Advancements in bender-element testing - frequency effects
(University of Waterloo, 2019-09-24)Modern building and bridge codes require seismic design of foundations and structures; for which, the evaluation of the soil’s response to dynamic loads is an important requirement in seismic design. The dynamic soil ... -
Analysis of Passive Magnetic Inspection Signals Using the Haar Wavelet and Asymmetric Gaussian Chirplet Model (AGCM)
(University of Waterloo, 2022-04-07)Nowadays, Non-Destructive Testing (NDT) techniques are an essential foundation of infrastructure retrofit and rehabilitation plans, mainly due to the huge amount of construction, as well as the high cost of demolition and ... -
Condition Assessment of Concrete Elements through Two Nondestructive Ultrasonic Techniques
(University of Waterloo, 2017-07-13)Reinforced concrete is one of the materials most used in civil infrastructure, and the expected service life is generally for several decades. However, as any other material, concrete performance is affected by environmental ... -
Excitation Force and Frequency Effects in Wave-Based Techniques for the Characterization of Geomaterials at Different Scales
(University of Waterloo, 2020-10-06)All around the world, building codes require the characterization of geomaterials as a fundamental step in the foundation design process. Specifically, in seismic design, the evaluation of dynamic properties is a key ... -
Experimental Evaluation of a Distributed Fiber Optic Sensor for Mining Application
(University of Waterloo, 2016-05-04)Triggered remote seismic events have been widely studied in the earthquake engineering context where various possible explanations have been provided, including directivity of dynamic stresses, a critically stressed ... -
Non-destructive Evaluation of Damage in Concrete with Applications in Shallow Foundations
(University of Waterloo, 2018-09-25)The most widely used material for civil infrastructure is reinforced concrete. The concrete deteriorates over time because of several reasons, and therefore, inspection of concrete is necessary to ensure its compliance ... -
