HiThis quarry is with reference to Clause 8.1.3.3.3
Suppose a single tower is having two wings separated by stairwell and elevator banks without having a connecting beam in between .There is also a level difference in diaphragm between the wings and central connecting portion .

What will be the correct philosophy with reference to above clause? should we consider two towers joined by a podium ?.

IN A STOREY shear walls contribute to storey stiffness. Lift well, stair well, if constructed of RCC walls, escalator wells should be considered as shear walls. Shear walls are of course connected to the main frame works by floor beams and even the floor slab also acts as diaphragm to the shear wall. Shear wall should be considered as equivalent to braced bay in a steel building. I have analysed some buildings manually to observe distribution of storey shear between columns and have found much of the shear is absorbed by shear walls.

Thanks

Gautam Chatterjee

dear Mr Gautam It is wonderful to note that you did analysis manually yes most of shear is absorbed by shear walls i did my post graduation from IIT Deldi and than i was approved for structures from Dubai municipality but gradually found more money in property trading but i really miss structural work Thanks and RegardsSandeepB Tech (Civil) NIT Surahkhal Managalore 1984M Tech (STR) IIT New Delhi00971 055 4522809From: "gautam chattopadhyay" <forum@sefindia.org>Sent: Mon, 19 Mar 2018 12:58:23To: econf@sefindia.orgSubject: [E-CONF] E- Conference on Tall Building QuerryIN A STOREY shear walls contribute to storey stiffness.
