一、发展概况预应力钢结构是本世纪中叶钢结构领域内发展起来的一门分支学科,对它的研究和应用已有40年历史。由于它能改善钢结构受力特性,扩大高强钢材使用范周,节约钢材,因此受到世界科技先进国家的重视。到目前为止,已经召开了三届国际预应力金属结构学术会议,有苏、美、德、日、瑞典、波兰、捷克等国的专家学者参加,出版过几
I. Development Overview Prestressed steel structures are a branch discipline developed in the field of steel structures in the mid-century of this century. Its research and application have been 40 years old. Because it can improve the stress characteristics of steel structures, expand the use of high-strength steel products Fan Zhou, save steel, so by the world’s advanced science and technology attention. So far, three international academic conferences on prestressed metal structures have been held. Experts and scholars from countries including the Soviet Union, the United States, Germany, Japan, Sweden, Poland, and the Czech Republic have participated in the conference.
