As a result of the increasing demand of energy especially the electricity , all
countries in the world headed towards depending on the alternative energy instead of the
fossil one , one of these alternative energy is the wind energy which is genera
ted by wind
farms include a sufficient number of aerobic fans according to the required power .
In Syria , We don't deepened on This alternative energy , but the ministry of
electricity with meteorological drew and issued atlas of the wind in Syria. These forms are
distributed in five regions on the mainland according to the energy that could be generated,
without taking the Syrian territorial water and the continental shelf opposite the Syrian
shores into account.
So that we worked on drawing, identifying and creating an invest mental map for
wind farms on the Syrian shores situating at the following locations: 1.Raas Al-Bassit، 2-
Al-Snober،3- Al-Hamidieyd
After monitoring the wind ,currents and the hydrodynamic effects and forces in the
sea as important requirements which are taken into account for designing the foundations
and bases of the offshore wind fans to choose the best places for building the offshore wind
farms to give additional electrical energy , clean and friend of the environment.
The purpose of this research is issuing an Atlas of wind including study of all regions
in the Syrian Arab Republic, especially the off shore and on shore areas within the
territorial water to determine the economic returns for different sites all
over the country
where everyday could be invested in each one, and set perceptions and measurements in
the Mediterranean about currents, waves and wind so as to choose the forms of offshore
wind fans on the Syrian coast.
Using of the Syrian territorial water and shore as a site to build wind farms is a way
for facing the lack of available areas on land, staying away from the noise of towers fans
rotation by this study, the sites which could be used for generating electrical energy were
determined at the minimum speed in 4.5 m/sec, which is taken as an indicator to determine
the sites depending on the measurements of wind speed and direction from the research
centers in Cyprus and Greece.
The horizontal Join beams with the slabs of reinforced concrete play the, the role of horizontal shear walls on the building height, Thus, the horizontal beams, columns and shear walls work together to form, the vertical resistance and horizontal loa
ds resulting from wind pressure or the intensity of earthquakes As a result to the great importance of the work of the join beams between wings of shear wall in the carrier wholesale of armed concrete، we have conducted experiments on shear wall and the result experiments compare with theory scientists and researchers in high- buildings. Been compared join beams with moment of stiffness constant in the level of its confluence with wings shear walls (Hold the forces of resistance horizontal dynamic plasticity in stage). And join beams in the form of crowns with moment of stiffness variable in the level of its confluence with wings shear walls.
We suggest a new theory with relationship for the change in the moment of stiffness join beams with crowns between wings of shear wall from reinforced concrete. Extract the experimental results and
compare them with the proposals of the new theory, and computational methods for global theories on the subject of search
And the impact of the work of the join beams with crowns between wings shear walls on the horizontal loads external pressure intensity of earthquakes or wind.
