Ascendancy of connecting assymmetrical r.c. towers using sky bridges in improving the dynamic response
Abstract: Structures constructed to serve similar purposes adjacently, are often connected to each other. These connections may be sometimes in the form of sky-bridges. Connecting the structures with each other does not cause any modification in the behaviour of the structures in the static condition, but such modification may cause huge effects on the structural behaviour under dynamically activated condition. This article basically deals with study of connected structures, when connected …
