Our futuristic vision for Sustainable and Resilient Structures is one that has transparent expectations of structural performance against time, increased loads, environmental changes and natural disasters. Our goal is to adapt quickly to new circumstances and prepare for future and uncertain threats.
Under extreme single or multi-hazardous events, such as earthquake sequences of foreshocks, mainshocks and aftershocks or/and sequential strong wind loading, the safety margins of structures can be exhausted quickly. The sudden failure of individual components and their uncontrolled interaction with the adjacent elements can trigger significant structural instabilities in both local and global level thus leading the structure to unexpected partial or total collapse.
This research aims to investigate the collapse mechanisms of existing older steel structures under multi-level hazard loads and deformations and propose a new retrofitting technology. Main goals are: a) development of a computational platform for simulating accurately the collapse of structures by combining efficiently both advanced analytical methods and experimental technologies; b) evaluation and quantification of the ultimate capacity of structures and their failure mechanisms determining the actual ductility margins and fatigue resistance. The final goal of the present research is the development of a sustainable retrofit technology that brings the structures up to current or future safety standards with the minimum cost and disturbance.
The Department of Civil Engineering welcomes applications from excellent students with a strong background in structural dynamics, wind and earthquake engineering. A good knowledge of finite element analysis methods (e.g., ABAQUS) and programming languages (e.g., MATLAB) are essential. Basic understanding/experience of laboratory procedures and experiments are desirable.
