摘要
加强结构抗扭性能以减少地震时扭转造成的危害是结构设计的重要概念,《建筑抗震设计规范》(GB50011—2001)和《高层建筑混凝土结构技术规程》(JGJ3—2002)中对结构扭转规则性作了定量的规定,针对结构工程师在执行过程中出现的一些困难和疑惑,从概念上剖析了规范和规程的有关规定的意义和产生疑惑的原因,并提出了处理方法和建议。
To enhance the torsion resistance ability of a structure and then to reduce the disaster under earthquake is a significant concept in structure design. There are some relevant articles in Code for eismic Design of Buildings （GBS0011-2001） and Technical Specification for Concrete Structure of Tall Buildings （JGJ3-2002）. However, some difficulties and uncertainties are there when engineers conduct those articles in their design works. Discussion and proposals are given.
