The behavior of Electric transmission tower, as it rises higher, is more vulnerable to earthquakes than to wind and its structural stability is determined by the wind load. As wind does not blow at an constant rate over time, rotation take place as a result of wind that changes by obstacles such as buildings, trees, terrain. To consider these effects, wind load is multiplied by a coefficient, which is called Gust factor. And model (765kV, 345kV, 154kV) were selected, depending on the type of Electric transmission tower. MIDAS (Gen) 6.3.2, structural analysis program is used for the purpose of the interpretation of the structure, wind load mixture relying on the wind load was applied as parameters, span. In this paper, it is represented that the Gust factor in the height and width of Electric transmission tower, stiffness and natural frequency is focused.

SC(steel plate-concrete) structure is recently used in nuclear power structure because of its efficiency of construction. In this study, an analytical study to investigate the behavior and strength in wall-slab connection of SC structure was carried out. Finite element analysis was performed and the result of the analysis was well matched with the experimental result. By varing the thickness of shear plate and friction coefficients and distance of applied load from the wall, the influence of the parameters on the joint strength and failure modes were examined. Finally. It was confirmed that the joint strength formula proposed in previous research gives conservative results.
