七十年代以来,一些经济发达国家受石油危机等影响,出现经济萧条、能源不足等问题,建设规模相对缩小,但建筑科学技术水平仍不断有所提高。建筑科学技术发展的特点是,从五、六十年代以解决建造数量和建设速度为重点转向提高建筑质量,改善居住环境,节约能源和资源等方面。十几年来取得了不少新的成就。 Since the 1970s, some economically developed countries have been affected by the oil crisis and other problems. There have been economic slumps, energy shortages and other issues. The scale of construction has been relatively reduced, but the level of construction science and technology has continued to increase. The development of building science and technology is characterized by focusing on improving the construction quality, improving the living environment, and saving energy and resources, focusing on the number of construction and speed of construction in the 1950s and 1960s. More than 10 years have achieved a lot of new achievements.
