Ressalta-se que a carga crítica é encontrada quando a frequência de vibração se anula (&lt;del class=&quot;diffchange diffchange-inline&quot;&gt;&amp;amp;#x03c9; &lt;/del&gt;= 0). Dessa forma, para uma ligação com rigidez &lt;del class=&quot;diffchange diffchange-inline&quot;&gt;&amp;amp;#x03b3; &lt;/del&gt;=&lt;del class=&quot;diffchange diffchange-inline&quot;&gt; 0&lt;/del&gt;, obteve-se a carga crítica de 980.561 kN. Conforme a rigidez da ligação aumenta, o sistema torna-se evidentemente mais rígido, e a frequência natural também sofre um pequeno acréscimo de 4.061 Hz para 4.657 Hz. Como esperado, as cargas críticas para ligações mais rígidas são mais elevadas.

Essa análise foi realizada supondo o solo representado através do modelo de Winkler (&amp;lt;&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;math display=&amp;quot;inline&amp;quot;&lt;/ins&gt;&amp;gt;&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;k_1&lt;/ins&gt;&amp;lt;/&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;math&lt;/ins&gt;&amp;gt;= 2.068 MN/m&amp;lt;&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;math display=&amp;quot;inline&amp;quot;&lt;/ins&gt;&amp;gt;&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;^&lt;/ins&gt;2&amp;lt;/&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;math&lt;/ins&gt;&amp;gt; e &amp;lt;&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;math display=&amp;quot;inline&amp;quot;&lt;/ins&gt;&amp;gt;&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;k_2=0&lt;/ins&gt;&amp;lt;/&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;math&lt;/ins&gt;&amp;gt;). Ressalta-se que a carga crítica é encontrada quando a frequência de vibração se anula (&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;&amp;lt;math display=&amp;quot;inline&amp;quot;&amp;gt;\omega &lt;/ins&gt;=0&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;&amp;lt;/math&amp;gt;&lt;/ins&gt;). Dessa forma, para uma ligação com rigidez &lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;&amp;lt;math display&lt;/ins&gt;=&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;&amp;quot;inline&amp;quot;&amp;gt;\gamma =0&amp;lt;/math&amp;gt;&lt;/ins&gt;, obteve-se a carga crítica de 980.561 kN. Conforme a rigidez da ligação aumenta, o sistema torna-se evidentemente mais rígido, e a frequência natural também sofre um pequeno acréscimo de 4.061 Hz para 4.657 Hz. Como esperado, as cargas críticas para ligações mais rígidas são mais elevadas. O valor da carga crítica obtido para uma ligação perfeitamente rígida (&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;&amp;lt;math display&lt;/ins&gt;=&lt;ins class=&quot;diffchange diffchange-inline&quot;&gt;&amp;quot;inline&amp;quot;&amp;gt;\gamma = 1&amp;lt;/math&amp;gt;&lt;/ins&gt;) foi de 3886.142 kN. Nota-se boa concordância das respostas obtidas neste trabalho com os resultados encontrados na literatura.&lt;/div&gt;&lt;/td&gt;&lt;/tr&gt;
