ANALISYS OF COUPLED SHEAR WALLS

[EBARRERA]

Hello fiends and colleagues of this forum...

I need for academical purpouses, the formulas to calculate the maximun displacement at the top of a coupled shear wall subjected to a triangular loading and also to a concentrated load at the top, using the laminar method (approximate) suggested by Riko Rosman, this approach is rewied at the ACI journal vol 61,June 1964, but i havent found this journal. If anyone can send me the formulas or send me any document where they appear, i would be really grateful, ive been trying to obtain those formulas on the internet without success.

thank you in advance for your help...

Perhaps try the Moment Frame & Shear Wall Engineering forum
(forum726).

thank you dbuzz, I posted this same topic on the Moment Frame & Shear Wall Engineering forum, but no one have responded so far...

I remember 'wading' through the non-linear, non-homogeneous differential equations presented by Rosman; he replaced the header beams with a continuous less stiff medium. I checked my old box of dustcatchers and have long since filed the material...

You may be able to model the system with a finite element program using a 'softer' layer representing the headers...

I seem to recall that the effect was to yield a moment diagram that was similar to a propped cantilever... wl^2/8 and not wl^2/2

Few years back, ACI Concrete International magazine published an article with Basic computer program to do couples shear walls. I will try to see if I can find the year and month that this article was published.

Good luck
