| 1 | Shrinkage behavior of self-compacting concrete显示文摘In the structures where long-term behavior should be monitored and controlled, creep and shrinkage effects have to be included precisely in the analysis and design procedures. Shrinkage varies with the constituent and mixture proportions, and depends on the curing conditions and the work environment as well. Self-compacting concrete (SCC) contains combinations of various components, such as aggregate, cement, superplasticizer, water-reducing agent and other ingredients which affect the properties of the SCC including shrinkage. Hence, the realistic prediction shrinkage strains of SCC are an important requirement of the design process for this type of concrete structures. This study reviews the accuracy of the conventional concrete (CC) shrinkage prediction models proposed by the international codes of practice, including CEB-FIP (1990), ACI 209R (1997), Eurocode 2 (2001), JSCE (2002), AASHTO (2004; 2007) and AS 3600 (2009). Also, SCC shrinkage prediction models proposed by Poppe and De Schutter (2005), Larson (2007), Cordoba (2007) and Khayat and Long (2010) are reviewed. Further, a new shrinkage prediction model based on the comprehensive analysis on both of the available models, i.e., the CC and the SCC is proposed. The predicted shrinkage strains are compared with the actual measured shrinkage strains in 165 mixtures of SCC and 21 mixtures of CC. | Farhad ASLANI Shami NEJADI | 2012 | Journal of Zhejiang University-Science A(Applied Physics & Engineering)2012,13,6: | 3 |

| 5 | Empirical models and design codes in prediction of modulus of elasticity of concrete显示文摘Modulus of Elasticity (MOE)is a key parameter in reinforced concrete design.It represents the stressstrain relationship in the elastic range and is used in the prediction of concrete structures.Out of range estimation of MOE in the existing codes of practice strongly affect the design and performance of the concrete structures.This study includes: (a)evaluation and comparison of the existing analytical models to estimating the MOE in normal strength concrete,and (b)proposing and verifying a new model.In addition,a wide range of experimental databases and empirical models to estimate the MOE from compressive strength and density of concrete are evaluated to verification of the proposed model. The results show underestimation of MOE of conventional concrete in majority of the existing models.Also,considering the consistency between density and mechanical properties of concrete,the predicted MOE in the models including density effect,are more compatible with the experimental results. | Behnam VAKHSHOURI Shami NEJADI | 2019 | Frontiers of Structural and Civil Engineering2019,13,1: | 1 |
