［摘要］湖南益陽奧林匹克公園體育場結(jié)構(gòu)因年久失修和2008年加固改造不合理，導致結(jié)構(gòu)安全性已不滿足現(xiàn)行規(guī)范要求，經(jīng)檢測判定不能繼續(xù)使用。根據(jù)現(xiàn)行規(guī)范，綜合考慮加固效果、施工方便以及節(jié)省造價等因素，提出了調(diào)整傳力路徑、增加水平支撐體系、包鋼加強截面、修補焊縫等多種加固方法。經(jīng)過對加固前后結(jié)構(gòu)體系的計算分析對比，加固方案有效改善了結(jié)構(gòu)傳力體系，提高了結(jié)構(gòu)承載能力，改善了結(jié)構(gòu)的應力水平和變形。

Abstract:Due to lack of maintenance and unreasonable reinforcement and reformation in 2008, the structural security of Yiyang Olympic Park Stadium in Hunan can not meet the normal service requirements of current design specifications. The stadium is no longer suitable for continuing operation according to the inspection report. Considering reinforcement effects, convenience construction and saving cost, several reinforcement methods were proposed according to the current design specifications, such as adjusting load transfer path, adding lateral supporting system, reinforcing tube section with steel slats, repairing welds, and so on. Through the comparison and analysis of calculation results of the structural system before and after reinforcement, it shows that the structural force transfer path, the bearing capacity of the structure and the stress level and deformation of the structure can be effectively improved by the reinforcement scheme.
Keywords:stadium; reinforcement design; spatial structure; lateral support
