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...
Dear MotorCity,
Yes the spring will be acting in tension when the lateral load will applied while the other one will in compression, Nevertheless, the two springs are already designed ,I'm left with reinforcement in the shear wall, I'm confused about the section that should resist the tension...
Dear Mr Greenalleycat,
Thank you for your kind reply, the spring is called a ring spring , this device is installed in the structure to provide a self-centering when earthquake load will occur, this spring element will dissipate 60 % of the applied load (Earthquake Energy) through the friction...
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...
Thank you Sir for your reply,
Would you please elaborate more in your answer because I'm new in this topic. your help is much appreciated .
Thank you looking forward for your reply.
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 Mr Retrograde ,
Thank you for your reply, I guess the solution that you suggest is perfect my mine issue now how to find the value of K and C, the stiffness and Coefficient of Damping respectively, the only information that I have is energy dissipation ratio β= 0.25.
Could you please...
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...
