Relationship between response modification coefficient and displacement amplification factor for different seismic levels and site classes
(National Technical University of Athens, 2019)Modern seismic design provisions allow structural systems to be designed for reduced forces, which are typically much smaller than the corresponding elastic design loads. This reduction in seismic loads is done by using ... -
A rule-based methodology for automated progress monitoring of construction activities: A case for masonry work
(International Council for Research and Innovation in Building and Construction, 2019)The conventional approach that is used to monitor construction projects is to collect progress data from the construction site through visual investigation. This results in deficient and sometimes erroneous data, and leads ... -
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 ... -
Influence of Sporasarcina pasteurii cells on rheological properties of cement paste
(Elsevier, 2019-11-20)Nowadays with the developments in the concrete materials technology, researches started to focus on highly flowable mixes with improved rheological properties. These highly flowable mixes generally require use of viscosity ... -
Bacteria-based concrete
(Elsevier, 2018)Several strains of bacteria can induce the precipitation of calcium carbonate, if the appropriate conditions, sufficient nutrients and a calcium source are provided. The metabolic pathway that is followed by the bacterial ... -
Analyzing the benefits and challenges of building information modelling and life cycle assessment integration
(IEEE, 2020)Previous studies show that the architecture, engineering and construction (AEC) industry contributes up to 1/3 of global GHG emissions. With the aim of mitigating negative impacts of AEC industry on the natural environment, ... -
Mixed method review for integrating building information modeling and life-cycle assessments
(Elsevier, 2020-04-15)Previous studies have suggested that building information modeling (BIM) and life-cycle assessments (LCAs) could be integrated to quantify and alleviate the environmental effects of buildings while simplifying and optimizing ... -
Pros and cons of using building information modeling in the aec industry
(American Society of Civil Engineers, 2019-08-01)Although a plethora of studies on building information modeling (BIM) have been conducted in the last decade, none of the previous studies collate and/or prioritize the benefits, risks, and challenges of BIM based on the ... -
Behavior of columns of steel plate shear walls with beam-connected web plates
(Elsevier, 2018-10-01)Steel plate shear walls with beam-connected web plates (B-SPSWs) are an alternative configuration of steel plate shear walls (SPSWs) where web plates are connected to the beams only. Detaching web plates from columns and ... -
Energy-based sidesway collapse fragilities for ductile structural frames under earthquake loadings
(Elsevier, 2018-11)In assessing the likelihood of structural collapse under strong earthquake motions, uncertainties in structural properties and ground motions can be incorporated by use of a probabilistic analysis framework in conjunction ... -
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 ... -
Implications of site specific response analysis
(Springer, 2018)Definition of design earthquake characteristics, more specifically uniform hazard acceleration response spectrum, on the ground surface is the primary component for performance based design of structures and assessment of ... -
A simplified approach for site-specific design spectrum
(Springer, 2018)The design acceleration spectrum requires site investigations and site-response analyses in accordance with the local seismic hazard. The variability in earthquake source and path effects may be considered using a large ... -
Evolution of seismic hazard maps in Turkey
(Springer International Publishing, 2018-08)A review on the historical evolution of seismic hazard maps in Turkey is followed by summarizing the important aspects of the updated national probabilistic seismic hazard maps. Comparisons with the predecessor probabilistic ... -
Seismic design and performance of SPSWs with beam-connected web plates
(Elsevier, 2018-03)Steel plate shear walls with beam-connected web plates (B-SPSWs) are an alternative steel plate shear wall (SPSW) configuration in which the web plate edges are detached from the columns to avoid high flexural demands in ... -
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 ... -
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 ... -
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 ... -
Nonlinear dynamic behavior of the basins with 2D bedrock
(Elsevier, 2018-04)Resonance due to impedance contrast, focusing due to subsurface topography, conversion of the body waves to surface waves and subsurface topography are among the factors influencing the amplification specification of the ... -
Impact spectrum of flood hazard on seismic vulnerability of bridges
(Techno-Press, 2018-05-25)Multiple hazards (multihazard) conditions may cause significant risk to structures that are originally designed for individual hazard scenarios. Such a multihazard condition arises when an earthquake strikes to a bridge ...
