hello everybody, In the drucker prager material of opensees there is a constant To used for softening parameter delta2 is the value of constant correct that value should not be maximum tensile strength of the material where it becomes plastic please explain be the softening parameters in drucker pra...

dear all please someone can explain me softening parameter in drucker prager material i have tried different values of delta 2 but there is no change in stress - strain curve i am posting my script please give me suggestions After maximum tensile stress the stress strain curve remains constant and t...

hello everyone can anyone please explain me the tension softening parameter in drucker prager material what should be it's value in case of masonry structure having tensile stress of 4.6N/mm2 i have got literature in which it is mention in terms of fracture energy can anybody help me in relating thi...

dear fmk as u said i model a 3d pier and i am getting only periods but no mode shapes i am posting my script can you please check # Units: N, m, sec # ---------------------------- # Start of model generation # ---------------------------- # Create ModelBuilder with 3 dimensions and 3 DOF/node model ...

what if i want to have mode shapes of a solid bridge pier i have to model it as 2D with lumped masses and then find its mode shapes? or there is any other way in opensees through which i can get mode shapes of solid 3D bridge pier

perfect thankyou very much

hey everybody, here i have modelled a cantilever beam using 3d elements as per opensees example 8 but still it says it is failing kindly check my code and let me know my mistake please # ---------------------------- # Start of model generation # ---------------------------- # Create ModelBuilder wit...

hey kgkoktsi

so finally is your problem solved,i am also trying to work on similar type of model, if possible can you please post the script of your program it will be very helpful since i am new to open sees

did u find any answer? if yes please give me i m trying same

Hey can i use Open Sees for modelling a Solid Continuum in my case a Masonry pier for non-linear dynamic analysis,if yes can any one please post some programmed examples it will be really helpful to me
