Week 4 Challenge

Q.1

Answer:-

AIM AND INTRODUCTION : DESIGN OF BEAMS

PROCEDURE : SECTOIN CLASSIFICATION CALCULATION OF THE FOLLOWING BEAMS

For built up box d/t=960/12=80 Hence the section is semi compact

PLASTIC compact semi compact

for RHS section FLANGE b/t 29.3ε 33.5ε 42ε

web d/t 67.1 ε 84ε 125.9ε

nbsp; d/t = 130/10 = 13 section is plastic

nbsp; PLASTIC compact semi compact `

• Double angle (Back to back) – 2 x ISA 75x75x6 d/t 9.4ε 10.5` 15.7
• 75/6=12.5 hence semi compact section.
