Thank you both for the great information

Thank you

I'm looking at existing drawings for a building that was designed in 1957 and they have a note that all joists shall be 10LB15 which i'm assuming is a W10x15 but I'm not sure. I did a good deal of searching for this designation but couldn't come up with anything. Any help is greatly...

hokie66, The decking and railing will be Merbau and the beams will be glulaminated timber.

Thank you all for the helpful information

I have been tasked with designing a small pedestrian bridge with Merbau wood. I have to admit, I've never heard of this specie of wood and can't seem to find its properties. I have searched extensively but didn't come up with anything useful, so any help as to the design properties of Merbau...

Ingenuity, All the more reasons for me not to get involved in this project. Thank you all for the great replies

Great points. Thanks again

SkiisAndBikes, 1. The building is on the beach so it's salt air corrosion. 2. I don't know since as I mentioned I don't have any drawings. 3. I don't have that information either 4. No tendons have been broken as far as I could visually see, but I was hoping the x-ray would reveal the broken...

Thank you.

I just noticed that the 2012 IBC eliminated all the nail fastening values from Table 2306.3(1) and now only includes staples which have smaller shear values. Does anyone know the reason for this change or if I'm missing something? Is there a different table for values of nailed panels that I'm...

I got a picture of this joist from a client on one of my potential projects and was wondering if someone could shed a light on what kind of joist it is. I don't have the job yet so I can't take measurements or try to find a joist tag, I'm just trying to get an idea of what kind of joist I'm...

Thank you all for the input. I have advised the contractor that I am not allowing the use of puddle welds. I think it's a bad idea. Ron, you're absolutely correct, that's almost the exact thing he said :-)

I have always specified Hilti fasteners to attach deck to galvanized beams, but I've been asked if puddle welds could be used instead. My thought that it's harder to puddle weld to galvanized steel than it is to use the Hilti fasteners but the fabricator is telling me otherwise. Any thought on...
