research overview

  • Dr. Liel's research program develops and applies novel methods for structural engineering design and assessment to improve the safety and sustainability of structures under extreme loads. Dr. Liel's research team creates complex nonlinear models of structural behavior in response to earthquake, snow and other loads to quantify the risk of collapse, damage or other outcomes of interest. These assessments result in probabilistic metrics of structural performance that provide the foundation for the development of innovative methods to identify vulnerable construction types or communities and to evaluate or improve design and mitigation strategies. Three central ongoing areas of research are: 1) collapse risk and retrofit strategies for older potentially dangerous concrete buildings, 2) effects of liquefaction on building structures and tradeoffs associated with mitigation and 3) effects of induced earthquakes on buildings and infrastructure.

Teaching

courses taught

  • CVEN 3227 - Probability, Statistics and Decision
    Primary Instructor - Spring 2021 / Spring 2022
    Introduces uncertainty based analysis concepts and applications in the planning and design of civil engineering systems emphasizing probabilistic, statistics, and design concepts and methods.
  • CVEN 4525 - Computational Structural Analysis 1
    Primary Instructor - Fall 2020
    Covers the principles and formulations of the direct stiffness method and its transition to the finite element method with the computational modelling and analysis of framed structures in 2D plane and 3D space. The dynamic analysis and the introduction to the nonlinear structural problems are provided. Familiarity with the modern computing and programming environments is increased to address the needs in the structural engineering and mechanics area. Computer programming is applied to the solution of problems in structural analysis. Same as CVEN 5525.
  • CVEN 4555 - Reinforced Concrete Design
    Primary Instructor - Fall 2018 / Fall 2019 / Fall 2021 / Fall 2023 / Fall 2024
    Applies basic principles of structural engineering and mechanics to the design of reinforced concrete structures, including design of beams, columns, slabs, and footings; continuous beams and frames; cast-in-place buildings.
  • CVEN 4899 - Civil Engineering Senior Project Design
    Secondary Instructor - Spring 2020 / Spring 2021
    Provides a simulated real world design and construction planning experience where teams integrate across multiple civil engineering sub-disciplines to create a solution that satisfies multiple constraints, including design, client requirements, budget, schedule, technical, regulatory, and societal. Final deliverables include: detailed design drawings, specifications, cost estimate, project schedule, construction plan, oral and written presentation.
  • CVEN 5111 - Structural Dynamics
    Primary Instructor - Fall 2023 / Fall 2024
    Focuses on the response of single- and multi-degree of freedom structures subjected to harmonic, impulsive and arbitrary loads (including earthquake base excitation). Sources and modeling of damping will be discussed. Analytical and numerical solutions will be considered for both linear and nonlinear structural systems. Elastic and inelastic response spectra will be discussed.
