A. Davaran; J. Hassanzade; N. Tolouei Molan; M.J Rafizadeh

Volume 2, Issue 1 , Winter 2008, Pages 1-6

http://dx.doi.org/10.22061/tej.2007.1281

Abstract
  In this paper, the nonlinear-non-elastic behavior of the braced frames of the SCBF Special Center is compared with the BRBF anti-arc bracing brackets. Different structures with different numbers of floors, which were previously designed according to the existing regulations and the recommended behavior ...  Read More

2. The use of sediment simulation model in determining the service life of Ekbatan Dam reservoir

S.A. Mir Bagheri; S. Boudaghpour; S.A. Hashemi Monfared

Volume 2, Issue 1 , Winter 2008, Pages 7-14

http://dx.doi.org/10.22061/tej.2007.1282

Abstract
  Erosion and sedimentation phenomena have many destructive effects on the environment and human life. One of their most important effects is to reduce the volume of dam reservoirs. When the tank can no longer perform the intended service, its useful life is over. So far, several models have been proposed ...  Read More

3. Investigating the effect of compressive reinforcement on the flexural strength of sections based on ACI 318-05

R. Morshed; A. Eslami

Volume 2, Issue 1 , Winter 2008, Pages 15-19

http://dx.doi.org/10.22061/tej.2007.1283

Abstract
  According to pre-2002 editions of the ACI 318 Regulations, in normal bending sections, it is not necessary to use a compression reinforcement before reaching the maximum tensile reinforcement and it is not necessary to use it to help the bending strength of the non-economical section. By changing the ...  Read More

4. Anisotropy of mechanical properties of sandstone

M. Hosseini

Volume 2, Issue 1 , Winter 2008, Pages 21-31

http://dx.doi.org/10.22061/tej.2007.1284

Abstract
  The Anisotropy in the mechanical properties of the rocks is due to the presence of discontinuous plates in them. This paper examines the Anisotropy of the mechanical properties of sandstone. Due to the abundance of sandstone in Iran and the implementation of many projects in this type of rock, ...  Read More

5. Direct numerical simulation of two-dimensional and non-compressible boundary flow using compressed finite difference method

M.J. Maghrebi; A. Zarghami; M. Feyzabadi Farahani

Volume 2, Issue 1 , Winter 2008, Pages 33-42

http://dx.doi.org/10.22061/tej.2007.1285

Abstract
  The dimensionless Navier-Stokes equation is solved in a rotational form for the flow of a two-dimensional boundary layer of plates by a direct numerical method. Considering the speed profile at the input of the computational domain, the thickness of the boundary layer has been used as the characteristic ...  Read More
