轴心受压砌体本构关系的试验研究

Experiments Study of Masonry Construction Constitutive Relationship under Axial Compression

本文通过利用9个标准砌体试件的轴向受压试验和其他一些学者的试验数据,结合已有的砌体和混凝土的本构模型,提出了一个砌体全曲线本构关系。该本构关系由两段曲线光滑连接而成。其表达式简单,同时又能高度逼近试验曲线,便于工程应用与有限元分析。

Based on 9 standard masonry species experiments data, other research results, and other constitutive relationship of masonry, a constitutive relationship model is put forward. The constitutive relationship described by two smooth curves. It's formula simple and fit experiments data well, so it suite for using FEM analysis.
