Abstract:
There are a number of methods and standards to compute the nonlinear static response of the frame, among them finite element softwares and building codes are most known methods. However there is a limited number of studies that compares the results from finite element softwares and building codes. The objectives of this study incudes (i) to compare the number, location and level of occupancy of plastic hinges and force vs displacement relationship between SAP 2000 and ABAQUS using six different frames, (ii) to evaluate the effect of shear stirrups spacing on force vs displacement in SAP 2000 and ABAQUS for one bay one story frame (iii) to compare design moment between codes (ACI 318 and ES EN: 2015) and finite element softwares in sway and nonsway cases. From the analysis results found, there were a difference between ABAQUS and SAP 2000 in the number of plastic hinge, location and level occupancy. However, in force vs displacement relationship, the base shear capacity in ABAQUS is higher than in SAP 2000. The effect of shear stirrups spacing on the force vs displacement result shows that, the stirrups spacing has a role only for the enhancement of displacement capacity in SAP 2000. However, in ABAQUS the stirrups spacing has a role on enhancement both base shear and displacement. The design moment calculated by SAP 2000 for non-sway slender column was much lower than all the analysis result computed. Regarding to sway columns, the design moment calculated by finite element software’s were lower than codes. From the results it is recommend that, for earth quake prone area sufficient amount of lateral reinforcement should be given to increase the ductility structure. In SAP 2000 to capture the slenderness effect, in the middle of the member, additional node should be presented.
