![]() Transmission line towers carry heavy electrical transmission conductors at a sufficient and safe height from ground. In addition to the loads described above, there are others that intervene in the building, although they are evident only during the execution phase of the building, those loads that are forgotten and not taken into account, nor even the existing mandatory regulations CTE, EHE-08, in that first approach of load state for the calculation of the structure of the building, Figure 1, are there and have their direct consequences on the structure, ultimately on the useful life of the structure and the interaction with The rest of the elements that make up the building can cause instantaneous pathologies, medium and long term in the structures and consequently in the rest of the building with the effects derived from them, as permanent deformations that harden the building's habitability. ![]() The approach to the calculation of the structure of a building, apart from the geometry and its peculiarities always in the first instance, the first approach is to analyze the state of loads, according to current legislation CTE, to which the building will be subjected and In their respective plants and areas, these loads are defined in any of the regulations in force at the moment in Spain and almost all the professionals of the sector known for their application. Then, these two towers are designed and compared. It is to be noted that for optimizing any member section, the entire wind load computations have to be repeated and hence the analysis and design process simultaneously. Each of these tower members are then designed as an angle sections. A three-dimensional analysis of each of these different configuration towers has been carried out using 8i software. To meet this objective a 132kV double circuit self-supporting angle tower is taken with vertical and horizontal configuration of cross-arms. In this work, an attempt is made to make the transmission line more cost effective by changing the geometry (shape) of transmission tower. Moreover, the increasing demand of electrical energy can also be met economically by developing different light weight configurations of transmission line towers. So material saving in a single tower will lead to a considerable effect to the final cost of the project. A single transmission line consists of many transmission towers. Therefore optimization in design of towers can bring about significant economy in the cost of transmission lines. The transmission line towers constitute about 28 to 42 percent of the cost of a transmission line. With the increase in the transmission voltage levels, the heights as well as weights of towers have also increased and so as their cost. Tower constitutes a very vital component of transmission lines. ![]() Drift can be controlled by providing outrigger at optimum location of the building. The results shows that the tube structure and 'L' shape shear wall are more stable and does not have torsion irregularity and also the displacement is less compared to other general structures. ![]() In this present work all this points are considered and the results obtained are tabulated, graphs are plotted and compared. When seismic analysis is considered some of the major factors come into picture like lateral displacement, storey drift, and stability of columns in particular storey due to lateral forces and when the building is in irregular configuration torsion irregularity will also become an important factor. These models are analyzed for response spectrum method and wind load. Here, in this present work a particular type of irregular building with different structural forms are considered and seven models are developed in Etabs software with codal provisions. ![]() In one or the other residential and commercial buildings, there is always a trend towards taller and more slender structures. Nowadays there has been a considerable increase in the number of tall buildings. ![]()
