Subject: Fwd: {4738418}: creep summation
Body:
<!--html--><br>
Dear Mr. Devan, <br>
<br>Apologies for the extended delay. <br>
<br>Lets look how the software considers Creep primary and Creep secondary.<br>
<br>
<img src="http://globalsupport.midasuser.com/helpdesk/GetAttachment.ashx?FileID=3118065"><br>
<br>ϵcr:  Creep strain (time-dependent strain due to creep)<br>
<br>  P:  Fictitious member force required to induce Creep strain (CS: Creep Primary)<br>       Computing the fictitious force is necessary in the process of finding the creep strain, which is expressed     in terms of member forces. This however has no physical meaning.<br>  ∆: Deformation due to Creep accounting for the constraints (CS: Creep Primary)<br>  F: Member force due to Creep accounting for the constraints (CS: Creep Secondary) <br>  R1, R2: Reactions due to Creep accounting for the constraints (CS: Creep Secondary)<br>
<br>
<br>
<br>While considering the deformations, creep primary has to be included. <br>But for forces this load combination should not be considered, but instead just the creep secondary forces are to be considered. <br>
<br>Hope this resolves your query. Do contact for any further clarification. <br>
<br>Thanks and Regards,<br>Sindhu Bharathi N J<br>Technical Support Engineer <br>MIDAS Information Technology Co., Ltd.<br>

<b><span style="color: black">Midas Hello<br>
</span></b><b><span style="color: black">When using the construction stage analysis, I understand that the effect of creep on displacements is taken into account and can be seen in the summation for each stage<br>
</span></b><b><span style="color: black">When viewing resuls on the post C/S model, if I want to check my displacements, considering creep, do I need to add "creep primary" to my combination? If so will these creep primary forces not distort my force results?<br>
