| Summary: | Seismic performance of a structural system in earthquake-resistant high-rise
buildings in terms of strength, stiffness, ductility and energy dissipation. Special
Moment Frames (SMF) are known to have high ductility with relatively low stiffness
and strength, while Steel Plate Shear Wall-SPSW systems have high stiffness,
strength and ductility. This research is a numerical study to study the contribution
of the addition of SMF to the improvement of the seismic performance of the SPSW.
Parametric studies were carried out on three types of structures: SMF, SPSW and
SPSW-SMF combination, taking into account the parameters of SPSW plate
thickness, SPSW size aspect ratio, number of SPSW bays. In a parametric study
involving a large number of parameters, the same beam-column size was used for
SMF to study the contribution of the additional structure in the form of special
moment frames (SMF) to the performance of the SPSW-SMF combination structure.
Non-linear analysis in the form of pushover static analysis (NSP) and time history
earthquake dynamic analysis (NLTHA) was carried out to determine the behavior
of the structure and to compare the performance of the three types of structures in
carrying seismic loads.
The results of this study indicate that variations in the thickness of the steel plate
do not have a significant effect on the overall structure performance. The effect of
increasing the aspect ratio of the steel plate gives a slight increase in the
performance of the structure, but the effect of increasing the number of spans of the
main system provides a significant performance. SPSW FRAME and SMF-SPSW
combination show higher performance than SMF, however in general it is shown
that the contribution of SMF seismic performance is not very significant in the
SPSW-SMF combination. |
