  • Saatcioglu & Razvi 混凝土本构介绍(Introduction

箍筋的配置对核心混凝土具有侧向约束作用,可以显著提高混凝土的强度和延性。合理考虑这一约束作用是保证结构非线性地震反应分析结果准确性的基础。工程实践中,常采用约束混凝土本构模型来考虑箍筋对核心混凝土的约束作用。目前已提出多种模型,其中Saatcioglu & Razvi 混凝土本构模型是较为常用的约束混凝土模型之一,该模型由Murat Saatcioglu和Salim R. Razvi[1]于1992年提出。Saatcioglu & Razvi 混凝土本构模型和Mander[2]混凝土本构模型的思路基本一致,都是通过将箍筋约束的作用等效为侧向约束应力,进而确定约束混凝土本构的峰值强度和峰值强度对应的应变。两者不同的是,Mander模型直接利用两个方向的等效侧向约束力,因此当两个方向侧向约束力不相同的时候,峰值强度的计算就比较麻烦,不能直接用公式获得,而Saatcioglu & Razvi混凝土本构模型则采用等效均匀侧向约束力,即对于两个方向侧向约束不相等地情况,将侧向约束力等效为各向均匀分布侧向约束力的情况来计算,因此,相对于Mander模型,Saatcioglu & Razvi混凝土本构模型的约束混凝土峰值强度的计算较方便。Saatcioglu & Razvi混凝土本构模型可以考虑圆形截面、矩形截面、长方形截面,可考虑多种配箍形式,并可通过等效侧向力叠加的方式考虑截面中存在多种配箍形式的情况。
