螺旋箍筋在高层框架中的抗震作用

本文论述螺旋形箍筋在高层框架结构延性方面的效果。使用螺旋形箍筋,比使用其他形式的箍筋能更好地与纵筋一起约束柱核心混凝土,提高柱的强度和延性,从而,使高层建筑框架结构的抗震能力也随之提高。本文建议在工程设计中广泛使用螺旋形箍筋。

APPLICATION OF SCREW HOOP IN ANTI-SEISMIC FRAMEWORK OF HIGHRISE BUILDING

This paper presents the effect of screw hoop on the ductility of highrise building framework. The screw hoop, which is better than other kinds of hoop, is tied together with stringer to restrict concrete core of column. The strength and ductility of column may be increased, therefore the anti-seismic ca- pability of highrise building can be also increased. The paper suggests that the screw hoop should be extensively used for engineering design.
