A　seismic　retrofitting　scheme　of　a　concrete　building,　constructed　based　on　Chinese　Standard　TJ11-78,　is　designed　by　using　BRB　concrete　frames.　Comparisons　are　made　on　seismic　behavior　between　the　original　and　the　retrofitted　structure　in　terms　of　seismic　actions,　displacement,　the　ratio　of　axial　force　to　strength,　and　inter-story　shear　forces,　etc.　Nonlinear　static　pushover　analysis　and　dynamic　analysis　are　conducted.　Plastic　hinge　status,　hinge　distribution　features,　and　inner　forces　envelopes　are　compared.　Results　have　shown　that　the　retrofitting　technology　alleviates　seismic　forces　on　existing　frames,　and　avoids　the　significant　axial　compression　force,　shearing　force,　and　inter-story　drift　angle　occurring　at　the　bottom　stories　of　the　original　frame.　By　applying　this　method,　energy　dissipation　and　seismic　reduction　can　be　enhanced,　and　better　seismic　behavior　of　concrete　frames　can　be　achieved.　Static　lowly　cyclic　loading　tests　are　also　conducted,　demonstrating　effective　seismic　damage　reduction　and　plastic　hinge　distribution　transfer.　With　this　method,　indoor　wet　construction　work　can　be　avoided,　which　is　beneficial　for　both　constructors　and　residents.
