Biomineralized cement-based materials: impact of inoculating vegetative bacterial cells on hydration and strength
(Elsevier, 2015-01)Biomineralization in cement-based materials has become a point of interest in recent years due to the possibility that such an approach could be used to develop a self-healing cement-based system. The objective of this ... -
Blind identification of site effects and bedrock motion from surface response signals
(Elsevier, 2018-04)A method for blind identification of site effects from two nearby ground surface response signals is presented. The proposed approach makes use of ground surface accelerations from two nearby stations to back-calculate the ... -
Calcium sulfoaluminate cement and supplementary cementitious materials-containing binders in self-healing systems
(Elsevier, 2023-08)Creation of more durable concrete is one pathway to achieving improved sustainability and carbon footprint over a concrete structure's life. Microbially induced calcite precipitation has been shown to densify concrete ... -
Case study for comparative analysis of BIM-based LEED building and nonLEED building

Characterization of site amplification by a parametric study
(Taylor & Francis, 2023)The reliability of Vs30 and the performance of alternative time averaged shear wave velocities (Vsz) and shear wave travel times (Ttz) at various depths, z, were investigated for the estimation of site amplification and ... -
Community resilience-focused technical investigation of the 2016 Lumberton, North Carolina, flood: An interdisciplinary approach
(American Society of Civil Engineers, 2020-08-01)In early October 2016, Hurricane Matthew crossed North Carolina as a Category 1 storm, with some areas receiving 0.38-0.46 m (15-18 in.) of rainfall on already saturated soil. The NIST-funded Center for Risk-Based Community ... -
A comparative evaluation of sepiolite and nano-montmorillonite on the rheology of cementitious materials for 3D printing
(Elsevier, 2022-10-03)Through the last decade, methods of digital manufacturing of concrete gained a significant interest compared to conventional concrete. The main challenge in additive manufacturing (3D printing) is to design a highly ... -
Comparison of blast analysis methods for modular steel structures
(Turkish Chamber of Civil Engineers, 2018-03)Two blast analysis methods widely used are three-dimensional finite element (FE) and uncoupled equivalent single degree of freedom (ESDOF) methods. The uncoupled equivalent ESDOF method, which is the most common blast ... -
A comparison study between 1D and 2D site response analyses based on observed earthquake acceleration records
(Springer, 2023)The objective of the present work is to evaluate the necessity of 2D site response analysis based on the comparison among the peak ground and spectral accelerations recorded by Istanbul Rapid Response Network and Istanbul ... -
A comparison study between 1D and 3D site response analyses based on observed earthquake acceleration records…
(National Technical University of Athens, 2023)The characteristics of the site conditions have a very significant influence on the variation of building damage during earthquakes, thus, it is essential to evaluate and analyse the effects of site conditions. One option ... -
Composite cold-formed steel rubberised concrete building framed systems
(Avestia Publishing, 2022)In this research, with the use of cold-formed steel (CFS) sections in-filled with rubberized concrete (RuC), a new low-carbon construction system is developed and assessed for its structural resilience and environmental ... -
A computational workflow for rupture‐to‐structural‐response simulation and its application to Istanbul
(Wiley, 2020-10)Scenario-based earthquake simulations at regional scales hold the promise in advancing the state-of-the-art in seismic risk assessment studies. In this study, a computational workflow is presented that combines (i) a ... -
A cost-benefit analysis of sensor quality and spatial density for rapid regional post-event seismic damage assessment: Application to Istanbul
(Elsevier, 2022-12)A quantitative evaluation of the influence of sensor quality and spatial density on the results of rapid regional seismic damage evaluations of buildings can provide an important reference for the deployment of a strong-motion ... -
Crack remediation in mortar via biomineralization: effects of chemical admixtures on biogenic calcium carbonate
(Elsevier, 2018-11-30)Limited research on biomineralization in cement-based systems suggested that self-healing of surface cracks could be obtained by triggering biogenic calcium carbonate (CaCO3) precipitation within the cracks. While this is ... -
