Using UAVs and Photogrammetry in Bathymetric Surveys in Shallow Waters
The use of UAV (unmanned aerial vehicle) platforms and photogrammetry in bathymetric surveys has been established as a technological advancement that allows these activities to be conducted safely, more affordably, and at ...
A cost-benefit analysis for the appraisal of social and market prices in the probabilistic seismic risk assessment of building portfolios: A methodology for the evaluation of disaster risk reduction programs
A cost-benefit analysis can be a milestone for the probabilistic seismic risk assessment of building portfolios. This approach appraises social, economic, and technical aspects as evaluation criteria, becoming a reliable ...
Applying Project-Based Learning (PBL) for Teaching Virtual Design Construction (VDC)
(International Association of Online Engineering, 2023)
Learning-centered models, which rely on active methodologies such as Project-Based Learning (PBL), should be adopted in undergraduate programs to potentiate the development of collaboration skills within future industry ...
Influence of Synthetic Fibers on the Flexural Properties of Concrete: Prediction of Toughness as a Function of Volume, Slenderness Ratio and Elastic Modulus of Fibers
The construction industry requires concrete with adequate post-cracking behavior for applications such as tunnels, bridges, and pavements. For this reason, polypropylene macrofibers are used, which are synthetic fibers ...
Integrating a LiDAR Sensor in a UAV Platform to Obtain a Georeferenced Point Cloud
The combination of light detection and ranging (LiDAR) sensors and unmanned aerial vehicle (UAV) platforms have garnered considerable interest in recent years because of the wide range of applications performed through ...
Experimental Volume Incidence Study and the Relationship of Polypropylene Macrofiber Slenderness to the Mechanical Strengths of Fiber-Reinforced Concretes
An experimental study was conducted to examine the mechanical strengths of concretes with straight high-strength knurled polypropylene macrofibers. Incidences of concrete mechanical strengths were determined for three ...
A Comparative Analysis of Production Metrics across VDC Implementations
(American Society of Civil Engineers (ASCE), 2022)
Production metrics (PM) are important yardsticks for AEC (Architecture, Engineering, and Construction) teams to determine whether their projects are on track. This paper reports on research that looked for empirical evidence ...
Exploiting HBIM for Historical Mud Architecture: The Huaca Arco Iris in Chan Chan (Peru)
The construction technique of raw earth, which has always been in use in most of the world, has left large monuments or architectural complexes to cultural heritage that need special attention due to the notable vulnerability ...
Virtual Design and Construction (VDC) Framework: A Current Review, Update and Discussion
Compared with other industries, construction has maintained one of the lowest growth rates in productivity and innovation over the last decades. Moreover, low compliance with schedule targets has remained a common issue ...
Determination of Polypropylene Fiber-Reinforced Concrete Compressive Strength and Elasticity Modulus via Ultrasonic Pulse Tests
Compressive strength and elasticity modulus are the main mechanical properties of concrete. The non-destructive ultrasound pulse test can be used to determine these properties without compromising the structure’s integrity. ...
