Abrasion Resistance of Cement Mortar with Different Pozzolanic Compositions and Matrices
Yetgin, Sukru; Cavdar, Ahmet (Asce-Amer Soc Civil Engineers, 2011)Abrasion of concrete occurs due to scraping, rubbing, skidding, or sliding of objects on its surface. The abrasion resistance of concrete is influenced by a number of factors, such as compressive strength, surfacing finish, ... -
Earthquake Performance of Reinforced-Concrete Shear-Wall Structure Using Nonlinear Methods
Cavdar, Ozlem; Cavdar, Ahmet; Bayraktar, Ender (Asce-Amer Soc Civil Engineers, 2018)In earthquake engineering, the performance-based design method is used to determine the expected performance level of structures under an earthquake effect. The level of performance is related to the damage situation that ... -
The effects of high temperature on mechanical properties of cementitious composites reinforced with polymeric fibers
Cavdar, Ahmet (Elsevier Sci Ltd, 2013)Polymeric fibers are cheap and popular materials used in the concrete industry, and they may improve the mechanical properties of cementitious composites under high temperature. In this study, three different types of ... -
Effects of random material and geometrical properties on structural safety of steel-concrete composite systems
Cavdar, Ozlem; Bayraktar, Alemdar; Cavdar, Ahmet (Wiley, 2011)A stochastic finite element-based algorithm for probabilistic analysis of structural systems made of composite sections with random material and geometrical properties under earthquake forces is proposed in this paper. ... -
The Effects of Types and Content of Fibers on Mechanical Properties of Cementitious Composites
Cavdar, Ahmet (Istanbul Technical Univ Faculty Civil Engineering Printhouse, 2012)In this study, four different types of fibers are added to cement mortars and it is aimed to investigate their mechanical contributions to mortars, comparatively. Polypropylene (PP), carbon (CF), glass (GF) and polyvinyl ... -
Investigation of abrasion resistance of cement mortar with different pozzolanic compositions and subjected to sulfated medium
Cavdar, Ahmet; Yetgin, Suekrue (Elsevier Sci Ltd, 2010)The durability phenomenon for concrete, or cement mortar, has gained attention recently as one of the important mechanical properties. It can be described as concrete's resistance to the destructive influences of a medium ... -
Investigation of freeze-thaw effects on mechanical properties of fiber reinforced cement mortars
Cavdar, Ahmet (Elsevier Sci Ltd, 2014)Fibers are used for improving some properties of conventional concrete (which is a brittle material) such as tensile strength, abrasion resistance, absorption and crack control. This study investigates the usability of ... -
Investigation of mechanical and mineralogical properties of mortars subjected to sulfate
Cavdar, Ahmet; Yetgin, Suekrue (Elsevier Sci Ltd, 2010)The durability can be described as concrete's resistance to the destructive influences of a medium containing acid, sulfate and/or various chemicals and mechanical effects. The main objective of this study is investigation ... -
A New Nomogram Proposal to Determine Concrete Compressive Strength by Combined Nondestructive Testing Methods
Bingol, Sinasi; Cavdar, Ahmet (Taylor & Francis Inc, 2018)Concrete is the most widely used construction material in contemporary construction technology. In particular, it holds an important place in the building industry in the world. Since concrete is a nonhomogeneous material, ... -
Stochastic finite element analysis of structural systems with partially restrained connections subjected to seismic loads
Cavdar, Oezlem; Bayraktar, Alemdar; Cavdar, Ahmet; Kartal, Murat Emre (Techno-Press, 2009)The present paper investigates the stochastic seismic responses of steel Structure systems with Partially Restrained (PR) connections-by using Perturbation based Stochastic Finite Element (PSFEM) method. A stiffness matrix ... -
A study on the effects of high temperature on mechanical properties of fiber reinforced cementitious composites
Cavdar, Ahmet (Elsevier Sci Ltd, 2012)The flexural strength and ductility properties of cementitious composites (mortar) under high temperature may be significantly improved by incorporating different types of fibers. In this study, four different types of ...
