黃磊1，王小平2，張達生1（1 武漢市建筑設計院，武漢 430014；2 武漢理工大學，武漢 430070）［摘要］依據(jù)輕骨料混凝土單軸全應力-應變關系曲線，獲得輕骨料混凝土損傷塑性模型的單軸應力-非彈性應變關系、單軸應力-開裂應變關系、損傷值-非彈性應變關系與損傷值-開裂應變關系，利用數(shù)值方法模擬輕骨料混凝土單軸壓縮試驗，結果表明，采用損傷塑性模型獲得的有限元計算模擬值與試驗擬合值吻合較好。［關鍵詞］輕骨料混凝土；損傷塑性本構模型；ABAQUS；單軸壓縮試驗中圖分類號：TU375-01文獻標識碼：A文章編號：1002-848X(2012)07-0081-03Application research on-damaged plasticity model of lightweight aggregate concrete under uniaxial stressHuang Lei1, Wang Xiaoping2, Zhang Dasheng1(1 Wuhan Architectural Design Institute, Wuhan 430014, China; 2 Wuhan University of Technology, Wuhan 430070, China)Abstract: According to uniaxial stress-strain curves of the lightweight aggregate concrete, uniaxial stress-inelastic strain curves, uniaxial stress-cracking strain curves, damage-inelastic strain curves and damage-cracking strain curves were obtained. Uniaxial compression experiment was simulated by numerical method, the results show that the values calculated by finite element method using damaged plasticity model can meet the ones obtained by experiment well.Keywords: lightweight aggregate concrete; damaged plasticity model; ABAQUS; uniaxial compression experiment作者簡介：黃磊，碩士，助理工程師， Email：hl_civil@163.com。參考文獻［1］葉列平，孫海林，陸新征，等.高強輕骨料混凝土結構性能、分析與計算［M］.北京:科學出版社,2009.［2］劉哲鋒,蘇志力,楊偉軍，等. 輕骨料混凝土與普通混凝土框架結構的抗震性能分析［J］.建筑結構，2010，40(2)：22-24.［3］ABAQUS Inc.
