In this research, the danger and the horizontal force effects on the
engineering structures will be explained, and we will focus on the
horizontal winds force effects on the bridges, the high buildings and
special engineering structures. The resul
ted loads will be analysed and
evaluated in both static and dynamic methods. In the end of the
research, two practical examples will be shown for the two methods.
. In this research, a study of a model of reinforced concrete elevated
water tank, with capacity of 900 cubic meters, supported with
frame system is carried out using finite element method (FEM).
The liquid mass contained in the container is model
ed as the sum of
two separated messes i.e. impulse mass and convective mass
following the recommendations of Eurocode 8 , 2006, for cases full
container. The second ones Gareane2011 method . The soil is
modeled using (FEM) with energy absorbent boundaries (dampers)
to prevent the combination of earthquakes waves.
This study aims at conducting a comparative study between the
Pseudostatic Approach that is based on the limit equilibrium theory
and the Dynamic Analysis using to the finite element theory using
Geostudio software.
In 2002, Zeyzoun Dam failure, that is an embankment dam located at the northwest of Syria, made a big Awareness of the effects of the lack of Geotechnical investigations and concern given to seismic design, geological conditions and location of the d
am. Zeyzoun dam location, in the vicinity of the Dead Sea fault system, emphasizes the importance of analyzing the effects of lithological stratum in dam foundations on dam seismic stability. This paper is concerned with the influence of a high permeable soil layer that has different static and dynamic properties, and exists at different depths in dam foundation. Geo-studio software, a Geotechnical program that applies the finite element method and can consider analysis like seepage, dynamic analysis and slope stability, used to build and analyse numerical models. The results of dynamic analysis showed rising of phreatic line level in dam body, amplification in dam dynamic response, increasing in pore-water and excess pore water pressure and decreasing in stability factors of safety, along with decreasing of the thin layer depth.
This research includes analyzing and designing of high water
tanks using elastic method. Also, analyzing the structural
supporting system using the Second Equivalent Static Method, then
analysis by using Linear Dynamic Method - Response Spectra
