唐山地震中,钢筋混凝土房屋遭受不同程度破坏,包括一些框架结构全部倒塌,从而对如何提高钢筋混凝土结构抗震性能及合理的进行抗震设计提出了新的课题。近十年来,全国有不少单位结合框架、框剪及剪力墙三种结构体系进行大量的构件、节点及结构的抗震性能试验研究,提出了有关抗震设计方法及构造措施。本文所介绍的设计要点,反映了上述研究成果中的主要内容,同时也吸取了一些国外的设计经验。
In the Tangshan earthquake, the reinforced concrete houses suffered from various degrees of damage, including some collapsed frame structures. This raised new issues for how to improve the seismic performance of reinforced concrete structures and reasonably perform seismic design. In the past decade, many units across the country have conducted a large number of structural, joint, and structural seismic performance test researches on three structural systems including frame, frame shears, and shear walls, and proposed related seismic design methods and structural measures. The design points introduced in this paper reflect the main contents of the above research results, and also draw on some foreign design experience.
