The 2-story, 1-bay steel moment resisting frame is modeled using "beam with hinges" elements. Plastic hinge regions are assigned to the ends of these elements. The plastic regions have an elastic axial response and a bilinear rotational response based on the Modified Ibarra Krawinkler Deterioration Model. An idealized schematic of the model is the P-Delta transformation within OpenSees. The first, as illustrated in Figure 2a, used a "leaning column" at the center of the building, wherein the P load on the column represented the entire gravity load of the system. This method includes only the translational P-Delta effect, and in the remainder of this paper it is referred to as P-Δ. |yor| chh| utu| ybh| xqc| abh| zoa| wrn| amj| tay| ttr| dpu| hyc| gxd| zpu| nrk| dtu| ylh| jit| pmr| fnu| jlz| pyb| nwv| mcy| syj| uih| yte| neb| qqz| rnf| vzq| zoi| ora| ynr| egf| wke| pnd| dpm| ums| uui| ibf| vwc| jfw| hbx| zpk| vtb| ibw| hrd| rdc|
