INTRODUCTION If in an earthquake, the structure oscillates like a swing and attains its original position as soon as earthquake stops. Seismic isolation is basically decoupling of the superstructure from the substructure by … Base isolator is a device which decouples a super structure from its substructure resting on a shaking ground thus protecting structural and non-structural components. This project deals with design, modeling and analysis of G+6 rigid jointed plane symmetrical RCC frames for two cases.

The main aim of the base isolation technology is high-rise and super high-rise buildings, the greater the is used to design the building structure but it cannot be used to advance analysis in … The developed procedure improves the conventional RSM in two aspects: (1) the seismic response of the base-isolated building is computed by applying the modal analysis to the superstructure only, which is typically considered as a classically damped system, rather than to the overall structure having nonclassical damping; (2) the BIS can

    Where possible, recommended code provisions and design rules are given. The characteristics of the mechanical energy dissipating devices developed to date are discussed and material specification provisions presented. The requirements for construction of base isolated structures and for maintenance of the devices are given. Comparative Seismic Analysis of Base Isolated and Fixed Based RC isolator in building at base level significantly increases the time period of the structure, which means it reduces the structural design of buildings and bridges in high risk areas.

    Omar and Arturo,(2000) presented a methodology for the design of base isolated structures located in the Mexican Pacific Coast using dynamic principles. The displacement design spectra (DDS) were defined for different damping ratios (Оѕ = 0.05, 0.10, 0.15, and 0.20) to consider that there are both low damping and high damping base isolators. 12/12/2015В В· Sand is found to be effective only at very high amplitude (> 0.65 g) of motions. The performance of a composite consisting of sand and 50% shredded rubber tire placed under the footing is found to be most promising as a low-cost effective base isolator.

    Seismic Analysis of Fixed Based and Base Isolated Building Structures High-rise buildings or buildings rested on soft soil are not suitable for base isolation. To design and study the effectiveness of lead rubber bearing used as base isolation system. 3) To carry out comparison between fixed base and Based on China building seismic code (GB5011-2010), an overview about base-isolated designing method is presented in this paper. The composition of base-isolated structure, design process, design content, application in practical engineering are involved .The purpose of this paper is to make structural engineers have an overall understand about base-isolated structure design, and promote the

Presently technique which are used for high-rise buildings are very costly. Materials used in base isolation are lead rubber bearing, laminated rubber bearing etc, are very costly and it is very complex to execute. Due to the high cost this type of base isolation material can’t be …

    3/20/2016 · Foundation Design. Foundation is the base of any structure. Without a solid foundation, the structure would not hold for long. We have to be very cautious with the design of foundations because our entire structure rests on the foundation. The job of a foundation is to transfer the loads of the building safely to the ground. In this paper, a closed loop control approach for controlling the vibration of buildings under earthquake excitations is introduced. An active hybrid control combining base isolation and active tuned mass damper (AMD) installed on the lowest floor of a base-isolated frame building is investigated. The Active control force is controlled by the mean of a proportional–integral–derivative (PID
