Tutor description

A tentative model of 170m tower(height as given in received drawing) is created in STAAD and tentative property is assigned to the structure. Assuming only wind pressure acting on the structure varying from 1kn/m2 at 50m level to 2kn/m2(ignoring the self weight command in staad) at top and analyzing the structure, reaction received is +/- 892 Kn (vertical) on each support as shown in figure 1 below.

Geometry Study of Lattice TowerA tentative model of 170m tower(height as given in received drawing) is created in STAAD and tentative property is assigned to the structure. Assuming only wind pressure acting on the structure varying from 1kn/m2 at 50m level to 2kn/m2(ignoring the self weight command in staad) at top and analyzing the structure, reaction received is +/- 892 Kn (vertical) on each support as shown in figure 1 below.Purpose of the analysis:The purpose of this analysis is to identify the best geometry configuration for the tower. For the lower stool with the width of 28 meter, the member length are higher. The maximum members should participate in the load taking mechanism. The slenderness of the member should be checked about both the principal axis.Data:-Base width of the tower considered is 28mNote:HEIGHT TO WIDTH RATIOBook on Communication Tower by Brian.W.Smith gives height to width ratio between 8:1 to 5:1Thus assuming ratio as 6:1, we get base width for height of 170m tower as 170/6 = 28.3 m(which is ok)Reference:http://books.google.co.in/books?id=m-Uhn_O7O08C&pg=PA75&lpg=PA75&dq=height+by+width+ratio+for+lattice+tower&source=bl&ots=en670lJGMP&sig=UIsxrqMgKkP6Xppe_iz7MMJLGho&hl=en&sa=X&ei=VUnFUoGSOcG4rAfstICoBQ&ved=0CC0Q6AEwAA#v=onepage&q=height by width ratio for lattice tower&f=falseNote:Basic geometry for the tower is taken from the Indore Doordarshan tower. The geometry is noted during the site visit of Mr. Mahesh Varma to Indore.
