[ 1 ] - A New Two-Stage Method for Damage Identification in Linear-Shaped Structures Via Grey System Theory and Optimization Algorithm
The main objective of this paper is concentrated on presenting a new two-stage method for damage localization and quantification in the linear-shaped structures. A linear-shaped structure is defined as a structure in which all elements are arranged only on a straight line. At the first stage, by employing Grey System Theory (GST) and diagonal members of the Generalized Flexibility Matrix (GFM),...
[ 2 ] - A two-step method for damage identification and quantification in large trusses via wavelet transform and optimization algorithm
In the present study, a two-step approach for damage prognosis in long trusses is suggested in which the first step deals with locating probable damages by wavelet transform (WT) and static deflection derived from modal data with the intention of declining the subsequent inverse problem variables. Then, in the second step, optimization based model updating method using Artificial Bee Colony (AB...
[ 3 ] - پهنه‌بندی آسیب‌پذیری لرزه‌ای مناطق شهری با در نظر داشتن تأثیر وضعیت کالبدی به کمک تئوری منطق فازی: مطالعه‌ی موردی منطقه‌ی 7 تهران
یکی از مهم‌ترین گام‌ها در طرح برنامه‌های بهسازی لرزه‌ای برای مناطق شهری در کلان‌شهرها، تعیین سطح خطرپذیری منطقه می‌باشد. شکی نیست که پیاده‌سازی هدفمند یک برنامه‌ی مدون بهسازی لرزه‌ای می‌تواند مناطق شهری را در برابر آسیب‌های ناشی از رخ‌داد زلزله ایمن کند، اما هزینه‌های اجرایی زیاد و زمان‌بر بودن این طرح‌ها، از جمله اساسی‌ترین مشکلات آن‌ها می باشد. بنابراین، بدیهی است یک برنامه‌ی منسجم بهسازی لرز...
[ 4 ] - An effective approach for damage identification in beam-like structures based on modal flexibility curvature and particle swarm optimization
In this paper, a computationally simple approach for damage localization and quantification in beam-like structures is proposed. This method is based on using modal flexibility curvature (MFC) and particle swarm optimization (PSO) algorithm. Analytical studies in the literature have shown that changes in the modal flexibility curvature can be considered as a sensitive and suitable criterion for...
