Urgent: Help on support bracing

Urgent: Help on support bracing

Urgent: Help on support bracing

(OP)
Hi,

The structure (attached picture) is 15 m long and is made up of OD 12" x 16 mm W.T. cloumns and OD 8" x 8 mm W.T. braces. The structure is meant to support 25 mt valve on the top. Could anyone please tell me, if the bracing proposed is acceptable. I did a API code check with vertical load of 25 mt and wind load, the maximum ratio obtained is 0.36

My client is insisting me to add diagonal braces. Should I need to add diagonals as well? Can the proposed system be called as nodal bracing? A quick reply will be appreciated as I am on a dead line for fabrication.

Thanks

RE: Urgent: Help on support bracing

Your client is absolutely correct. The structure is not laterally stable unless you either design it as a moment-frame where the members and joints are able to sustain moments and shears from lateral forces or add diagonal members from joint to joint designed for the same lateral forces.
