Seismic evaluation of mutistorey building with soft storeyeSAT Journals
ABSTRACT Most of the reinforced concrete (RC) structures are not designed to resist major or moderate earthquakes. The designs of such building are regularly done by using gravity loading without considering the earthquake load. Thus these buildings are vulnerable during the event of an earthquake.. In present study bare frame and soft storey are modeled considering special and ordinary moment resisting frame (SMRF & OMRF) for medium soil profile under zone III. The masonry infill panels were modeled as equivalent diagonal strut seven and ten storey buildings are considered to represent medium and high rise buildings , equivalent static and response spectrum analysis was performed on bare frame, infill frames as brick and infill frame as solid concrete block using SAP 2000 V15 software. Nonlinear static pushover analysis carried out for default-hinge properties, M, PM, V and P hinges are applied to beam, column and strut available in some programs based on the FEMA-356 and ATC-40 guidelines. While such documents provide the hinge properties for several ranges of detailing, programs may implement averaged values. The performance of building frames were compared with bare frame, in terms of ductility, safety, and stiffness. The investigation concludes that the performance of the buildings having non-ductile moment resisting frames can be improved by adding infill walls and SMRF building models are found more resistant to earthquake loads as compared to the OMRF building models in terms of performance level, performance point and hinging variation the performance of building for OMRF lies in LS to CP range where as SMRF are found under life safety range ,this shows in high seismicity region the ductile detailing must be adopted to avoid the vulnerability of building for tremor loads.

Seismic analysis of base isolated building in rc framed structures 1868Anusha Reddy
An earthquake is the shaking of the surface of the Earth, which may be dangerous enough to destroy major buildings and kill thousands of people. To protect the structures from earthquake effects there is a system known as base isolation systems. Base isolation is the technique is most widely accepted and used for seismic protection of the building in earthquake prone areas. The aim of this research is to study the mode period of different structures under fixed condition and base isolated condition. In this study, two building’s are considered first structure is G+13 storey building and second is G+5 storey building which is designed and analyzed in E TABS 13.2.1 software.
Behavioural Study of RC Flat Plate Multi-Storey Building Persuaded By Stiffne...IJERA Editor
With a very swift development in urban areas the framed structures which are infilled by brick masonry or
concrete blocks are widely used as partition walls and also exterior walls. Masonry infill walls are common
element in structural system which modifies the conduction of building under the lateral load. These structures
resist the moderate earthquakes and accomplish well in such a prime manner that even if they have no load
bearing function. Evidently, during the time of resolution of such a multi-storey structure, the infilled frame is
considered as bare frame, because IS codes do not provide any guide lines for the analysis and design of RC
frames with infill wall. This paper addresses the numerical study of G+10 RC flat plate framed building with
different cases i.e, soft story at ground level (Basement), with soft story at 5th floor level, without soft storey and
bare frame building by using ETABS as soft computing tool. All these cases are analyzed for equivalent static
method and Response spectrum method. By this, dynamic properties are evaluated and according to the results
obtained conclusions are drawn
Study of Strength of RC Shear Wall at Different Location on Multi-Storied Res...IJERA Editor
Shear wall systems are one of the most commonly used lateral load resisting systems in high-rise buildings. Shear walls have very high in plane stiffness and strength, which can be used to simultaneously resist large horizontal loads and support gravity loads, making them quite advantageous in many structural engineering applications. There are lots of literatures available to design and analyze the shear wall. However, the decision about the location of shear wall in multi-storey building is not much discussed in any literatures. In this paper, therefore, main focus is to determine the solution for shear wall location in multi-storey building. A RCC building of six storey placed in HYDERABAD subjected to earthquake loading in zone-II is considered. An earthquake load is calculated by seismic coefficient method using IS 1893 (PART–I):2002. These analyses were performed using ETABS.
Highly Deformable Energy-Dissipating Reinforced Concrete Elements in Seismic ...IJERA Editor
Incorporating scrap tyre rubber particles as partial replacement for aggregates has been found to produce concrete with improved ductility, deformability and damping which are desired characteristics of a viable material for enhancing structural response to earthquake vibrations. An analytical study using Drain-2dX was carried out to investigate the response of 4-storey, 3-bay reinforced concrete frames on innovative rubberised concrete deformable foundation models to simulated earthquake scaled to 5 different peak ground accelerations. Stress-strain properties of 3-layers aramid fibre-reinforced polymer (FRP)-confinement for concrete incorporating waste rubber from scrap vehicle tyres were used to model the elements of this foundation models. With a partial decoupling of the superstructure from the direct earthquake force, the models showed up to 70% reduction in base shear, an improved overall q-factor of 7.1, and an estimated frame acceleration of 0.11g for an earthquake peak ground acceleration of 0.44g. This implies that a non-seismically designed reinforced concrete frame on the proposed rubberised concrete deformable foundation system would provide a simple, affordable and equally efficient alternative to the conventional and usually expensive earthquake resistant concrete frames. A supplementary Arrest System (SAS) was proposed to anchor the frame from the resulting soft storey at the rubberised concrete foundation. A further research is recommended for the design of concrete hinges with rubberised concrete as used in the model with the most impressive response
