TSE?? StructureMag had an article on their new office a few years ago. Love what they did there, I've always been a sucker for projects that highlight structural elements.

Interesting question. The inertial forces generated by the podium level modular floor will absolutely contribute to the overall shear the anchors need to resist, to not include them in the anchorage design would be unconservative. On the other hand I would think long and hard about including...

Do you typically check creep on composite floor systems? Months ago I asked one of the engineers I work under if it was something I need to be concerned about and he said it's negligible. Not saying it doesn't exist, but I'm honestly curious if any of you out there are checking this?

Well there you have it, I detract my logic. Jittles appears to have your answer.

That's a good question - just thinking out loud I would reason the two stage analysis leaves it open to interpret the the upper portion as effectively being a separate structure, eg the design would be "essentially" the same were it on the ground. Now I would ask myself the question - would I...

ASCE 41-13 has a list of lower bound values you can assume without testing - 1000 psi for clay brick I think. Similar to Celt83 I've seen compressive tests for existing brick assemblies come back around 800 psi - the actual brick tested upwards of 1100psi but the mortar failed around 800psi. Not...

HSS shapes are perfectly acceptable as column elements in SCBF pending they meet the ductility requirements. Table 1-5 in AISC 341 can give you a quick idea of what shapes meet those requirements. I've never used HSS elements as beams in a SCBF but again I would imagine as long as the shapes...

By looking at the architects wall and floor assemblies. It can depend quite a bit on the intended usage of the space. I’ll always double check and confirm floor assemblies with architects. Last thing you want is to assume and find out later the architect has an 1-1/2” of gypcrete topping and you...

What's to gain giving up one just to exclusively adopt the other? Both have their inherent strengths and weaknesses, and neither material is guaranteed to always be the better choice, it depends on the situation. From an environmental standpoint I think wood has a significant advantage: - it...

Deker, Thank you so much, yes that was the source of my confusion. Thanks for the response everyone, much appreciated

NCMA TEK 14-4b has this equation for the maximum reinforcement ratio in CMU shearwalls: I'm hoping one of you can help me understand how this equation isn't blowing up and going to infinity. The way I'm understanding it, that equation is dividing by 0 once my steel reinforcement reaches it's...
