Design and analysis of concentrically braced steel frames under seismic loading
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)The lateral resistance of many steel framed structures is provided by diagonal brace members and their connections to the frame. Although concentrically braced frames (CBFs) are common throughout international design ... -
Investigation on autonomous healing for GFRP composite using cyanoacrylate adhesives
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2012)An investigation into smart structures with a vascular healing system using cyanoacrylate (CA) adhesive is presented in this thesis. The flexibility in the functional role of a smart structure involves the structure executing ... -
Short-term traffic condition variables forecasting using Artificial Neural Networks
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2013)Short-term traffic forecasting (STTF) is a critical element of Intelligent Transport Systems (ITS). The use of ITS is vital in order to ensure the sustainability and increase the efficiency of the transportation network. ... -
Performance of high-strength concrete composite columns subject to earthquake loading conditions
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2011)Composite construction has been used in industry for decades due to superior load carrying capacity of the members compared with traditional reinforced concrete construction. A composite column is a structural member that ... -
An investigation into the causes, impacts and measures to deal with diatom bloom in Vartry Reservoir
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2019)In Ireland, there are more than 12,000 lakes and lakes and reservoirs are the main source of drinking water for two million people. Consisting of upper lake and lower lake, Vartry Reservoir is a key drinking water source ... -
Modification, practical application and numerical study of air-cathode microbial fuel cells
(Trinity College Dublin. School of Engineering. Disc of Civil Structural & Environmental Eng, 2019)Microbial fuel cell (MFC) technology has been attracting great attention recently due to its potential for simultaneously harvesting electric energy, removing pollutants and monitoring organic matter concentration at ... -
Semi-active vibration control of wind turbine blades using a time-frequency approach
(Trinity College (Dublin, Ireland). Department of Civil, Structural and Environmental Engineering, 2010)This thesis proposes the use of structural control devices to mitigate the response of wind turbines, particularly the blades.
