New Lateral Force Distribution for Seismic Design of Structures Based on Seismic Demand Ratio

The design of earthquake-resistant buildings starts with defining the maximum lateral earthquake forces or their resultant. The amount of these forces depends on various factors, including coefficient of system behavior which depends on overstrength and its ductility. In this study, a method is presented for designing an earthquake-resistant system in which the distribution of lateral forces is...

Robust control of hysteretic base-isolated structures under seismic disturbances

The main objective of applying robust active control to base-isolated structures is to protect them in the event of an earthquake. Taking advantage of discontinuous control theory, a static discontinuous active control is developed using as a feedback only the measure of the velocity at the base. Moreover, due to that in many engineering applications, accelerometers are the only devices that pr...

Seismic Response Reduction of Structures using Smart Base Isolation System

In this study, control performance of a smart base isolation system consisting of a friction pendulum system (FPS) and a magnetorheological (MR) damper has been investigated. A fuzzy logic controller (FLC) is used to modulate the MR damper so as to minimize structural acceleration while maintaining acceptable base displacement levels. To this end, a multi-objective optimization scheme is used t...

Analytical study of seismic durability and its destructive effects on structures and distribution of accelerated seismic durability of Iran

Background and objective: Experience with past earthquakes and numerical analysis confirms that the durability of strong earth motion, significantly can affect the amount of failure of civil engineering systems. However, if the durability is related to a parameter which describes the intensity of the earth's motion, such as maximum velocity or maximum acceleration or spectral acceleration, then...

Earthquake Analysis of Base Isolated Structures Including Soil-Structure Interaction

A frequency domain dynamic analysis is needed to obtain the response of structures constructed on a system of base isolators on flexible soil when subjected to earthquake ground motion. In such systems, the lateral stiffness of the base isolators is so small, compared to the structural stiffness, that in an earthquake attack the fundamental vibration mode dominates the response. With this in mi...
