3.5.2 Design Controls
The monolithic performance of the diaphragms and the new shear walls neces-
sitates the adequacy of both structural elements and the connection system
between the two building parts. For this purpose, the controls as follows should
be considered:
l RC shear walls
– Flexural design
– Shear design
l Diaphragms
– In-plane shear in diaphragms
– Connection of diaphragms
