Active and non-active porosity in concrete. Part I: Experimental evidence

The findings of an experimental study are described, documenting and quantifying the influence of concrete porosity on its mechanical properties in saturated and dry states. Concrete porosity consists of capillary and entrained air, and described respectively as active and non-active, depending on its influence on mechanical properties with changing moisture state. It was found that the active (capillary) porosity influence on mechanical properties is more pronounced with decreasing moisture. The influence of non-active (entrained-air) porosity on concrete mechanical properties is invariant of moisture state.

Hybrid fiber reinforced self-compacting concrete with a high-volume coarse fly ash
Sahmaran, Mustafa; Yaman, İsmail Özgür (Elsevier BV, 2007-01-01)
This paper presents a study on the fresh and mechanical properties of a fiber reinforced self-compacting concrete incorporating high-volume fly ash that does not meet the fineness requirements of ASTM C 618. A polycarboxylic-based superplasticizer was used in combination with a viscosity modifying admixture. In mixtures containing fly ash, 50% of cement by weight was replaced with fly ash. Two different types of steel fibers were used in combination, keeping the total fiber content constant at 60 kg/m(3). S...
Lifetime performance analysis of existing prestressed concrete bridge superstructures
Akgül, Ferhat (American Society of Civil Engineers (ASCE), 2004-12-01)
A general methodology for lifetime performance analysis of existing prestressed concrete girder bridges is presented. Only the superstructure components (slab and girders) are considered. The framework for the methodology is established by identifying four distinct categories: limit state equations, random variables, deterministic parameters, and constant coefficients. The limit state equations are derived by strictly adhering to the load and capacity formulas and requirements set forth in AASHTO specificat...
Efficiency of Seismic Isolation for Seismic Retrofitting of Heavy Substructured Bridges
Dicleli, Murat; Constantinou, Michael C. (American Society of Civil Engineers (ASCE), 2005-07-01)
In this paper, the efficiency of seismic isolation for seismic retrofitting of bridges with light superstructures and heavy substructures in the state of Illinois is studied. For this purpose, a representative bridge was selected by Illinois Department of Transportation. A detailed structural model of the bridge capable of simulating the nonlinear behavior of its components and soil-bridge interaction effects was first constructed. Iterative multimode response spectrum analysis (IMMRSA) of the bridge were c...
Lateral stiffness of steel plate shear wall systems
Topkaya, Cem (Elsevier BV, 2009-08-01)
The accuracy of the finite element method and strip method of analysis for calculating the lateral stiffness of steel plate shear wall (SPSW) systems is assessed by making comparisons with experimental findings. Comparisons revealed that while both methods provide acceptable accuracy, they also require the generation of sophisticated computer models. In this paper, two alternative methods are developed. The first one is an approximate hand method based on the deep beam theory. The classical deep beam theory...
Overlapping Lattice Modeling for concrete fracture simulations using sequentially linear analysis
Aydın, Beyazıt Bestami; Tuncay, Kağan; Binici, Barış (Wiley, 2018-04-01)
Modeling concrete fracture is important in order to uncover accurately the sources of distress which lead to the damage or failure of structures. Many different numerical approaches have been used in the past employing either a smeared or a discrete cracking approach. Those models have difficulty in capturing the local nature of cracking, as well as the direction of crack propagation. Lattice modeling and peridynamics (PD) are some of the more recent nonlocal fracture simulation tools which possess advantag...
