混凝土单跨结构抗震加固方案研究

The Researth on Single-span Reinforced Concrete Progrom of Seismic

目前已建的中小学教学楼中有许多属于单跨或单跨加悬挑外廊的结构形式。这种结构形式安全储备低,在地震作用下,倒塌的可能性很大。现行规范已经提出抗震设计的框架结构不宜采用单跨框架。结合安徽和县地区中小学教学楼抗震加固工程实例,介绍了实际工程中可行的几种单跨结构加固方案。

Now so many constructed primary and middle school teaching buildings used the structure form of Single-span.The form is low safety,it＇s probably collapses during the earthquake.The current seismic design specifications have been proposed framework should not be a single span frame.In this paper,the practical engineering feasibility of several single-span structure reinforcement are introduced based on engineering example of primary and middle school teaching build in He County of Aanhui province.
