    SDOF in SAP2000

    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...

    Shear Wall Design

    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...

    Shear Wall design in Sap2000

    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...

    How to model a Special Support in SAP2000 ( Uplifting) ?

    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...

    Modelling the shear fuses ( Energy Dissipation Element)

    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...

    Eigen-Vectors of the mode shapes

    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...
