“…The importance of a behavioural method was emphasized by [15], who used the aggregated particular flexible springtime and the beam based on the Behavioural Winkler Basis (BNWF) framework to derive vulnerability curves for a collection of concrete that has been strengthened event resistive structures. Another example of the effect of (nonlinear) Soil-Structure Collaboration on the seismic susceptibility of frame structures made of reinforced concrete was offered by [16] utilizing the beam approach on the Dynamic Winkler Basis framework. Although these models can be very comprehensive, they could exaggerate shear-induced deflections in the soil underneath foundations with shallow depths and they are limited to capturing the displacements as an outcome of the combined impact of compressive strains.…”

In the present study, the effect of irregularity of structures of the concrete with special shear walls has been analyzed and modeled by considering the effect of soil-structure interaction by dynamic analysis method with ABAQUS software. The results are presented in the form of diagrams with different soil interaction conditions, the effect of the number of layers was investigated for different soils. The results showed that the bearing system of the flexural frame and the concrete shear wall under the lateral load of the earthquake have good strength and ductility, which makes this issue. This structural system should be used for cities with very high earthquake risk. As the number of floors increases, the effect of the shear walls on increasing the bearing capacity decreases. As the number of floors increases, the final displacement of the frame increases. The results showed that for soil type 1(hard soil which Vs=1000 m/s, v=0.15, q=50000 Kg/m2, P=2000 Kg/m3, r=0.5 m) structural system of concrete shear walls with better displacement, maximum structural stiffness, better behavior was observed in the structure. Three-story frame with concrete shear wall has a significant increase compared to similar frames with more floors, which shows the good performance of this system in structures with fewer floors.

“…The strengthening approach of giving extra columns and lateral buttresses on OFS was seen successful to improve the lateral strength and ductileness. Saravanan et al [12] estimated the susceptibility of OGS by determining the displacement demand magnifier, which assess the extra displacement of an OGS storey as the proportion of the displacement of a proportional ground storey on a frame with uniformly dispersed stiffness.…”

The rising population density, particularly in the urban areas, increased the necessity to accommodate more people within the limited space constraints. The lack of ample space for horizontal expansion has triggered the requirement of tall structures. The increasing usage of superior strength and lightweight materials for the construction of high-rise structures renders it further flexible and lightly damped, thus rendering them extra sensitive towards dynamic excitations. Open Ground Storey (OGS) buildings are buildings where ground storey is kept open mainly for the purpose of parking vehicles. OGS buildings are featured by an abrupt decline in stiffness and strength in the ground storey, and are identified to have been repetitively exhibiting inferior performance during previous earthquakes all around the globe. The present paper focus on finding the seismic responses of a (G+35) structure with OGS with the nonlinear dynamic analysis and vibration control on the OGS structure using a tuned mass damper (TMD). TMDs with mass ratios of 1% to 10% in increments of 1% are considered in the study. The seismic performance of a regular (G+35) structure without open ground storey is also considered for comparison. The seismic responses of the building with OGS are found to be more than that of a regular building without OGS. TMD has been found to reduce the seismic responses of the OGS structure considered in this study. Also, TMD with higher mass ratio is found to offer better control effectiveness.
