strains as a performance indicator
Posted: 15 Apr 2016, 13:14
Dear all;
I'm investigating the response of multi-degree of freedom building under artificial ground motion records through the nonlinear dynamic analysis of inelastic beam-column fiber element model. in past couple years i used to do some stuff in seismostruct v5 where the section materials are : unconfined, confined concrete and steel but we couldn't able to track the performance through the materials strains/capacity. in the most recent seismostruct software (i.e. v7.06) which i used these days i saw that it becomes two types of materials by which the confinement is calculated in other integrated section in the same dialog.
my question is: when i track the performance through materials strains i saw that the program tells that some elements reached the bar fracture (for example) in an elements, so i can tell that i is the longitudinal bar of that elements
but when the strain of concrete elements reached 0,01 i couldn't understand is that for the core materials ( the confinement part of that section) or not. maybe another question is of significant that i need to modified the stirrups materials strength in this way by modifying every single elements which seems to me very challenging.
