steel design

Top chord members are carrying

• Tension members

• Compression members

Bottom chord members are

• Tension members

• Compression members

sag tie is the central vertical member of the truss used to reduce the moment due to self weight in the long middle tie member and also to reduce its resulting deflection.

• True

• False

Self weight of

AC Sheeting, GI Sheeting, purlin,Bracing

• 100-120,170-200,100-150,50

• 170-200,100-150,100-120,20

Self weight of truss

If both span and spacing of truss given

• 20+6.6L

• 10(L/3 + 5)*S/4

LIVE LOAD

if slope θ=20deg

• 750N/m2

• 750-(θ-10)*20 N/m2

Which code specify wind load

• IS 875 part 1

• IS 875 part 2

• IS 875 part 3

how we will get basic wind speed from is 875 part 3 Appendix -------- and page ---------
