Various testing procedures were adopted to find the effectiveness and compatibility of fibre in concrete. In this paper the study was conducted about engineering and mechanical properties of Kevlar Fibre and in comparison with other fibers, testing of Kevlar fibre under various conditions and the very systematic comparative study was been carried out on the properties of Kevlar with respect to other fibers. The main objective of the study is to find out the mechanical properties and compatibility of fibre so that it can be used in concrete to enhance its properties and to increase its durability.

Base isolation is one of the most widely accepted seismic protection systems used in structures in earthquake prone areas. The base isolation system separates the structure from its foundation and primarily moves it relative to that of the upper structure. The aim of this study is to reduce the base shear and story drifts due to earthquake ground excitation, applied to the superstructure of the building by installing base isolation devices at the foundation level and then to compare the different performances between the fixed base condition and base-isolated condition. In this study, the (G+9) unsymmetrical steel. Structure is used as test model. Friction base isolator is used as isolation system in this study. Nonlinear time history analysis is used on both of fixed base and base isolated structure. The comparative study of the acceleration, displacement and base shear was carried out for both fixed base and base isolated structure. It is found that the displacement is increased with period of the structure in case of base isolated structure and the acceleration is reduced and vice versa.

Bracing element in structural system plays vital role in structural behavior during earthquake. The pattern of the bracing can extensively modify the global seismic behavior of the framed steel building. In this paper the Response Spectrum Analysis is carried out on (G+10) rise steel building with X bracing system.Natural frequencies, fundamental,time period, mode shapes and peak storey shear are calculated.The resistance to the lateral loads from wind or from an earthquake is the reason for the evolution of various structural systems. Bracing system is one such structural system which forms an integral part of the frame. Such a structure has to be analysed before arriving at the best type or effective arrangement of bracing. This paper discusses about the efficiency and the effectiveness the use of bracings and with different steel profiles for bracing members for multi-storey steel frames. In this study, an attempt has been made to study the effects of bracing systems and their placement so that to reduce the lateral displacement of the structure.

The study involves the design of the R.C frame or the combination of various structural stiffness elements that will be more economical in terms of cost and more efficient when subjected to seismic forces so that loss of property and loss of lives is reduced to the minimum during natural catastrophes. The study is based on the comparative studies of the frame of same plan but of different stiffness configuration. The various parameters that were studied were time period, frequency, displacement and peak storey shear.the results that were obtained indicated that the framed structure with brick infill masonry performed very well under seismic forces and the structural displacement was also reduced the only failure that was observed during the application of lateral force the stress concentration is generated at the beam column joint which leads to the failure of the structure or may generate plastic hinge at beam column joint. The combination of shear wall with brick infill and proper anchorage at the joints which may prevent the failure of structural elements and the structural may act as single unit under dynamic loading.

The existing FEMA-356, ATC-1997a and the result from the previous research reports which were used in the analysis of the structure. This paper also aims at establishing comprehensive seismic design as well as characterizing earthquake response characteristics and failure mechanisms of structures through analytical investigations under large earthquake. To ensure the safety of the structure only shear wall technique has been widely used and not much has been done with respect of core structures. In this paper instead of shear wall, Concrete Core has been used; the displacement was calculated by default procedure and the yield of the structure in both the direction result in the development of plastic hinge under push over loads. The outcomes would lead to develop the most efficient and most economical frame which can withstand the major earthquake. It also lead to motivate advances in seismic design practice. The core provided within the structure resulted in the less lateral displacement and restricted the development of the plastic hinges at the initial stages hence making the design robust and acts as an energy dissipater.
