Probabilistic assessment of asymmetric plan steel-concrete composite shear wall-RC framed building - Vol. 48, Issue 04 - Chennai CSIR- Strctural Engineering research Centre 2021 - 284-306p.
Fragility curve is a powerful tool in performance-based analysis to
assess the seismic risk of the structural system. Many parameters like
transitional damage states, plan asymmetry and different measures of
seismic intensity and damage measures influence the fragility curves.
It is essential to establish fragility diagrams for shear wall system
where torsion is exhibited. In the present paper, the fragility diagrams
of torsion imbalanced steel-concrete composite shear walls (CMSWs)
building is developed. In current work, trapezoidal plan building frame-
CMSWs structure is simulated to one fourth extents to substantiate
analytical findings of modal and corner point’s characteristics with
AZALEE shake table results of SMART 2008 project. Incremental
Dynamic Analysis is conducted using a suite of fourteen real bi-
directional orthogonal horizontal ground motion records. Further,
fragility curves of composite shear wall building are compared using
pre-defined damage thresholds of SMART 2008 project and HAZUS
2003 technical manual. Damage states of SMART 2008 have been
derived for torsion induced Nuclear Power Plant building situated in
France. While HAZUS defined limit states for common reinforced
concrete buildings with shear walls situated in the United States. The
damage states for asymmetric plan building with CMSWs are not
prescribed by any seismic code. Hence, damage indices are
established in the context of naturally generated incremental dynamic
curves for the structural model to obtain more realistic results.
