Abstract

DUCTILITY, or deformation energy, is by far the largest source of ENERGY DISSIPATION of structures, since normal levels of internal damping represent only a small portion of ENERGY DISSIPATION. However, large material deformations such as that required in building components to perform in a ductile manner, are often associated with cracking and degradation of its strength, particularly in concrete structures. Added Damping and Stiffness (ADAS) elements are mechanical devices that design to be installed in either new or existing buildings. ADAS elements, if properly designed and installed, can increase the strength, stiffness and usable ENERGY DISSIPATION capacity of a moment resistant frame (MRF), in addition the ENERGY DISSIPATION is concentrated to locations, which have been specifically designed for this purpose. This paper proposes a new alternative design approach for buildings with the application of ADAS elements and determining of DUCTILITY and RESPONSE MODIFICATION FACTOR of structures by the use of NONLINEAR STATIC ANALYSIS and capacity spectrum method (CSM). Also DUCTILITY and RESPONSE MODIFICATION FACTOR of ordinary moment resistant frames with and or without ADAS elements have been compared. The results of these investigations indicated that equal viscose damping of moment resistant frames with ADAS elements is more than moment resistant frames. Therefore base shear forces of these structures are less than MRF and the weight of steel used and foundation construction costs of these structures are less.
