摘要
回顾了60年来建筑结构抗震在我国的研究进展和设计规范的变革,介绍了抗震设防的基本目标和发展趋势,约束砌体结构和组合砌体结构、钢筋混凝土结构、钢结构和钢-混凝土组合结构、隔震减震抗震技术和非结构构件抗震措施的研究与应用情况。根据60多年来的研究和最近的震害经验指出,在满足现行抗震规范基本要求的条件下,只要采取适当的抗震构造措施,许多常用的结构形式都能经受罕遇地震时强烈的地面震动,避免严重的破坏。为了使结构具有更好的抗震性能,还可以结合性能设计方法采用隔震减震技术。
Reviews the research progresses of earthquake resistance of building structures and the reforms of seismic design codes in 60 years since P. R. China is founded. The basic target and development tendency of earthquake protection are introduced. The features of research and application of earthquake resistance in confined masonry structure and its combination with reinforced concrete members, steel structures, steel-concrete composite structures, seismic isolation technology and non-structural components are discussed as well. Based on research results and experience from recent destructive earthquakes, it is pointed out that if the basic requirements of current seismic design code are complied and the adequate structural details are adopted, all the listed normal structures enable to resist the strong ground shock during the maximum considered earthquake and avoid serious damage. In order to improve earthquake resistance, it is suggested to use seismic isolation and energy dissipation technology in performance based seismic design.
