Unified Reliability and Design Optimization in Earthquake Engineering
In this paper, a methodology is put forward that takes advantage of the emerging focus on structural damage in earthquake engineering. Contrary to the traditional focus on collapse limit-states in reliability analysis, a versatile “unified” limit-state formulation is employed. The methodology underscores the advantages of formulating explicit probabilistic models for the ground motion, structur...
متن کاملControl of Structural Response Under Earthquake Excitation
This study firstly proposes some representative simple methods to obtain the suboptimal passive damping and stiffness parameters from the optimal control gain matrix since it is not possible to add the exact optimal damping and stiffness parameters to the structure in practice. It is shown numerically that modifying the structural damping and the stiffness in the proposed suboptimal ways may su...
متن کاملEvaluating the Resiliency of Baghershahr against Earthquake
BACKGROUND: Because of the vulnerability of human settlements to natural disasters and damage caused by them, the study of the resilience of settlements has become critical in planning urban areas. The purpose of this paper is to evaluate resiliency of Baghershahr, a town with a population of 65000, locates in 4 km from Tehran city, against earthquake. METHODS: The research data were collected...
متن کاملApplication to Adaptive Control to Synchronous Machine Excitation
Self-tuning adaptive control technique has the advantage of being able to track the system operating conditions so that satisfactory control action can always be produced. Self-tuning algorithms can be implemented easily. Because the power systems are usually time varying non-linear systems and their parameters vary, adaptive controllers are very suitable for power systems. Characteristics of a...
متن کاملEffect of the frequency content of earthquake excitation on damage detection in steel frames
In this study, the effect of earthquake frequency content and noise effects on damage detection has been investigated. For this purpose, the damage was defined as nonlinear behavior of beams and columns, and several ground motion records were scaled so that some elements yield under the applied excitation. Then the acceleration response data of each floor obtained using the nonlinear dynamic an...
