A Conceptual Design Approach of Coupled Shear Walls

Earthquake causes considerable damage to a large number of RCC high-rise buildings and tremendous loss of life. Therefore, designers and structural engineers should ensure to offer adequate earthquake resistant provisions with regard to planning, design, and detailing in high-rise buildings to withstand the effect of an earthquake and minimize disaster. As an earthquake resistant system, the use of coupled shear walls is one of the potential options in comparison with moment resistant frame (MRF) and shear wall frame combination systems in RCC high-rise buildings. Furthermore, it is reasonably well established that it is uneconomical to design a structure considering its linear behavior during earthquake. Hence, an alternative design philosophy needs to be evolved in the Indian context to consider the postyield behavior wherein the damage state is evaluated through deformation considerations. In the present context, therefore, performance-based seismic design (PBSD) has been considered to offer significantly improved solutions as compared to the conventional design based on linear response spectrum analysis.

Microbial Electrochemical Technology

Abstract Transition from fossil-based to bio-based economy is a global need for the production of renewable forms of energy and products. Microbial electrochemical technologies (METs) are majorly catalyzed by the conventional electrochemical processes through microbial catalysis. This chapter summarizes the origin and history, diversification, and application of MET as a sustainable platform technology in the domain of waste remediation, resource recovery, and bioenergy generation.

Investigation into the Behavior of Coupled Shear Walls

An effective design technique for symmetrical coupled shear walls is presented in this paper. The proposed formulation, including assumptions and steps with mathematical formulation, has been elaborated to arrive at the design technique. An example has been considered to validate the technique with the DRAIN-3DX and SAP non-linear analysis. A parametric study has also been considered to find out the limitations of this technique and suggest remedial action. It is concluded that the proposed design technique can be considered in the design of coupled shear walls under seismic motion.
