Student Projects

Abstract

This study was conducted under the supervision of Prof. Sumusu Kono in the Tokyo Institute of Technology (TIT) and Prof. Katrin Beyer from the Earthquake Engineering and Structural Dynamics (EESD) laboratory in the Swiss Federal Institute of Technology in Lausanne (EPFL). This master thesis is preceded by a small pre-study project, where a general literature review on foundation piles subjected to earthquake and some preliminary models of various piles types have been done. The objectives of this pre-study was to learn correctly how to handle the finite element software Opensees1 and constitute some research background on the subject.

Earthquake engineering

Earthquake engineering is an interdisciplinary branch of engineering that designs and analyzes structures, such as buildings and bridges, with earthquakes in mind. Its overall goal is to make such structures more resistant to earthquakes. An earthquake (or seismic) engineer aims to construct structures that will not be damaged in minor shaking and will avoid serious damage or collapse in a major earthquake. A properly engineered structure does not necessarily have to be extremely strong or expensive.

Seismic loading

Seismic loading is one of the basic concepts of earthquake engineering which means application of an earthquake-generated agitation to a structure. It happens at contact surfaces of a structure either with the ground, or with adjacent structures, or with gravity waves from tsunami. Seismic loading depends, primarily, on: Anticipated earthquake's parameters at the site - known as seismic hazard Geotechnical parameters of the site Structure's parameters Characteristics of the anticipated gravity waves from tsunami (if applicable).

Seismic analysis

Seismic analysis is a subset of structural analysis and is the calculation of the response of a building (or nonbuilding) structure to earthquakes. It is part of the process of structural design, earthquake engineering or structural assessment and retrofit (see structural engineering) in regions where earthquakes are prevalent. As seen in the figure, a building has the potential to 'wave' back and forth during an earthquake (or even a severe wind storm). This is called the 'fundamental mode', and is the lowest frequency of building response.
