Hurray and congratulations. I have noted before with this great group, that in the field, we see product failures about five years before the design professionals catch on. Similarly, they say, when products fail in Europe, they market them in the US of A.

That was in my post-Soleri years, and the hands-on approach to construction I gained while working with him really made me wonder what the point was for those little threads of steel in the brick mud. Questioning stuff like that proved to be life changing. On day, after the bosses had spent all morning arguing and looking at masonry catalogues and speculating about what they could actually specify to have purchased in our small BC town, seeking how to detail rounded pilasters for a simple concrete block apple packing house (storage building), at coffee break the post-Soleri kid at the back desk said, "Why not ask a mason here in town. He would surely know what is available and how to make those pilasters?" The head arthrititect stood up like a ram rod and said sternly, "We don't ASK the trades, we TELL them!" That was the day I decided I would never draw something I didn't understand. A month later I went back to Arizona, became a member of the Arizona Designer-Craftsman Guild, specialized in architectural craft through carving and casting in diverse materials, created the sand cast candle phenomenon , led a curious life of experiences and even eventually got back to the design boards and supervising high rise construction, but at least by then I knew every detail I was responsible for, and have lived happily ever since. cp in bc ----- Original Message ----- From: "Becker, Dan" <[log in to unmask]> To: <[log in to unmask]> Sent: Thursday, February 07, 2008 8:26 AM Subject: Re: [BP] The rare serious question frm ][<en > -----Original Message----- > From: Gabriel Orgrease > Sent: Tuesday, February 05, 2008 3:02 PM > > 1955, brick church, Mineola, LI. <snip> Brick walls > approx 25' in height in 1950's colonial motif architecture. > > We noticed in the field of the wall horizontal mortar joints > deteriorated and repointed (hard mortar shell repointing) > that were in an odd location, one line below the arched windows, > one line above.

And play it is. Not licensed. Steel is a tension element. Why would the designer propose a tension element in this location? If I read it right, this is two continuous bands: one above the window openings (how many courses above?) and one below (same question of proximity). They must have felt there was some force in that area that required a tensile treatment. What were they trying to hold together? In analogy it strikes me like two giant rubber bands around the building horizontally flanking the window openings holding the "box" together. They must have felt for some reason the window openings would introduce a "stretching" or "sagging" or "bowing" force that needed to be counteracted by a tension element. If the brick is a veneer, what is the structural frame of the building and walls? Steel? Wood? What structural system is it that the windows are punching a hole through, introducing some force that they felt that the brick veneer needed a tensile element to resist or counteract? Brick veneer is not structural; this is not a reinforced masonry system we're talking about, so why add reinforcement? I agree it is very weird, and stainless is a wise replacement. I wouldn't take them out without a better understanding of why they are there. It's possible since they are so odd that they were somebody's stupid bright idea and do not serve any real purpose, taking care of some imagined problem, but you never know. Anybody like Ralph got a 1950s-era Architectural Graphic Standards laying around that can be looked at to see if it has a standard detail for this? Would Tom Jester's Twentieth Century Building Materials book shed any clues? Let no serious question go unanswered, even if it is a useless answer. Seriously useless.
