前言国内外的震害和试验研究表明:框架节点是结构抗震中的薄弱环节之一。并引起国内外学者们的重视。通过近二十年来的试验研究,已有美、新西兰、欧洲一些国家在规范中列入了节点设计条款。我国新修订的《钢筋砼结构设计规范》(TJ10-85)(以下简称新规范)和《工业与民用建筑抗震设计规范》(TJ11—85) Foreword Earthquake damage and experimental research at home and abroad show that: The frame node is one of the weak links in the structural earthquake. And attracted the attention of scholars at home and abroad. Through experimental research in the past two decades, some countries in the United States, New Zealand, and Europe have included node design terms in their specifications. China’s newly revised “Code for Design of Reinforced Concrete Structures” (TJ10-85) (hereinafter referred to as the “new specification”) and “Code for Seismic Design of Industrial and Civil Buildings” (TJ11-85)
