［摘要］國(guó)家博物館老館建成于1959年8月，占地面積5.05萬(wàn)m²，建筑面積6.5萬(wàn)m²，為建國(guó)初期首都十大建筑之一。由于受建設(shè)時(shí)期歷史條件的限制，在建筑規(guī)模、材料、質(zhì)量、設(shè)施等方面都不能滿足現(xiàn)在國(guó)家博物館發(fā)展的需要和安全使用要求。由《中國(guó)國(guó)家博物館檢驗(yàn)報(bào)告》可知：老館結(jié)構(gòu)梁、板開(kāi)裂較多，裂縫最大寬度梁為1.5mm、板為2.3mm，并有少數(shù)地方出現(xiàn)露筋現(xiàn)象?？拐痱?yàn)算表明：原結(jié)構(gòu)在8度多遇地震作用下不能滿足國(guó)家現(xiàn)行規(guī)范要求，部分區(qū)段的結(jié)構(gòu)安全可靠度已經(jīng)較低，必須采取必要的加固措施。老館加固改造工程的結(jié)構(gòu)設(shè)計(jì)，運(yùn)用結(jié)構(gòu)綜合抗震能力分析方法和多種最新的加固手段，在保持原有建筑風(fēng)貌的前提下，實(shí)現(xiàn)了提高抗震能力和改善使用功能的協(xié)調(diào)，取得了重大工程加固改造的良好經(jīng)驗(yàn)。

Abstract:The old National Museum of China was built in August 1959, with the site area of 50 500m² and the gross floor area of 65 000m², and it is one of the 10 master buildings in Beijing in 1950’s. Due to restrictions in that period, the volume, material, quality and equipments of the National Museum of China could not meet its development and safety requirements. According to the Inspection Report of the National Museum of China， there are number of cracks in the beams and floor slabs of the building, among them the biggest crack is 1.5mm in the beam and 2.3mm in the floor, even rebars can be seen in the individual places. The structural seismic check indicates that several parts are very risky and could not meet the requirements of the current national codes under the 8 degree earthquake action, which have to be strengthened. In the structural strengthening design, the analysis approach of compound seismic capability and various new strengthened methods were applied to enhance the seismic capability and improve the service function simultaneously on the premise of reserving the original architectural style of museum. The article sums up the experiences in retrofitting and strengthening the important project.

Keywords:the old National Museum of China; structure seismic; appraisal; retrofitting and strengthening  design
