This document analyzes the seismic performance of an 11-story conventional reinforced concrete (RC) framed structure compared to a flat slab structure. Both linear and nonlinear analysis methods are used to evaluate the structures' performance under seismic loads. The natural period, base shear, story stiffness, and story displacement are calculated and compared for RC and flat slab models with and without shear walls. The results show that the flat slab structure generally has a higher natural period, base shear, and story displacement but lower story stiffness compared to the RC structure. Shear walls are found to significantly increase the stiffness and seismic performance of both structural types.

Seismic Analysis of G 10 Storey Building with Various Locations of Shear Wall...ijtsrd
Shear walls are specially designed structural members provided in the multi storey buildings to resist lateral forces. These walls have very high in plane strength and stiffness, which can resist large horizontal forces and can support gravity loads. There are lots of literatures available to design and analyse the shear wall.

Dynamic Analysis of RC Multi-storeyed Building - A Comparative Studyijsrd.com
In India with a seismic moderate zone, the equivalent static force method to estimate the seismic force, subsequent vulnerability and behavior of RC building under seismic load is inadequate. The main goal of this paper is to show how the modal analysis can contribute to the understanding the behavior of building using Response Spectrum Method. In this study, Dynamic Analysis of four storied Reinforced Concrete building was investigated using Staad pro and Etabs software packages. For this, Response Spectrum Method was used to evaluate the base shear, frequency, modal mass participation and the mode shapes of the building have been plotted for 15 frequencies. Seismic Zone 3 has been considered and base shear was calculated as per the procedure recommended by IS 1893-2002. The results shows that only slight variation in frequencies and modal participation factors was observed as each software has its own way of considering the mass.
Performance based analysis of rc building consisting shear wall and varying i...Yousuf Dinar
Abstract:
Metropolitan cities are under severe threat because of inappropriate design and construction of structures. Faulty building designed without considering seismic consideration could be vulnerable to damage even under low levels of ground shaking from distant earthquake. So, structural engineers often are more concerned about the constructing Shear wall without knowing its performance with respect to infill percentage which may lead it to an over design state without knowing the demand. Nonlinear inelastic pushover analysis provides a better view about the behavior of the structures during seismic events. This study investigates as well as compares the performances of bare, different infill percentage level and two types of Shear wall consisting building structures and suggests from which level of performance shear wall should be preferred over the infill structure. To perform the finite element simulation ETABS 9.7.2 is used to get the output using pushover analysis. For different loading conditions, the performances of structures are evaluated with the help of base shear, deflection, storey drift, storey drift ratio and stages of number of hinges form and represented with discussion.
DESIGN AND ANALYSIS OF MULTI STORIED STRUCTURES USING STATIC NON LINEAR ANALYSISIjripublishers Ijri
In plan during the seismic excitation using nonlinear static analysis (pushover) have been performed on the
same structure. The literature pertaining to pushover analysis is reviewed. The pushover analysis adopted
in the present study is on similar lines with the procedure presented by Ashraf Habibullah and Stephen
Pyle using ETABS V 9.7 structural analysis software. The effect of earthquake force in a idealized G+4 story
building under maximum earthquake zone, with the help of pushover analysis has been investigated and
the results were compared in terms of base shear, displacement, spectral acceleration, spectral displacement
and effective damping and effective time period .to strengthen the symmetric and un symmetric RCC
framed buildings` steel braces are included by using retrofitting method.
This research introduces a new simple, efficient, and practical procedure to design
the reinforced concrete (RC) circular slabs which have large diameters. The principal
idea of this paper concerns to use the isotropic perpendicular RC straight joists to
resist the external load. The yield-line theory was adapted to analysis the circular
waffle slabs. The steps of design were according to the ACI Code provisions. Fixed
and simply supported circular slabs were presented. Closed form equations have been
driven by author for the purposes of analysis and design this type of slabs by the
present procedure. Uniformly distributed load was considered, that represent almost
practical cases. Useful illustration example is presented in this study according to the
available materials in Iraq to facilitate the job of designers. The good performance of
RC circular slab which design by the present procedure proved clearly the efficiency
of this technique.
