High Rise Structure

The structural system of a high-rise building is designed to cope with vertical gravity loads as well as lateral loads caused by wind or seismic activity. The structural system consists only of the members designed to carry the loads, and all other members are referred to as non-structural. The determination of the structural system for a high-rise building involves the selection and arrangement of the major structural elements to resist most efficiently the various combinations of gravity and lateral loading.
A high-rise building needs to be stabilized for horizontal load and to achieve this, several different structural systems can be chosen. All of the different systems have evolved from the traditional rigidly jointed structural frame. The fundamental design for all these structural systems has been to place as much of the load-carrying material as possible around the building’s external fringe to maximize its flexural rigidity.
