JazakAllah May Allah bless you. Thank you so much for these lectures. Much needed.

Thank you very much for such explanation, My question is here: If a structure is designed based on (R & Omega), then the structure will not resist a seismic force equal to V_elastic, because we will not reach point A through path OBC. Does this mean the structure is under design?

Brilliant way of Explanation. Thanks a Lot Sir, this made the basic concepts more clear.

Respected sir : what if the calculated design base shear from RSA is greater than the base shear from static Method (ELF)? so, is there any need to equalize (match) base shear from both the methods? or just take base shear from RSA?

Sir can you make a video how to find mode shapes of a framed model set on shake table ( ie harmonic excitation to base). Including the effect of damping

when does DSHA become less conservative that the PSHA?

Sir ya urdu language ma lecture ha?

thanks for clearing the concept, i was not picking up what is the diff between pga and Sa(T1) before this lecture

sir, can you plz provide detail discussion about how we can convert nonlinear MDOF to equivalent SDOF system

Sir EQ loading may cause torsion in building, the same effect is created by wind loading. so both have same natures.

Sir, thanks a lot for sharing these valuable informations with very clear explanations!

Salute you sir. Very informative and properly explained the concept of spectral acceleration, response spectrum and THA.

Nice try. But Dr Javid is on another level.

"Those people are gonna d!e up there if something's not done. I blame TJ Dettwiler for this!"

The efforts generated by the spectrum in the structure are absolute values, which cannot be combined with gravitational loads (which have a sign convention according to the direction of the force). How can you give a sign to the forces generated by the spectrum and be able to combine them with gravitational charges and so on?

Why in Mdesign equation, R is not divided by I like the base shear equation

can we assume (x/L)^2 as a shape function on those example from AK chopra , what are other condition which may affect on selecting the shape funciton except boundary condition??

how do we decide a push over displacement in a four storey building?

thankyou so much sir

Thank you sir for these lectures

Michael O'Halloran's superior in this is Principal Prickley. Prickley's counting on O'Halloran to save the day!

Hello professor, At time 7:40, you talk about some exception and site specific ground motion procedure, my model have S1 >0.2 and Time period, T <Ts, site class E（ which lies in the set 3 and also in the 3rd category of exceptions). The which method I need to use, chapter 11, or chapter 21. I am looking forward for your response. Thanks

Great video as usual sir.

Excellent way of presenting the ideas of structures. Thanks Sir.

the PM curve option is not activated, what might be the reason??

Hi sir, if I have inclined rafter fixed to the column, and below of it there is a beam, in actual the beam is rested below the rafter casue of end plate connection between the rafter and column so, shall I move the beam it self to how much it is beneath the rafter? or shall I use the link command to join between the below beam and rafter??

excellent sir

Love you Sir

Nice explanation Sir. I had this idea that when we plot the response spectra of an SDOF subjected to various earthquakes on a single graph, the ordinates of the envelope of all those spectra are called spectral acceleration.

sir can you explain yield line method for slab equivalent frame method ,strut and tie method finite element method ,linear static method ,non linear ststic method

Please make a video about the changes between ASCE 7-16 to 22 for seismic 😊

Thank you, sir, for explaining in a detailed manner. Is it possible in future can we design wind with nonlinearity with some level of dictility ?

Sir. Where i can download acse book

RIP Dabney Coleman

so helpfull! thank you!!

Thanks a lot sir.....lots of love from India.Your information is the most effective to me.

Thank you for clear explanation sir

Just reading out what is in your slides doesnt help, explain!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

You mix your word often which makes no sense, work on forming english sentences

RIP Dabney Coleman

Thank you for this informative video. It's the first time someone's explained in simple language the difference between deterministic and probabilistic assessments of PGA (31:35)

Sir Response spectrum of building code which is plot by a eqation. In this spectrum, what we tell that the spectrum is MCE or DBE Level?

Great way of explaining nonlinear analysis in a most simple and technical manner.

Dear sir we have need of your notes please provide us ur hand written notes

Sir we have need of your handwritten notes

Sir we have need to ur hand written notes how we get ....
