Baretired, using the shear flow k/in by formula you provided in order to design the weld would you ratio the shear flow into 3 webs based on the thicknes of plate, the center web is cont connected the remainder will design the welds for outside plates.

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

I undrestand that there will be arching action, but I just don't feel right not installing a lintel to support the wall. (specialy I know the wall will crack at the corners) csd72 you mention you have done few of this openings, could you please post a sketch on how did you detail the opening...

msqumred48 I could not undrstand (channel after-set bolt) also if the channel is set under the panel in plane of the wall how would you connect it to the steel column. I would appretiate if you could sketch this detail, it will be easier to undrestand. Thank you in advance.

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...

Thank you, dcarr82775

To all I have found PNA and the C=T (area * FY 50 or Area*36) based on the material. Mn= C * d1 + T1 * d2 + T2 * d2 The PNA is in the web of the wide flange beam C= 50 * A (the tee above the PNA part of upper W shape) T1= 50 * A ( the tee below the PNA- part of the lower W shape) T2= 36 * A...

I have wide flange beam Fy=50 ksi reinforced in the bottom flang with a WT Fy=36 ksi, I am trying to find Mp, Z etc. to check the size

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.
