Seismic Design of Structures I

Abstract

Introduction to fundamentals of earthquake engineering: 1) Elements of seismology, response spectra and ductility. 2) Conceptual seismic design. 3) Seismic analysis of buildings by means of established linear code procedures; i.e. equivalent lateral force and response spectrum methods. 4) Design and detailing of buildings with emphasis on the capacity design of reinforced concrete structures.

Objective

During the course the students shall learn the: 1) Fundamentals of earthquake engineering. 2) Seismic design of simple structures. 3) Peculiarities of the design for a dynamic action compared to a purely static action (interaction between the action and the structural response)

Content

1) Elements of Seismology: Origin of earthquakes, seismic waves, characterization of the earthquake ground motion, magnitudes and intensities, attenuation relationships. 2) Response spectra and ductility: Time-history analysis of linear and nonlinear single-degree-of-freedom (SDOF) systems, elastic and inelastic response spectra, strength and ductility, design spectra. 3) Conceptual seismic design: General characteristics of buildings, adequate structural systems, basic principles of seismic conceptual design. 4) Analysis methods: Overview of different analysis methods, elements of structural dynamics, equivalent lateral force method, response spectrum methods. 5) Seismic analysis of buildings: Modeling of the building (adequate structural models, stiffness estimation, period of vibration, …), computation of the sectional forces, distribution of the base shear to the different structural elements. 6) Design and detailing of buildings: Nonlinear reinforced concrete sectional analysis, the capacity design method, capacity design of structures, non-structural elements.
