Ballistic Impact Simulations using the new Unified Mechanics Theory
(State University of New York at Buffalo, 2018)
Ballistic Impact is a high velocity impact on a target by a projectile having a small mass and size. The aim of this thesis is to study ballistic impact using the new Unified Mechanics Theory. Numerical simulation of ...
Wave Motion in 1-D Viscoelastic Phononic Crystals: A Comprehensive Analytical, Numerical and Experimental Study
(State University of New York at Buffalo, 2018)
Phononic crystals are engineered materials which exhibit unique wave motion properties due to periodic arrangement of multiple homogeneous constituents. Over the last decade, metallic phononic crystals have been thoroughly ...
Enabling Full-Scale Soil-Structure Interaction Modeling through Analysis of a Geotechnical Laminar Box and Real-time Dynamic Hybrid Simulation
(State University of New York at Buffalo, 2019)
Soil-structure interaction is broadly assumed to be beneficial, with the incorporation of a flexible soil resulting in period-lengthening of the soil-foundation-superstructure system. However, this a high-level product and ...
EVALUATION OF SITE RESPONSE, WITH APPLICATION TO NUCLEAR STRUCTURES
(State University of New York at Buffalo, 2019)
Nuclear power plants (NPPs) and other safety-related nuclear facilities offer unique design challenges not encountered with commercial infrastructure. One such challenge is the characterization of the effects of soil-structure ...
CORROSION MITIGATION IN REINFORCED CONCRETE STRUCTURES USING ENGINEERED CEMENTITIOUS COMPOSITES
(State University of New York at Buffalo, 2019)
Concrete is the most widely used construction material in the world. However, approximately 10% of the bridges in the United States, majority of which are made of reinforced concrete, are structurally deficient or functionally ...
A MULTISCALE STUDY OF CONCRETE SUBJECTED TO ELEVATED TEMPERATURES
(State University of New York at Buffalo, 2019)
Low aspect ratio, shear-critical, reinforced concrete walls are used in nuclear power plants to resist gravity and lateral forces, and some serve a containment function. Beyond design basis earthquake shaking has the ...
Structural Health Monitoring using Unsupervised Learning Methods with a view on Post-Earthquake Damage Detection
(State University of New York at Buffalo, 2019)
In a world of aging infrastructure, structural health monitoring (SHM) emerged as a major step towards resilient and sustainable societies. As we live in the information age, the advancements in machine learning and sensor ...
Selection and Scaling of Ground Motions for Generating In-structure Floor Spectra in Nuclear Power Plants
(State University of New York at Buffalo, 2019)
Response-history analysis has become a widely used tool for design and performance assessment of structures, systems and components. Prior to such analysis, an engineer is required to select and scale earthquake ground ...
Reducing Earthquake-induced Damage to Precast Concrete Bridge Piers
(State University of New York at Buffalo, 2019)
Precast concrete is under-utilized in seismic regions. This dissertation will discuss methods for reducing earthquake-induced damage to precast concrete piers to enable deployment of accelerated construction in the regions ...
FLEXURAL BEHAVIOR OF HIGH-STRENGTH CONCRETE SLENDER WALLS – ANALYTICAL STUDY
(State University of New York at Buffalo, 2019)
The use of reinforced concrete structural walls is very common for resisting lateral forces induced by earthquakes and wind, particularly in medium-rise to high-rise buildings.They provide vertical continuity in the ...
