101-0188-00LSeismic Design of Structures I3 credits2GA. Tsiavos
AbstractThe following topics are covered: 1) origin and quantification of earthquake hazard; 2) seismic response of elastic and inelastic structures; 3) response history and response spectrum seismic evaluation methods; 4) basis for seismic design codes; and 5) fundamentals of seismic design of structures. These topics are discussed in framework of performance-based seismic design.
ObjectiveAfter successfully completing this course the students will be able to:
1. Explain the nature of earthquake hazard and risk.
2. Explain the seismic response of simple linear and nonlinear single- and multi-degree-of-freedom structural systems and quantify it using response time history and response spectrum approaches.
3. Apply design code provisions to size the structural elements in a lateral force resisting system of a typical frame and wall buildings.
ContentThis course initiates the series of two courses on seismic design of structures at ETH. Building on the material covered in the course on Structural Dynamics and Vibration Problems, the following fundamental topics are covered in this course: 1) origin and quantification of earthquake hazard; 2) seismic response of elastic and inelastic single- and multiple-degree-of-freedom structures; 3) response history and response spectrum seismic response evaluation methods; 4) basis for seismic design codes; and 5) fundamentals of seismic design of structures. These topics are discussed in framework of performance-based seismic design.
Lecture notesElectronic copies of the learning material will be uploaded to ILIAS and available through myStudies. The learning material includes the lecture presentations, additional reading, and exercise problems and solutions.

Prerequisites / NoticeETH Structural Dynamics and Vibration Problems course, or equivalent. Students are expected to be able to compute the response of elastic single- and multiple-degree-of-freedom structural systems in free vibration, as well as in forced vibration under harmonic and pulse excitation, to use the response spectrum method, and to understand and be able to apply the modal response analysis method for multiple-degree-of-freedom structures. Knowledge of structural analysis and design of reinforced concrete or steel structures under static loads is expected. Familiarity with general-purpose numerical analysis software, such as Matlab, and structural analysis software, such as Cubus, Sofistik or SAP2000, is desirable.
101-0194-00LSeismic Evaluation and Retrofitting of Existing Buildings2 credits1GA. Tsiavos
AbstractThe aim of this course is to present the state of the art of the current procedures for seismic evaluation and retrofitting of existing buildings in Switzerland (Norm SIA 269/8) and worldwide. Emphasis will be given on the practical application of these procedures in real buildings located in Switzerland, through case studies presented by experts in the field.
ObjectiveA large percentage of the existing building inventory worldwide has been constructed before the introduction of the current seismic code provisions. The seismic deficiencies observed in many of these structures are a direct outcome of their non-compliance with these provisions and the established engineering practices in seismic design. Moreover, the unavoidable material deterioration in these structures could further inhibit their seismic performance. Therefore, the knowledge of the current procedures and common practices for the seismic evaluation and retrofitting of buildings is of paramount importance. This course presents an overview of these procedures through a wide spectrum of applied case studies in Switzerland and worldwide. The students will work on a project related to the presented case studies, thus obtaining deep understanding on the application of these procedures and a feeling on how to engineer practical retrofitting strategies towards the seismic upgrading of existing buildings.
Content1. Introduction to seismic hazard and seismic performance objectives.
2. Common structural deficiencies and observed damage patterns in buildings due to strong earthquake ground motion excitation.
3. Seismic evaluation of buildings in Switzerland using Norm SIA 269/8: Presentation of the code in steps and discussion of the critical issues.
4. Seismic retrofitting of buildings in Switzerland using Norm SIA 269/8: Presentation of the code in steps and discussion of the critical issues.
5. Application of seismic evaluation using SIA 269/8 on an existing building in Switzerland.
6. Application of seismic retrofitting using SIA 269/8 on an existing building in Switzerland.
7. Seismic evaluation methodologies worldwide: State of the art. Presentation of illustrative examples.
8. Introduction to Yield Point Spectra and the Constant Yield Displacement Evaluation (CYDE) method.
9. Seismic retrofitting strategies worldwide: State of the art. Presentation of illustrative examples.
Prerequisites / NoticeThe attendance of the course Existing Structures (Erhaltung von Tragwerken-101-0129-00L) and the participation in the course Seismic Design of Structures I (101-0188-00L) in parallel with this course are highly recommended.
