Dear All,
Kindly, I wanted to perform several Non-Linear Time History Analyses in SAP2000 software on a single degree of freedom system by changing several parameters such as Time period, damping, and hysteresis curve parameters...
Is there any way to perform these analyses without running...
Respected All,
Hope you are doing well,
I wanted to design a shear wall which has a springs at its base , However for the sake of the simplicity, I just extract the highest force which may the springs apply on the shear wall , the next figure shows the FBD of the shear wall :
Where...
Respected All,
Hope you are doing well,
Kindly, I'm trying to design a shear wall in sap2000 to resist the earthquake load. As you may known that sap2000 doesn't have the option to design the shear wall so for this reason I'm using a wider column approach, where instead of modelling the...
Dear All,
Respected All hope you are doing well,
Kindly , I'm trying to understand how to derive the shape functions of Timoshenko beam using the concept of Virtual Work method. The theory is done on 3D beam element (Fig 1) .

Considering all...
Dear all,
I'm doing a linear static analysis of a 2d steel frame structure in order to get a displacement of the top joints due to lateral loads.
I want to model the uplifting of the column in this case to only allow the column to go up and not down. What I meant is that the support will only...
Dear All,
Hope you are doing well,
Kindly, I want to do a parametric analysis of SDOF under a harmonic forcing in order to get a force-displacement curve, would you please suggest me any software or reference about how to do that .
thank you,
Dear all,
Hope you are in the best condition of health,
I'm trying to find the damping coefficient (''C'') of an element of energy dissipation (Shear Fuses) with the next hysteresis loops and I do have also the back-bone curve would you please help with that,
Thank you your help is much...
Dear All,
Hope you are doing well,
I'm trying to model a type of energy dissipation element figure 01 ``Butterfly fuse ``, after a lot of research about the features of this device and how does it work, I could find the formulas of the strength and the stiffness for this device from the...
Dear All,
Hope you are all doing good,
I'm trying to model shear fuses (Picture 01) as an element of energy dissipation in my model ( they are added in order to dissipate the energy coming from the earthquake), however, I'm not able to find any explanation about how to model this element in...
Dear Fellow friends,
I'm doing a Response Spectrum Analysis for steel Structure (CBF Frame)in Etabs software, however, I'm trying to find the eigenvector noted as ''v'' of the first mode shape for the structure the one that we derive from the formula (K-w^2.M).v=0, I'm stuck in this part I...
Dear all,
I hope you are doing well,
I'm trying to model a post-tensioning bar in my structure in Etabs as is shown in the figure, unfortunately, I'm not able to find the option of modeling a post-tensioning strand in the software, I was thinking if I can model them as external Tendons if no...
Dear all,
Hope you are doing well, first I would like to thank you for your help and assistance with my question,
Basically, today, I have to main questions which are very important for me as well as a project that I'm working on,
1- I did a modeling four-building steel structure SCBF type in...

Dear all,
I'm designing 4 stories building steel structure on Etabs Software as you can see in the next Figure, however, I'm looking for the vectors of the first two-mode shapes of the structure in order to use them in one method that I'm using. the problem is when I look at the result I am...
Hello all,
hope you are doing well,
How to include the effect of bracings in the eigenvalue analysis of a single bay MDOF system?
My project is dynamic response control using shake table and I have attached bracings to the MDOF model and now I want to perform analytical calculations so I...
Hi everyone!!!!
Hope all of you are doing well.
I'm facing some problems with checking the crack in slab with ETabs , I have designed my building in Etabs and run analysis but I can't find the crack in slab option in Etabs , can some one help me !!!!
Thanks
