钢筋混凝土结构是我国多层及高层建筑常用的结构形式之一。近年地震震害和设计经验以及试验研究使这类结构的抗震设计,从概念设计、计算方法到构造措施都有很大的发展。《工业与民用建筑抗震设计规范》(TJ-78)修订本的送审稿中吸取了很多新的内容。本文介绍多层和高层钢筋混凝土房屋抗震设计有关内容,包括:抗震设防要求、抗震等级划分、设计基本原则、计算要点和主要构造措施。
Reinforced concrete structure is one of the commonly used structural forms of multi-storey and high-rise buildings in China. In recent years, seismic damage, design experience, and experimental research have made the seismic design of such structures a great development from conceptual design, calculation methods, and structural measures. The revised manuscript of the “Code for the Seismic Design of Industrial and Civil Buildings” (TJ-78) drafted a lot of new content. This paper describes the contents of seismic design for multi-storey and high-rise reinforced concrete buildings, including: seismic fortification requirements, division of seismic levels, basic design principles, calculation points, and major structural measures.
