Re: Incremental dynamic analysis vs pushover

actually the problem is a little be different. I don't have problem with dynamic analysis but with the comparison with pushover!

Incremental dynamic analysis vs pushover

<r>Dear seismo,<br/>
I was working with a big brigde in cls and doing incremental dynamic analysis I had big differences with the pushovers results.<br/>
So I tried to do the same type of analysis but on a single pier of the bridge.I did pushover in X direction and after With the same accelerogram ...

Re: strange hysteretic curves

<t>I've another problem. I did pushover analysis in the X direction and dynamic analysis. Increasing the accelerogram to searching IDAs curve what I noted is that the curve doesn't follow the pushover one but it is more or less elastic also for base shear really higher than the capability given by ...

strange hysteretic curves

<r>Dear seismo,<br/>
trying to do a dynamic analysis on a multispan srch brigdes in reinforced concrete I noted some strange behaviour in the hysteretic curves.<br/>
I used an accelerogram defined with 0.01 sec time history and i used steps of 0.005 for the analysis. The accelerogram is defined for ...

push-over doubts

<t>Dear Seismo,<br/>
I need to do a pushover analysis of a R.C. arch bridge. My question is, to do a pushover analysis with horizontal load proporzional to masses, there is not a way to do it without putting incremental loads? Because I need that the loads automatically are disposed proporzional to ...

Re: Post-Peak behaviour

<t>Dear Huffte,<br/>
thanks a lot for your help.<br/>
I think it coul be a problem of my processor power because I tried a lot of attempts but it seems to give me always not good results.<br/>
Anyway, which steps you mean to change? The steps of the load curve or directly in the time history stages ...

Re: Post-Peak behaviour

Thanks Huffle for your suggestion. anyway, I did yet a model also with less element like 8 or 16 per arch but the problem is the same.

Post-Peak behaviour

<r>Hello Seismo,<br/>
I'm trying to modelling a little small arch bridge with different kind of materials, reinforced concrete and masonry too, modifynig the constitutive law of concrete material of default. I'm working with static time-history analisys, but what happens in each model is that it ...
