ارائة مدل اولویت‌بندی علت‌گرا جهت تعیین قطعات خطرناک جاده‌ها برای عابرین پیاده

Mahmoud Saffarzadeh; Vahid Abolhassan Nejad; Amin Mirza Boroujerdian

Volume 42, Issue 4 , August 2008, Pages 457-467

https://doi.org/10.22059/jac.2013.7763

Abstract
  One of the most important and effective factors in prioritizing high accident prone segments of roads for pedestrians is accident cause which up to now has been neglected in current methods. Since accidents are not additives due to various reasons, prioritizing these segments without considering the ...  Read More

https://doi.org/10.22059/jac.2013.7765

Abstract
  One of the major purposes of optimization in civil engineering is to perform a suitable design for the structure. This goal has to fulfill technical criteria and contain the minimum economical costs. Building frames are of the most customary civil engineering structures. Therefore, optimization of these ...  Read More

بهینه سازی سازه های فضاکار بادرنظرگرفتن احتمال خرابی اعضاء و گره ها به کمک الگوریتم وراثتی اصلاح شده

Mohammad Reza Ghasemi; Mohammad Reza Mostakhdemin Hosseini

Volume 42, Issue 4 , August 2008, Pages 477-485

https://doi.org/10.22059/jac.2013.7766

Abstract
  Due to the probabilistic nature and uncertainties of structural parameters, reliability-based optimization will enable engineers to account for the safety of the structures and allow for its decision making applicability. Thus, reliability-based design will substitute deterministic rules of codes of ...  Read More

بررسی اثر پارامترهای خاص گسلش و موقعیت مکانی ساختگاه بر مشخصات پالس حوزه نزدیک گسل

Mohammad Reza Ghaemmaghamian; Behnam Khalili

Volume 42, Issue 4 , August 2008, Pages 487-496

https://doi.org/10.22059/jac.2013.7767

Abstract
  The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area ...  Read More

درکنش سد و مخزن در دامنه زمان به وسیله روش انتگرال حلقوی منفرد مجزا (DSC)

Kianoush Karimi; Reza Attarnejad

Volume 42, Issue 4 , August 2008, Pages 497-508

https://doi.org/10.22059/jac.2013.7768

Abstract
  In this paper, time-domain dynamic analysis of dam - infinite reservoir is studied. A numerical method, discrete singular convolution (DSC), which seems to be efficient and simple, has been used to model the mixed boundary conditions. After a brief introduction, DSC is applied to model the equation of ...  Read More

معرفی ستون جدار نازک توخالی ساخته شده از ورقهای فولادی موج‌دار و بررسی رفتار لرزه‌ای آن

Seyyed Rasoul Mirghaderi; Seyyed Mohammad Saeed Sobhan

Volume 42, Issue 4 , August 2008, Pages 509-521

https://doi.org/10.22059/jac.2013.7769

Abstract
  Thin-walled hollow steel columns, either circular or box shaped, are commonly used as piers in bridges. Recent earthquakes, e.g. Hyogoken-Nanbu or Kobe 1995, on the other hand have shown that these columns are vulnerable to damage when subjected to earthquake loading. This paper presents a new innovative ...  Read More

https://doi.org/10.22059/jac.2013.7770

Abstract
  Large deformation causing damage due to uplift force is generated in buried pipeline located in shallow trenches in marshes and saturated soils. In this paper, existing common methods of pipeline anchorage are discussed and considering advantages and disadvantages of these methods, a new method of pipeline ...  Read More

روابط جدید زمان چرخه بهینه برای تقاطع‌های پیش‌زمان‌بندی شده مستقل با تغییر رابطه وبستر براساس روش HCM 2000

Volume 42, Issue 4 , August 2008, Pages 419-429

https://doi.org/10.22059/jac.2013.7773

Abstract
  When the degree of saturation at intersection approaches one, Webster’s optimum cycle length equation becomes inapplicable, because the cycle length will becomes very big when the degree of saturation approaches one and will be fully unrealistic when the degree of saturation becomes greater than one. ...  Read More
