arched beam
(OP)
Hello everybody
I have a case I would like you to help me by giving me ideas of the best way to build or erect this beam (see picture attached).
It s a warehouse composed by those beams with 6 m distance between 2 beams and covered by a metal cladding supported on steel beams or precast light slabS.
Has anybody did a similar project.
My questions are:
( most important question)- WHAT IS THE BEST WAY AND ECONOMICAL WAY TO BUILD THOSE BEAMS ( in total we have a length of 240 m which means 41 arched beam)
( secondary question ) - The calculation of the interface between fondation and this arched beam ( Freyssinet articulation ) ( see picture)
Many many thanks and sorry for my english

RE: arched beam
sure
I thought about it
How would you erect the beam? by a crane. With this conception it will involve 2 cranes for each part. May be if we put a vertical scaffolding in the middle to support the half beam !!
Have you done this before ?
many thanks

... but I can't make sense of the Freyssinet joint detail.

RE: arched beam
Erection with a single crane and a central scaffold support is a possibility, but that's a huge arch so you'll need to be very careful with all your details. Check deflections under self weight carefully, with generous allowances for creep, shrinkage and differential temperature effects, epescially if you are lifting when the concrete is young (but precasting and storing for a least a month would avoid putting young concrete under final load conditions)
What are you proposing at the crown? A pin joint is probably the way to go.
Good luck!

I m working on solutions and i will write you very soon what is the conception selected.
I really thank you guys
