  Abstract


The determination of the fundamental natural period of vibration is essential to design a structure against earthquake loading. Current design codes in India such as IS 1893(Part 1):2002 or IS 875 (Part III):1987 provide formulas for the approximate period of earthquake-resistant building systems, which are dependent only on the height of the structure or number of stories. Such a formulation is overly conservative and unable to account for structures with geometric irregularities. This study investigates the fundamental periods of different types of reinforced concrete earthquake resistant building structures having structurally irregular frames (both vertical and horizontal). A total of 66 MRF structures for set-back, 168 MRF structures for mass irregularity, 90 MRF structures for soft-storey irregularity, 72 MRF structures for re-entrant corner irregularity and 160 MRF structures for torsional irregularity due to heavy mass are analyzed with STAAD.Pro-V8i.
