Shielding effect on multi-frame structures

Shielding effect on multi-frame structures

Shielding effect on multi-frame structures

hi, i am preparing a design specification/criteria for our new project.

for shielding effect of multi-frame structures (e.g., a very long piperack), i am looking for a shielding effect formula to be applied. i was away from design work for 8 years. i remember using the shielding effect formula way back 15 years ago when i was working for oil/gas projects using both ASCE and BS-CP3, but i could not find such provisions in ASCE 7 now. tables 6-9 and 6-10 of ASCE 7-95 shows the coefficients used, but no procedures explained. this is clearly explained in BS-CP3, Chap. V, but that code is not applicable to this project.

im still looking for it, ill be glad if someone can share some thoughts.

Use the Wind Loads and Anchor Bolt Design for Petrochemical Facilities which can be ordered from their publications website.
