RC Shear Wall Behavior 1

[glove21]

I am currently in the process of trying to design a RC shear wall for a multistory building. I am looking into how the different sections of the shear wall interact. For instance if you have a two foot section above a doorway that connects to walls, how do those interact when they are stacked up through the building. I am not sure if that makes sense, but if anybody has some input I would greatly appreciate it.

Another question I had is if anybody knows the best way to go about an initial 'approximate' design for the wall to find size, shape, etc. before using a finite element analysis program like SAP to model this initial structure.

Thanks in advance.

1st Question: I believe you are referring to coupled shear walls. If the coupling beam is designed and detailed correctly, the system exhibits excellent performance. If not, it will sustain substantial damage. In the U.S., requirements for coupling beams are given in ACI 318 Section 21.7.7.

2nd Question: A good preliminary method for determining the amount of shear wall you need (also in the U.S.) is to provide walls such that the reliability/redundancy factor is about 1.0.

In ACI 318 21.7.7 spells out that the design procedure applicable for special RC walls/coupling beams (if they are part of earth quake resisting system).

Are all these procedures applicable for RC walls/beams if they are part of wind force resisting system ?

Thanks in advance
