国家博物馆老馆结构加固改造中绿色理念的实施

国家博物馆老馆建成于1959年8月,使用至今已50多年。受当时技术和经济条件限制,原有建筑功能已经不能适应当前对国家博物馆的功能要求;结构构件存在不同程度损伤,原结构抗震能力不足,不符合国家现行规范的规定。为尽量减少建筑加固工程量、贯彻绿色设计理念,充分考虑未来技术发展,最大限度地节约资源,此次加固改造工程的结构设计中,通过运用结构综合抗震能力分析方法和新技术,在保持原有建筑历史风貌的前提下,实现了提高建筑抗震能力和改善建筑使用功能的协调,取得了一些既有公共建筑加固改造中绿色理念实施的有益经验。

THE IMPLEMENTATION OF GREEN CONCEPT IN RETROFITTING AND STRENGTHENING DESIGN OF THE OLD NATIONAL MUSEUM OF CHINA

The Old National Museum of China was built in August 1959. Due to restrictions in that period,the museum could not meet its usage requirements. It has been found that damages occurred in some structural members and the structures is insufficient for aseismatic ability,which can not meet requirements of relevant standards. In order to reduce engineering and implement the concept of green design,the reasonable reinforcing project is given with fully considering development of the future technology. While maintaining the original construction under the premise of historical style and features,the aseismatic capability of buildings has been enhanced and the building function has been improved by using comprehensive analysis methods and new technologies. Some useful experiences have been got in the implementation of green concept in public buildings of structural retrofitting and strengthening.
