Structural damage is more accurately quantified by the damage indices than by a single engineering parameter.
Damage Indices for Structures Using probabilistic nature, structural seismic damage of RC structures is more accurately quantified by the damage indices than by a single engineering parameter, such as interstory drifts.
For an analytic model, the earthquake engineering simulation software, Ruaumoko 2D [4] is used. 40 recorded ground motion records used for ATC63 Project [5] is utilized for performing nonlinear time history analyses.

MECHANICAL & THERMAL PROPERTIES OF SISAL EPOXY/ BANANA EPOXY COMPOSITES- A REVIEW J.M.PRABHUDASS1, a * and K.PALANIKUMAR1, b 1 Research Scholar, Faculty of Mechanical Engineering, Department of Mechanical Engineering, Sathyabama University, Chennai 1 Department of Mechanical Engineering, Sri Sai Ram Institute of Technology, Chennai, Tamil Nadu, India aprabhu.mech@sairamit.edu.in , bpalanikumar@sairamit.edu.in Keywords: Natural fibers, Composites, Sisal, Banana, Properties Abstract Composite materials are preferred in all engineering applications, currently, as their properties are superior over the traditional materials.
Introduction Composite materials do emerge as the promising source to quench the thirst of the current engineering world in various applications.
This advantages finds place for the composites in important applications like Automobiles, Aerospace, civil construction works, etc. [6] Composites, defined by Jaritz, are the multifunctional material systems which possess characteristics which cannot be obtained from any discrete material. [3]Composites, generally, are made by combining two or more compatible materials physically, which are different in composition and characteristics.
