ABSTRACT 
A transmission tower is a space truss and is an indeterminate 
structure. Increasing demand for electricity can be made more 
economical by developing different light weight configuration of 
transmission line tower. Literature survey revealed that comparative 
study of different types of tower. In all of the previous work Steel 
Transmission tower is considered but none of them defined the 
variation caused due to Different Type of Pylon using different 
Software for Seismic Zone III. Present study reports the design and 
analysis of steel transmission line towers performed static and 
dynamic assessment of transmission line tower. The investigation and 
displaying of tower is executed the utilization of FE based absolutely 
STAAD Pro software. Effect of wind and earthquake loads was 
studied and the results so obtained were compared for wind zones III 
for four legged tower.

INTRODUCTION 
Transmission line is a coordinated framework 
comprising of transmitter subsystem, ground wire 
subsystem and one subsystem for every class of help 
structure. Mechanical help of transmission line 
addresses a huge segment of the expense of the line 
and they assume a significant part in the solid force 
transmission. They are planned and developed in wide 
assortment of shapes, types, sizes, setup and materials. 
The supporting construction types utilized in 
transmission line by and large can be categorized as 
one of the three classes: cross section, shaft and 
guyed.  
OBJECTIVES  
 To Study of high tension tower with three 
different pylons using STAAD PRO V8i 
Software. 
METHODOLOG 
separate models are created on STAAD PRO V8i 
Software to check the suitability of different type of  
 
pylons for transmission towers subjected to wind & 
seismic loads.

CONCLUSIONS  
The tower with angle section and pylons has the 
greater reduction in weight after optimization. 
Different type of pylon is economic to use in this type 
of steel transmission tower. 
Some of the key points of conclusion: 
 Model II shows least displacement i.e. 78.96mm, 
19.96 mm, 291.28 mm in X, Y & Z directions as 
compare to Model-I and model-III. 
 Model II shows shear force in all conditions i.e., 
527.45 Kn, 0.728 Kn & 1.426Kn in X, Y & Z 
directions. 
 Model II shows least bending moment in all i.e. 
0.004Kn-m, 1.292Kn-m, 0.721Kn-m in X, Y & Z 
directions as compare to Model-I and model-III. 
 Hence Model II shows better results in terms of 
displacement & bending moment.
