Volume 42, Issue 6 , December 2008, Pages 723-737

https://doi.org/10.22059/jac.2013.7792

Abstract
  In this research, using the Modified Compression Field Theory (MCFT), a new truss based model is proposed to predict the behavior of reinforced concrete coupling beams with diagonal reinforcement. The model is able to consider the effects of shear and axial forces and bending moment, simultaneously. ...  Read More

https://doi.org/10.22059/jac.2013.7793

Abstract
  A water distribution network is one of the important parts of infrastructure systems. The efficient management and proactive planning of capital investment of these assets are fundamental for efficient and effective service delivered by water companies. The direct economic costs (i.e. rehabilitation ...  Read More

اثر عامل حالت در بهبود پیش بینی رخداد نوار برشی در خاک های دانه ای

Ali Lashkari; Manouchehr Latifi

Volume 42, Issue 6 , December 2008, Pages 775-783

https://doi.org/10.22059/jac.2013.7795

Abstract
  The capability of sand constitutive models is remarkably improved by taking into account the effect of soil state in their formulations. In this study, it has been shown that considering the effect of soil state leads to better simulation of soil instability of shear banding type. To this aim, constitutive ...  Read More

روش مسیر یابی ذره به منظور پیش بینی حرکت نفت در دریا

Mohsen Naghibi; Morteza Kolahdouzan

Volume 42, Issue 6 , December 2008, Pages 795-807

https://doi.org/10.22059/jac.2013.7796

Abstract
  A two-dimensional two-phase numerical model is developed to predict transport and fate of oil slicks which resulted the concentration distribution of oil on the water surface. Two dimensional governing equation of fluid flow which consists mass and momentum conservation was solved using the finite difference ...  Read More

(بررسی فنی و اقتصادی روسازه های بتنی در خطوط راه آهن مسافری (یادداشت فنی

Volume 42, Issue 6 , December 2008, Pages 705-711

https://doi.org/10.22059/jac.2013.7797

Abstract
  Ballast as a part of the railway system plays an important role in the operation of the railways and also has a great impact on repair and maintenance activities. Hence most of the repair and maintenance activities in traditional railway systems are due to the defections in the ballast layer and therefore ...  Read More

قالب جزء محدود پوسته استوانه ای

Mohammad Reza Pajand; Reza Khajavi

Volume 42, Issue 6 , December 2008, Pages 713-721

https://doi.org/10.22059/jac.2013.7798

Abstract
  Curls and curves of a shell interweave its various strain modes and link them together. This interactional behavior has yet frustrated all attempts for the construction of shell templates, which needs for an individual element test in traditional approaches. Such a test fails to work for shell elements ...  Read More

بازتاب و شکست موج SH در مرز ناهموار بین دو محیط ایزوتروپ جانبی

Navid Shad Manaman; Morteza Eskandari Ghadi

Volume 42, Issue 6 , December 2008, Pages 751-763

https://doi.org/10.22059/jac.2013.7799

Abstract
  The existing theory for wave propagation through a soil layer are not compatible with the real soil layers because in the theory the layers are flat and the sub-layers are parallel, while in real the soil layers are not flat and they may not be parallel. Thus, wave propagations through a corrugated interface ...  Read More
