ii Testing for establishing soil and pile !odulus

c) Structural "aterials and S#ste!s $i %erfor!ance of different structural s#ste!s& What le'els of ductilit# are

achie'able in the lateral force resisting s#ste!s being constructed in India? What should the 'alue of (

be?

ii #brid Structural S#ste!s and their beha'iour

iii *eed for redundanc#

i' Structural plan and 'ertical irregularites: What t#pes and degrees of

irregularit# are acceptable? What are the special design re+uire!ents? Special attention to be paid to

soft stor#, torsinal eccentricit#, transfer girders, and plan-offsetting of lateral force resisting s#ste!

between an# two consecuti'e stories

' "aterials: Concrete, steel, co!posite

d) General %ara!eters of Tall Buildings $ Geo!etric %roportioning

i eight and spect (atio

ii General .istribution and area of ertical and 0ateral load carr#ing ele!ents

as 1 of plan area for concrete and steel structures

iii "in re+uired stiffness of building

i' %eri!eter offset to a'oid pounding

f) 2se of "asonr# partition walls in tall buildings

i ow to include in anal#sis?

ii Should the# be isolated fro! structure or not?

iii If the# !ust be isolated what t#pe of detailing?

g) "odeling and nal#sis

i ppropriate "odelling tools and soft ware for elastic, inelastic design for

different s#ste!s and ele!ents

h) Structural Irregularitiesi Should structural s#ste! transfer be allowed in tall buildings? If #es what

are the li!itations to be obser'ed?

ii Soft store#, Wea3 Store#

iii ow to deal with torsional irregularit#? ow !uch !a4 !odal !ass !a# be

e4cited in torsional !odes of 'ibration?

ii What are the wind tunnel tests that should be carried out and to what

effect? ow to account for future buildings in the neighborhood in the la#out and configurtion of

ad5acent buildings in the wind tunnel?

iii What are the results to be as3ed fro! the WT testing agenc#?

i' ppropriate .a!ping alues
