Comparison of Alternative Methods for Incremental Dynamic Analysis


Comparison of Alternative Methods for Incremental Dynamic Analysis مقاله با عنوان: Comparison of Alternative Methods for Incremental Dynamic Analysis

محل انتشار: هشتمین کنگره ملی مهندسی عمران - دانشگاه صنعتی نوشیروانی بابل - 17 و 18 اردیبهشت 93
محور: دینامیک سازه
فرمت فایل: PDF و شامل 8 صفحه به انگلیسی می باشد.

چکیده:
The conventional Incremental Dynamic Analysis (IDA) -a parametric method- is a collection of time history analyses under ground motion records which is scaled to different intensity levels. This range is selected so that can cover all structural behavior. Finally, the results are illustrated in one or more diagrams known as IDA curves. Based on recent studies, a few alternative methods to gain the IDA curves have been proposed. In this essay, the proposed methods are discussed and compared. Then the comparison and advantageous of different methods are discussed for a moment-resisting frame (MRF) under a certain earthquake record.

چکیده:
Incremental Dynamic Analysis (IDA) is a parametric analysis method that has recently emerged in several different forms to estimate more thoroughly structural performance under seismic load. It involves subjecting a structural model to one or more ground motion records. This method considers both inherent randomness and model uncertainty, so it used to probabilistic analysis of structures at high seismic loading. The objective of this study is to improve efficient, but accurate procedures for probabilistic analysis of nonlinear seismic behavior of structure. According to the three-parameter Log-normal distribution more rationally describe maximum story drift ratio at a higher value of spectral acceleration. The traditional method based on two-parameter Log-normal distribution is compared with the presented procedure based on three-parameter Log-normal distribution on analytical data. Improvement in the probabilistic estimation of maximum story drift ratio demand are illustrate with a SAC-9 story, moment resisting frame building exposed to a set of 20 ground motion.

چکیده:
Blast-resistant composites and structures are gaining more and more academic and industrial interests currently. The metal sandwich structure is proven to perform better than the monolithic plate with the same mass under blast loading. Besides, the foam or foam-like cores with stacking of graded layers can further mitigate the blast effects. In this work, the dynamic responses of corrugated sandwich plates with various homogeneous and graded core arrangements under shock tube loading are investigated by finite element method. By comparing the maximum back face deflection, maximum back face velocity, plastic energy absorption, stress history and contact force, the corrugated sandwich plate with the gradually graded core has a better overall performance.
The parametric study on unit-cell corrugated and trapezoid sandwich structures with given mass and various core arrangements subjected to idealized air-blast loading is also carried out. The sandwich structures with graded cores can prevent the structure to get fully crushed. It is also shown that the trapezoid sandwich structures have larger impact tolerance, but the trapezoid sandwich structures are more sensitive to the initial geometric imperfections than corrugated sandwich structures.
Due to the benefits of the graded cores, a modified rule of mixture and linear strain-rate dependence are used to derive the rate-dependent elastic-plastic constitutive relation for functionally graded (FG) material. The derived constitutive relations are implemented in ABAQUS/Explicit through a VUMAT subroutine to simulate the dynamic response of a FG plate subjected to shock tube loading.

Play the Sicilian Kan

The Kan is an ideal choice as an opening weapon against 1 e4, as it is one of the easiest variations of the Sicilian to learn and play. This is because, unlike some variations of the Sicilian, you don't need to memorize loads of opening theory in order to be successful. The Kan is relatively theory free in the traditional sense, and success is more likely to occur through the understanding of development systems and a deep study of the tactical and positional ideas for both sides.

In this book Johan Hellsten draws upon his vast experience in the Sicilian Kan, revealing his secrets and showing how Black can adopt this opening and play it with confidence. He provides the reader with a dependable repertoire, demonstrating what to do in the main lines as well as how to deal with White's tricky alternatives.

 

  • Detailed coverage of an easy-to-play Sicilian
  • Includes answers to all of White's main options
  • Packed with original ideas and analysis
  • Written by a renowned Kan expert
