    I have a building near a coastal area that has the lower portion of the metal wall studs heavily corroded. The metal stud track and lower portion of studs have corroded to a point that the web and flanges have lost large sections of their areas. We are in process on investigating what are the...

    CMU wall to Wood Wall Connection

    Yes, the tie beam at the top of the masonry wall...it frames into to perpendicular masonry walls at either end, which then are perpendicular to the exterior walls.

    Residential Wood Deck Design Wind Loads?

    In looking over the DCA6 for Residential Deck design, no mention is made of wind loads. I am designing a residential wood deck around a large pool area 4' of the ground, thinking of applying the open structure wind pressures on the deck structure, but I am unable to find any reference that may...

    CMU wall to Wood Wall Connection

    The roof rafters span from side wall to ridge. The ceiling rafters span from sidewall to sidewall and are lapped over the interior wall location, bearing over the interior masonry wall. The wall only takes the ceiling joist dead load and a 10 psf attic live load. The wall will be replaced from...

    IRC Plumbing Table WSFU (Max Velocity in PEX Piping)

    I typically size of my water supply lines for both commerical and residential structures using WSFU. Does anyone know the maximum pipe velocity and assumbed pipe materials used in the IRC plumbing section? I have compared the values to the NSPC and those tables (based on different piping...

    Steel Bar Joist Supported on Steel Ledger

    The joist roll-over capicty might be an idea, my shear loads are pretty low. It may over stress the anchor bolt connecting the angle to the wall. I'll examine that option. The continous angle would provide my sidelap fastening at the deck. Thanks for the idea JAE.

    I am workng on an addition that has three walls being added to an existing structure. Do the layout of the roof framing plan I am not able to tie in the addition to the existing structure. I looked at the building as a three-sided diaphragm via a Vulcraft publication that I have. My question is...

    Steel Bar Joist Supported on Steel Ledger

    Thank JAE for the response. I also had the thought of having an additional continous angle directly underneath the deck anchored to the side of masonry wall. In other words, a larger steel ledger to support the bar joist for gravity and uplift loads (lets say 6x6-LH series requires 6" bearing so...

    Steel Bar Joist Supported on Steel Ledger

    I have an LH series steel bar joist spaning about 40' spaced at 4" o.c. The architect is sugguesting to to support the bar joist via a steel ledger attached to the side of masonry wall. While it would facilite the construction of the wall, I am concerned about the viability of this connection...

    Masonry Shearwall

    Thank you for the response. I checked the wall for out of plane loads and in no way does it work. I may have to look at a pilaster arrangement.

    Masonry Shearwall

    I am working with an architect on an addition to a restuarant. One of the shearwalls has various size openings but the width of the shearwall segment elements is only 16". Can this actually be design as a masonry shearwall, I was thinking at this point it would resemble more of a frame.
