Actually I am trying to model a deteriorated 2D RC frame structure under seismic loads and I am taking the joint modeling into consideration. Therefore, at the interface of the beam\column-joint, there are two rotational springs in series. One to account for the corrosion effect on the...

Thank you very much for you help. Could you please provide me with an example for such integration?. What I do not get is how I should integrate the whole moment-curvature curve over the plastic hinge length to get the moment-rotation curve.

What is the difference between moment-rotation relationship and moment-curvature relationship for a structural element (e.g. beam, column)? Also, How to convert the moment-curvature which is calculated from the sectional analysis to moment-rotation relationship or the other way around? Thank...

Dear All, I have some questions regarding the use of the joint element formulation and the calibration procedures. Firstly, regarding the calibration procedure for the bond slip response, from where should  I get the bar stress (fs) that will be used to get the bar stress vs. bar slip and...

Hi everyone, I have questions that I hope someone will help me in answering them. 1) is it effective to place a plain viscous damper for vertical mid-span vibrations when located to act horizontally at the roller support of a simply supported beam? 2) why would the periods of the first modes...
