|Theory of Structures III
|This course focuses on the axial, shear, bending and torsion load-deformation response of continuous elastic prismatic structural elements such as rods, beams, shear walls, frames, arches, cables and rings. Additional special topics, such as the behavior of inelastic prismatic structural elements or the behavior of planar structural elements and structures, may be addressed time-permitting.
|After passing this course students will be able to:
1. Explain the equilibrium of continuous structural elements.
2. Formulate mechanical models of continuous prismatic structural elements.
3. Analyze the axial, shear, bending and torsion load-deformation response of prismatic structural elements and structures assembled using these elements.
4. Determine the state of forces and deformations in rods, beams, frame structures, arches, cables and rings under combined mechanical and thermal loading.
5. Use the theory of continuous structures to design structures and understand the basis for structural design code provisions.
|This is the third course in the ETH series on theory of structures. Building on the material covered in previous courses, this course focuses on the axial, shear, bending and torsion load-deformation response of continuous elastic prismatic structural elements such as rods, beams, shear walls, frames, arches, cables and rings. Additional special topics, such as the behavior of inelastic prismatic structural elements or the behavior of planar structural elements and structures may be addressed if time permits. The course provides the theoretical background and engineering guidelines for practical structural analysis of modern structures.

|Voraussetzungen / Besonderes
|Working knowledge of theory of structures, as covered in ETH course Theory of Structures I (Baustatik I) and Theory of Structures II (Baustatik II) and ordinary differential equations. Basic knowledge of structural design of reinforced concrete, steel or wood structures. Familiarity with structural analysis computer software and computer tools such as Matlab, Mathematica, Mathcad or Excel.
|Structural Dynamics and Vibration Problems
|B. Stojadinovic, V. Ntertimanis
|Fundamentals of structural dynamics are presented. Computing the response of elastic and inelastic single-DOF, continuous-mass and multiple-DOF structural systems subjected to harmonic, periodic, pulse, impulse, and random excitation is discussed. Practical solutions to vibration problems in flexible structures excited by humans, machinery, wind and explosions are developed.
|After successful completion of this course the students will be able to:
1. Explain the dynamic equilibrium of structures under dynamic loading.
2. Use second-order differential equations to theoretically and numerically model the dynamic equilibrium of structural systems.
3. Model structural systems using single-degree-of-freedom, continuous-mass and multiple-degree-of-freedom models.
4. Compute the dynamic response of structural system to harmonic, periodic, pulse, impulse and random excitation using time-history and response-spectrum methods.
5. Apply structural dynamics principles to solve vibration problems in flexible structures excited by humans, machines, wind or explosions.
6. Use dynamics of structures to identify the basis for structural design code provisions related to dynamic loading.
|This is a course on structural dynamics, an extension of structural analysis for loads that induce significant inertial forces and vibratory response of structures. Dynamic responses of elastic and inelastic single-degree-of-freedom, continuous-mass and multiple-degree-of-freedom structural systems subjected to harmonic, periodic, pulse, impulse, and random excitation are discussed. Theoretical background and engineering guidelines for practical solutions to vibration problems in flexible structures caused by humans, machinery, wind or explosions are presented. Laboratory demonstrations of single- and multi-degree-of-freedom system dynamic response and use of viscous and tuned-mass dampers are conducted.
|The electronic copies of the learning material will be uploaded to ILIAS and available through myStudies. The learning material includes: the lecture presentations, additional reading material, and exercise problems and solutions.
