Introduction to seismic fitness

Published on

Abstract

The term Seismic fitness stands for ability of buildings or civil engineering structures to perform their basic operational functions with seismic risk limited to acceptable level. Seismic fitness may be considered the paramount goal of earthquake engineering which is concerned with protecting society, the natural and the man-made environment from the earthquake hazards.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Introduction

For any particular structural object and earth shaking intensity, ''seismic fitness'' is not universal. It depends on a particular type of challenge: e.g., the soil conditions, 3-D directions of shaking, possibility of tsunami and its magnitude, etc. Technically, earthquake engineering is the study of behavior of buildings and structures subject to seismic loading. To provide their seismic fitness, a structural engineer should: *Understand the interaction between buildings or civil infrastructure and the ground. *Foresee the potential consequences of strong earthquakes on urban areas and civil infrastructure. *Design, construct and maintain structures to perform at earthquake exposure up to the expectations and in compliance with building codes. A ''seismically fit'' structure does not necessarily has to be extremely strong or expensive. It just has to withstand the seismic effects while sustaining an acceptable level of damage. The most powerful and budgetary tools for upgrading ''seismic fitness'' of buildings and structures are vibration control technologies and, in particular, base isolation.

Earthquake Engineering Component

The goal of this activity is to help to better undersstand the basic principals and means of mitigation of damage from earthquakes and tsunamis. The contributor is a California lisenced engineer and research scientist in the field of earthquake engineering.
