Shear capacity equation for 100 year old brick piers
Shear capacity equation for 100 year old brick piers
(OP)
Hi everyone,
Other than performing testing on mortar strength, I will like to predict the shear capacity of an unreinforced brick pier of a building constructed about 100 yrs ago. I have the UBC shear capacity eq. for reinforced mansonry walls and will like to use it, by just setting the shear capacity of reinforcement equal to zero. Is this OK?, or is there any other eq. that only calculates shear strength of unreinforced masonry walls?

Just make sure you use FEMA 356 in its entirety, great document but somewhat complicated and cumbersome but you really get the most out of the exisitng structure.
I have used it for many upgrades of all types, you will also need to make sure your jursidiction will approve its use, Portland, Oregon allows its use with an approval.

You want "Design and Construction of Stone Columns", 1985, FHWA-RD-83-027, PB85-215416/AS... For some reason listed as a Ground Improvement...

The engineers with PWGSC are some of the best bridge engineers in the world when it comes to existing bridges. Our National Capital is a monolithic stone architecture museum, unlike the american capital which always strikes me as somehow cold and polished, but absolutely stunning (as, of course, it was intended). If you're looking for some expertise in the area, I would suggest sending them an e-mail. They're very friendly and usually more than willing to help, government department or not. They will not consult for external organizations, so expect to have their help limited to suggestions and tips by telephone and e-mail.
I've done a few of these analyses myself over the years, just remember that the quality of the pointing makes a big difference. With stone that old, it almost certainly is not cementious grout. Make sure you match your grout for any repairs! If your grout is more stiff/stronger than the original grout, or even worse stronger than the stone themselves, you can be in for big trouble.
Good luck! Let us know how it turns out...

If I can put my finger on it, I'll post the link...
