Site response from Istanbul vertical arrays and strong motion network
(Earthquake Engineering Research Institute ( EERI ), 2014)In the framework of Istanbul Microzonation Project for the European side, the investigated region was divided by a grid system of 250m×250m and site investigations were performed for each cell based on borings and in-situ ... -
Site specific response analysis for performance based design earthquake characteristics
(Springer Science+Business Media, 2014-06)During strong earthquakes, seismic waves travelling towards the ground surface alter the engineering characteristics of the soil layers and consequently the characteristics of travelling seismic waves also change with ... -
Soil liquefaction and effects on structures; case study in Adıyaman-Gölbaşı after the 06 Feb 2023 earthquakes in Türkiye
(2023-11)On 06 FEB 2023, two earthquakes occurred southeast of Türkiye; Kahramanmaraş-Pazarcık (Mw=7.8) and Kahramanmaraş-Elbistan (Mw=7.6). These earthquakes caused devastating effects in 11 cities in eastern Turkey and northern ... -
Soil liquefaction-induced uplift of buried pipes in sand-granulated-rubber mixture: Numerical modeling
(Elsevier, 2022-03)The significant uplift of buried pipes observed during recent earthquakes has showed the need for further research in remediation methods for soil liquefaction. Sand-granulated rubber mixture is reported as a new soil ... -

Strip model for steel plate shear walls with beam-connected web plates
(National Technical University of Athens, 2019)Steel plate shear walls (SPSWs) are a lateral force-resisting system in which thin infill plates (web plates) are connected to the boundary frame (i.e., beams and columns) along four edges. Despite shear buckling of thin ... -
A suite of broadband physics-based ground motion simulations for the Istanbul region
(Wiley, 2023-04)Physics-based earthquake ground motion simulations (GMS) have acquired significant growth over the last two decades, mainly due to the explosive developments of high-performance computing techniques and resources. These ... -
Tension field inclination angle in steel plate shear walls with beam- connected web plates
(National Technical University of Athens, 2019)Steel plate shear walls (SPSWs) are an efficient lateral force-resisting system with thin infill plates, main elements resisting the lateral force, connected to beams and columns on all four edges. Upon lateral loading, ... -
Tracking major resources for automated progress monitoring of construction activities: masonry work case
(Emerald, 2021-10-21)Purpose: The purpose of this study is to monitor the progress of construction activities in an automated way by using sensor-based technologies for tracking multiple resources that are used in building construction. ... -
Two-part bio-based self-healing repair agent for cement-based mortar
(International Center for Numerical Methods in Engineering, 2020)Factors affecting durability of concrete structures are generally associated with each other. Due to its brittle nature, concrete can crack under stress and these cracks are one of the main reasons for a decrease in service ... -
Uncertainty in risk of highway bridges assessed for integrated seismic and flood hazards
(Taylor and Francis, 2017-11-24)Probabilistic risk assessment for bridges under natural hazards is of great interest to engineers for the development of risk mitigation strategies and implementation plans. The present study evaluates risk of an existing ... -
Use of biomineralisation in developing smart concrete inspired by nature
(Inderscience, 2015)Recently, interest has focused on leveraging the biological functions of microorganisms to develop smart cement-based materials. This paper provides an overview of the calcium carbonate biomineralisation process in nature ... -
Use of corn-steep liquor as an alternative carbon source for biomineralization in cement-based materials and its impact on performance
(Elsevier, 2018-03-20)Early age microcracks are generally the primary cause for a decrease in service life of cement-based structures. Recent studies suggested that it might be possible to develop a smart cement-based material that could self-heal ... -
Use of natural minerals to immobilize bacterial cells for remediating cracks in cement-based materials
(ASCE, 2022-03-01)Cracks in cement-based materials are one of the main factors affecting the durability of structure. Recent research in the field of concrete materials showed that self-healing in cement-based systems can be achieved by ... -
Use of pre-wetted lightweight fine expanded shale aggregates as internal nutrient reservoirs for microorganisms in bio-mineralized mortar
(Elsevier, 2017-11)Interest in developing bio-based self-healing cement-based materials has gained broader attention in the concrete community. One of challenges in developing bio-based self-healing cement-based materials is that cell death ... -
Velocity pulse effects of near-fault earthquakes on a high-speed railway vehicle-ballastless track-benchmark bridge system
(Taylor & Francis, 2022-09-02)The near fault (NF) line waves send out signal envelopes that oscillate over lengthy periods of time with periodic impulses. Like train bridges, train tracks demonstrate comparable track-bridge (TB) motion dynamics. Using ... -
Yumuşak zeminler üzerinde dolgu inşasında temel zemini göçmesine dayalı tasarım yaklaşımı
(TMMOB İnşaat Mühendisleri Odası, 2019-09)In order to tackle the difficulties encountered in embankment design and construction, a new design method for embankments on soft clays is proposed in this paper. The method approaches to the problem with the philosophy ...
