&lt;p&gt;Fyi, below image is the assignation of response spectrum in Z direction&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1691395875091v1.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;In my structure, I&amp;#39;ve purposely assigned one node (Node 9) between beam 5 &amp;amp; 9. (Refer to image below)&lt;/p&gt;
&lt;p&gt;And I&amp;#39;ve modelled beam 8 without midpoint node assigned to it.&amp;nbsp;&lt;span&gt;(Refer to image below)&lt;/span&gt;&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1691396064605v2.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;When I go to my beam result, noticed that there is Fz on beam 5 &amp;amp; 9 (Although beam 5 &amp;amp; 9 are actually one continuous beam)&lt;/p&gt;
&lt;p&gt;and&amp;nbsp;there is no Fz force on beam 8&lt;/p&gt;
&lt;p&gt;&lt;img style="max-height:240px;max-width:320px;" src="/resized-image/__size/640x480/__key/communityserver-discussions-components-files/5932/pastedimage1691396224212v3.png" alt=" " /&gt;&lt;/p&gt;
&lt;p&gt;&lt;/p&gt;
&lt;p&gt;Could anyone mind explaining it to me? Attached staad file for your reference.

My understanding on the truss system is that the diagonal, vertical &amp;amp; horizontal bracing are&amp;nbsp;subjected to axial force only.&lt;/p&gt;
&lt;p&gt;When I assigned all bracings as TRUSS member, it causes instability. Refer to this B2 staad model -&amp;nbsp;&lt;a href="/cfs-file/__key/communityserver-discussions-components-files/5932/B2.STD"&gt;B2.STD&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;When I assigned the diagonal and vertical bracing as TRUSS member only, the lattice truss beam has no issue. (Understand that the horizontal bracing must take moment at the end connections so that the overall structure is stable). Refer to this B1 staad model -&amp;nbsp;&lt;a href="/cfs-file/__key/communityserver-discussions-components-files/5932/B1.STD"&gt;B1.STD&lt;/a&gt;&lt;/p&gt;
&lt;p&gt;So which method of assignation is correct?&lt;/p&gt;
