I have a beam need to be reinforced , I have to use two side plates as shown in the attach sketch , the plates are the same size welded to a wide flange beam ,is the weld calcs shown in sketch correct ? specialy the Q calcs for VQ/I
Thank You
New opening will be cut (10 ft high x 10 ft wide) into an existing load bearing tilt up wall, I have attach a sketch and a support system with steel tube as a header beam and steel colmuns spaning from foundation to roof.
My idea is as follows:
1- The header beam will support the gravity load...
For a given build up section with different Fy for each plate , I have the following questions:
1- To calc. PNA , The area * Fy above PNA = area * Fy below PNA.
2- To Calc Z ,sum off all (individual area* (distance form CG of each elemant to PNA))above and below the the PNA.
3- Mp...
I have the following questions on 2008 NYC Building code
section 1609.6.3.3 Components and cladding:
1- Could this section be used to design parapet walls (wind load = 30 psf) ?
2- if yes, is there any building height requirements. (other then section 1609.6.1 Scope)
For Ecc. Footing design with resultant load outside the kern
Is ther any design guide or code ref. about the min. ratio requirements between bearing lengthh vs actual footing length (L2/L1)?
see attach sketch.
