's life safety, critical facilities, or some form of limited alert to get full operation back up and running quickly after an earthquake. If the building is still occupied during reinforcement work, minimizing interference with the occupants can be a primary issue when choosing the appropriate reinforcement solution. In inhabited buildings, it is usually most satisfying to reinforce the perimeter of the building, and most of the work is done from the outside.
