Re: Equivalent concrete thickness for masonry

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Table B-3 of Amrhein's "Reinforced Masonry Engineering Handbook", 1st edition, 1st printing, 1972.

According to a footnote:  "Equivalent solid thickness means the calculated thickness of the wall if there were no hollow cores, and is obtained by dividing the volume of solid material in the wall by the face area of the wall."

I am analyzing an existing building that had reinforced masonry walls for lateral force resistance and I was trying to compute an equivalent concrete thickness for the same in order to model in ETABS.
Are there any standard formulae that can be used to arrive at the eq. thickness or is it based on a trial and error basis calculation of the lateral stiffness?
