<r>Hi Adeel,<br/> As you suggested, I read all the documents, and draw bi-linear idealized capacity curve.<br/> I found the all the properties for Takeda element as follows.<br/> Yield force = 114.15 kN<br/> Initial stiffness (sy) = 15230.42 kN/m<br/> Post yielding to initial stiffness ration = 0.05...

<r>Hi Adeel,<br/> Thank you very much for your help, please see the excel sheet for the capacity curve.<br/> In Takeda link elemen, I should provide the Yielding force- 97kN, and the Initial stiffness should be form Idealized bi-linear capacity curve post yield stiffness, is it right?<br/> <br/> <UR...

<r>Hi Adeel,<br/> Thank you very much for your reply. I performed the pushover analysis, and when the reinforcement is yielding at that time the yield force is 97kN, but how do we find the initial stiffness ? Initial stiffness = initial force/ initial deformation ?<br/> But, I dont know how do we fi...

<r>Hi Adeel,<br/> Thank you very much for your reply. I am running static time history analysis.I restrained the second node of the link which is the first node of column. The first node of the link was restrained only y+rx+rz. The load I applied to the top of the column with axial mass, and lateral...

<r>I am analyzing a RC circular concrete column for static time history analysis. For the stiffness degradation I used Takeda Link element for the static time history analysis.<br/> I am getting base shear and displacement, but not getting force in the Link element.<br/> As per the previous discussi...

<t>Dear SeismoSoft Support Team,<br/> Thank you very much for your kind response to my earlier query.<br/> I would like to ask you that, I calculated the confinement pressure (fl)for FRP using this equation (for entire circumference of circular section)<br/> <br/> fl= tfrp.n.Efrp.efrp/d, <br/> <br/>...

<t>Hi there,<br/> I am modelling CFRP-jacketed circular RC cantilever column. I applied quasi-static cyclic time history load at the tip of the column along with constant lumped mass at the top of the column. I used the Taked link element for the stiffness gradation.<br/> <br/> The as built column e...

<t>Dear SeimoSoft Team,<br/> Thank you very much for your reply. As you suggested, I try with Takeda, and Lin_Sym, both individually, there is no change in load carrying capacity and stiffness in initial drift ratio of CFRP jacketed column with compared to as built column. I sent an email to you wit...

<t>Hi there,<br/> Thank you very much for your kind response to my query. As you recommended, I replaced the Takeda curve and used the lin_sym, but there is no any change on load carrying capacity or stiffness, only the load increased 0.58 kN.<br/> I again modeled, without the link element, even the...

<t>Hi,<br/> I am modelling a CFRP retrofitted cantilever circular RC columns with displacement control quasi-static time history load with constant lumped mass at the top of column. The as-built column was model without the CFRP jacket while the other specimen is modeled using one, two, three and fo...
