一、前言 埋铁件是装配式钢筋混凝土结构重要的连结方式之一,铁件虽小,关系极大,所以予埋件的设计正确与否直接影响工程质量和安装速度。另外,从大量震害调查资料中发现,不少厂房倒塌是由于节点破坏而引起的,可见节点的连接设计及构造形式的不合 I. INTRODUCTION Buried iron pieces are one of the important connecting methods for fabricated reinforced concrete structures. Iron pieces are small and have a great relationship. Therefore, whether or not the design of embedded pieces is correct affects the project quality and installation speed. In addition, from a large number of seismic survey data, it is found that many plant collapses are caused by the destruction of the joints. It can be seen that the connection design and structural forms of the nodes are different.
