Dear Dr.Silvia I want to do force control pushover analysis but it can't give me negative branch of base shear vs. drift curve. i use a for loop and in each step increment a little my force with inverse TRIANGLE distrubution. please guid me. if something like your examples in manual for pushover wit...

hi,
i have a quastion, if i define a mass dencity for a beam with hinges, it will be nececcery that define nodal mass again for transiant analysis and eleload for gravity analysis.(with attention to mass and weight of that beam with hinges).

hi,
i really need answer to my question, please reply me

hi, I have 4 question: 1) i want to know what diffrence exsit between [QzSimple1 and QzSimple2], [TzSimple1 and TzSimple2] and [PySimple1 and PySimple2]. 2) if i use beam with hinges for both beam and column in concrete frame,it will be good i use distrbuted load with eleload command or concetrated ...

hi dr.silvia,
how i can run my tcl.script in Crimson Editor ?
i want when i click on a botton my tcl script run in opensees, like TclEditor

hi, I want to use ShallowFoundationGen for simulating BNWF that a concrete frame with multi bays and story stand on it.For example, in a frame with 3 bays, 4 column stands on a footing ,if my foundation is a strip, what node can be $ConnectNode? $ConnectNode is came in command "ShallowFoundatio...

hi dr. silvia, I want to use beam with hinges in my concrete frame. and in joint of beam and column use rigid zone with geomTransf command.I want to know when i enter length of plastic hinge, i must add rigid zone length to length of plastic hinge that is got from experimental formula (Lp=0.08*L+0.0...

hi, more explenation about matrial (e.g. concrete01 02 03 04 and steel01 02 reinforcing steel ) and application of them in different problom and diffrence of them. more explenation about fiber section and mesh sizing of fiber and about nonlinear beam column and number point of intgration because it ...

hi silvia,
can i ask what is your verification cases of opensees about pushover analysis for RC frame ?
can you say how i can access to it ?
have good holyday

hi silvia, can you say what difference between dispbeamcolumn and nonlinearbeamcolumn is exist? i build a model one time with dispbeamcolumn and second time with nonlinearbeamcolumn. and pushover curve of disp.. is above a nonlinear.. ,how can i get same result form both of them? if any refrence abo...

hi silva,
is any commad in opensees for modeling rigid zone in intersction of beam with column ? a rigon with a half dimontion of beam or column
if i wanted model it what i can do
thanks a lot

hi silvia, i modeled a two story 4 bay concrete fram, with opensees and idarc and done pushove analysis. but result hasn't good agreement with each other in yield branches. i want to know where is the problom? falling branch of pushover curve wih opensees started when in idarc this part goes up slow...

hi silvia,
this link doesn't work, when i click on it can't display any thing.

hi silvia, thanks for your reply. i install building tcl viewer but when i load a tcl script -one of your example in manual- it doesn't show any result. is wrong with my instalation? or it only load tcl script with spacial configuration. before i accedent with this problem with osp. please guid me. ...

hi, i use fiber section in my work, changing the number of fiber in cocncrete patch affected the pushover analysis, when i use a mesh with 2 cm my analysis done but when i change it to 3 cm , my result faild. i want to know is there any suggestion about number of dividing patch of concrete in buildr...
