The stiffening effect of non-structural elements in a building has been recognized for many years, but it has generally been neglected in design procedures due to lack of understanding of the interaction between these elements and the building’s primary structure. Cladding items are usually unaccounted for in contributing to the lateral stiffness of a building structure. The non-structural items, which are neglected, will contribute to a lesser degree in controlling the drift, especially in tall buildings. The paper presents the interaction of the primary moment resisting frame with grid panel cladding system.

 
 

Ancient tall structures such as the pyramids of Giza in Egypt, Mayan temples Tikal, Guatemala, and Qutab Minar in India are just a few examples testifying to the human aspiration to build increasingly tall structures. These buildings are primarily solid structures serving as monuments rather than space enclosures. By contrast, contemporary tall structures are human habitats, conceived in response to rapid urbanization and population growth, although the sheer audacity in their critical scale may often give the dubious title of monumental structures to these space enclosures, which in itself has not changed the basic stability and strength requirements: the structural issues are still the same, though the materials and methods are different.

A high-rise is a tall building or structure. Buildings between 23 m and 150 m (75 feet and 491 feet) high are considered high-rises. Buildings taller than 150 m (492 feet) are classified as skyscrapers. High-rise structures have certain features. The structures are high and lead to higher vertical loads and higher lateral loads (mainly due to wind stress) in comparison with lower buildings. The materials used for the structural system of high-rise buildings are reinforced concrete and steel. Most skyscrapers have a steel frame, while residential tower blocks are usually constructed out of concrete.
