Abstract: The commercial buildings are RC frame structures. Due to the use of functional changing to the original structure, modification and reinforcement measures must be taken. The structural checking computation of bearing capacity before strengthening, reinforcing positions and later seismic reinforcement method according to different component in actual construction were introduced.  Suggestions that engineer should pay attention to in the construction were given. The measures about the foundation treatments, columns, beams and plates of the comprehensive seismic reinforcement measures have a certain practical typical.
Keywords: renovation and strengthening; frame structure; seismic reinforcement method; reinforcement measure
