Question: Dear Professor Banerji, I am going through your lectures and currently I am in lecture 7. I am confused about the complex planes and why u(t)= rho*sin(omegabar*t-theta) was plotted in complex plane. Also I am confused about angles taken from complex axes, and some from real axis as in R.Clough boo By: Rohit     Date: 2012-07-12

Question: Sir, I have attended lecture 6 and & where mostly the Argand diagram is discussed. All went well. But one thing I couldn't make out is the practical or physical significance of the Argand diagram. Specially incase of resonance and theta greater than 90 degree. I cant write more though I wish to.

Question: At the two problems solved, the damping taken as zero and this is not true because the transient motion wouldn't completely decay. By: Ashraf Nayel     Date: 2012-09-29

Question: sir can u please tell how to find the solution of a non linear equation of motion using newmarks method. For example for the given equation of motion { mu''+Function(u)=P(t) }, where Function(u) is spring force which in not a linear function of displacement, is to be solved using newmarks method By: sonu     Date: 2012-10-03

Question: Respected sir ,myself is tousif ahmed b.tech(civil),i wanted to know how we generate individual floor spectra from whole structural response spectra as per IS code,because some floor extra floor newly added and i wanted to locally analys that particular floor.

Question: Dear sir, Is there any videos on Laboratory experiments covered in this course, as you told in few lectures at the beginning of the course. By: E Ramkumar     Date: 2013-01-06

Question: In the 3-storey example: With mode #1, I assumed phi1= 1.0 (which made phi2= 2 and phi3= 3). In the video, the mode shape is 0.6375, 1.2750, 1.9125. How was this normalized? I have not been able to replicate it after many attempts. grant.horeczy@deereault.com By: Grant H     Date: 2013-03-16
