Tall Building Case Study

As the height of buildings increase the design of its structural system becomes increasingly specialized and complex, therefore, The council on tall buildings defines a high rise, from structural design point of view, as follow: a tall building is not defined by its height or number of stories, but by the different condition its height creates in the design, construction and operation from those exist in common of certain region and period. This requires doing studies to determine the effect of load action on tall buildings to ensure that structure efficiency is achieved. The same basic principles and function of structural design apply to tall buildings as for any other common building is to carry effectively and safely all the …show more content…

• It must collaborate with and facilitate service systems, such as heating, ventilating, air conditioning, horizontal and vertical transport, and other electrical and mechanical systems.
• It should facilitate constructing of the building, resisting fire, absorb noise and it should be economical. Factors affecting choice of structural system: The design of tall buildings not only includes the structure, but also the building envelope, services and finishes. All these elements must be coordinated together by using components modular to ensure maximum repetition and standardization in the predetermined grid layout. The choice of structural grid defines column positions and the main beams spanning between them and is a very important design decision, the following points should be considered:
• a column should normally be positioned at every intersection of two grid lines
• a main beam should normally be positioned along every grid line
• ideally grid lines should be orthogonal (the two sets of parallel lines forming a rectangular grid), and the spacing between grid lines should be regular (for circular buildings radial and circumferential grids are often
