Earthquake Resistant Construction<br />
• <strong>Steel</strong> framed structures performed well during the <strong>Christchurch</strong><br />
• Inelastic/plastic deformation was less than predicted<br />
• A design philosophy is to have structural elements (eg. EBFs’)<br />
deforming plastically and absorbing energy<br />
• Some EBFs’ sustained significant plastic deformation<br />
• How much more plastic strain can these elements absorb?<br />
• The question is “to replace the deformed EBF or not to replace the<br />
deformed EBF” that is the question?<br />
• This aspect is examined in the Pacific Tower
