The reinforcement design of Lshaped roof room, which consists of the stairwell and elevator well, was optimized and analyzed. Results prove that PKPMbased reinforcement design optimization is effective and practicable. Design laws were summarized that the reinforcement done for the irregular plane room should consider the whole reinforcement, in order to avoid excessive impact on the seismic performance of other parts by the partial reinforcement. Simply increasing the thickness of the surface layer to increase the effect of mortar surface layer reinforcement method is not recommended. Selecting the upper limit of bar spacing according to the code is recommended when use doublesided steel mesh mortar surface reinforcement method.Keywords:brick-concrete structure; medical building; seismic evaluation; reinforcement; project optimization*中央高?；究蒲袠I(yè)務(wù)費專項資金(12CX06078A)，勝利油田技術(shù)檢測中心技術(shù)服務(wù)項目(652011JS00019)。作者簡介：周金順，碩士研究生，Email：zhoujinshun@163.com。
