一提起美国的建筑,人们马上会联想到耸入云霄的摩天大厦,标新立异的建筑风格。却没有想到美国房屋建筑行业同样提出旧房的“重复使用周期”和“保留原有建筑”的重要性。在美国也遇到旧房维修、翻建改造工程中结构强度如何计算的问题,尤其对砖木结 When we talk about American architecture, people immediately think of the sky-high skyscrapers and their unconventional architectural styles. However, they did not think that the US housing construction industry also proposed the importance of the “reuse cycle” and “preservation of the original building” of old houses.
