RISStrut-Relieved Single Steel Haunch Bracing System for Mitigating Seismic Damage of Gravity Load Designed Structures
Publisher: American Society of Civil Engineers
Abstract: A large number of existing reinforced concrete structures, constructed before the 197s, are poorly designed and inadequately detailed. The design and detailing of these structures are based on the prevailing guidelines and ...
Early Detection and Monitoring of Corrosion in Reinforced Concrete Structures Using Coupled Time-Frequency Analysis
Publisher: American Society of Civil Engineers
Abstract: Corrosion of steel rebar in reinforced concrete (RC) constructions is an issue of great concern toward ensuring the integrity of civil structures, and thus, detection of the on-set of corrosion process, if any, will ...
Virtual Frequency Fusion Technique: Detecting Multiple Damages via Broadband Lamb Wave Field Using Scanning Laser Vibrometry
Publisher: American Society of Civil Engineers
Abstract: This article presents an efficient frequency fusion method by virtual acquisition of multifrequency guided wave velocity data for robust and accurate localization of multiple damages in plate-like structures. Lamb waves ...
Performance Evaluation of a Stone Masonry–Arch Railway Bridge under Increased Axle Loads
Publisher: American Society of Civil Engineers
Abstract: Many of the masonry arch bridges in the network of railway bridge stock belong to the civil engineering heritage of the railways. Therefore, their maintenance and management require careful consideration. An effective ...
Marangoni Convection With a Curved and Deforming Free Surface in a Cavity
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A finite-volume based computational model is developed to predict Marangoni convection in a cavity with a curved and deforming free surface. The two-dimensional incompressible continuity, momentum, ...
Oblique Wave Scattering by a Symmetric Trench Submerged Beneath an Ice Cover
Publisher: ASCE
Abstract: A mathematical model of the interaction of an oblique wave and rectangular submarine trench in an ice-covered ocean is given using linearized potential theory. The motion in the fluid is characterized by velocity potentials, ...
Fuzzy Logic Based Condition Rating of Existing Reinforced Concrete Bridges
Publisher: American Society of Civil Engineers
Abstract: Fuzzy logic is a means for modeling the uncertainty involved in describing an event/result using natural language. The fuzzy logic approach would be particularly useful for remedying the uncertainties and imprecision in ...
An Improved Model for the Return to Isotropy of Homogeneous Turbulence
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In CFD modeling, the most widely used Reynolds stress models is the Speziale, Sarkar, Gatski (SSG) model. The present formulation, though similar in structure to the SSG model, is a mathematical variation assuming homogeneity ...
Health Assessment of a Plate Girder Railway Bridge under Increased Axle Loads
Publisher: American Society of Civil Engineers
Abstract: Most bridges are aging and do not have complete design information. Hence, field testing for the evaluation of the structural performance and health of bridges is becoming essential, but even sophisticated modern structural ...
Effect of Atmospheric Forcing on Plume Dispersion and Study of Nuclear Effluent Trajectories for the Kalpakkam Coast, India
Publisher: American Society of Civil Engineers
Abstract: The air–sea interaction process and its implication at the outfall location of a nuclear power plant have been studied using the Princeton ocean model (POM) under varied environmental forcing parameters (momentum and heat ...
