【提要】從普通磚砌體的受壓試驗結(jié)果出發(fā)，借鑒混凝土本構(gòu)模型，全面描述了普通磚砌體受壓的本構(gòu)關(guān)系。同時采用5次多項式的數(shù)學(xué)模型，用一條曲線反映普通磚砌體受壓的應(yīng)力應(yīng)變?nèi)^程，對比結(jié)果表明該模型是可行的，能滿足工程計算和有限元分析的要求。
【關(guān)鍵詞】  磚砌體  受壓  本構(gòu)關(guān)系  應(yīng)力應(yīng)變曲線
Constitutive Relationship of Brick Masonry/Lü Weirong1, 2,  Shi Chuxian1(1 College of Civil Engineering, Hunan University, Changsha 410082, China; 2 Department of Civil Engineering, Hunan University of Technology, Zhuzhou 412008, China)
Abstract:The stressstrain curve of common brick masonry in compression is completely
described based on compress test results of literature and constitutive relationship of concrete. At the same time,a mathematic model of 5 degrees polynomial is used,and the whole process of common brick masonry in compression is described by one smooth curve. The results of contrast indicate that the proposed model is feasible and meets the request of engineering calculation and finite element analysis.
Keywords:common brick masonry; compress; constitutive relationship; stressstrain curve
