Structural Modeling of a High-rise Multipurpose Building

Abstract

Constructing a commercial cum Official plus Hotel building requires careful thought and planning. This design can be challenging to retail developers because of space constraints and the tendency of shoppers to prefer horizontal, rather than vertical. However, the massive land values of dense urban centers and high levels of traffic sometimes make vertical designs. A commercial building consumes more energy than any residential one. Designers now build systems to integrate artificial and natural light, air-conditioning units, acoustics and natural resources to make the commercial building more efficient. The technical classification of a commercial building for zoning purposes is that it has more than half of its floor space used for commercial activities. Such buildings are owned by various individuals and group entities who construct them or build them for profit. Developers build commercial cum residential properties with the intent to resell for profit or to lease for income. Other investors enter after construction for similar investment purposes. Over the history of building structures, the changes in technology have been tremendous. Part of this comes from the daily strategies of human living. In recent years, the trend is the construction of mixed-uses structures as limited natural resources, the expenses, time and stresses of commuting draw people back into the city center. As a result, urban centers include now mostly structures with a storefront next to the street, offices in the stories immediately above, and, finally in the upper levels, apartments for city dwellers. But these types of buildings are difficult to arrange to take total advantage of structural and mechanical systems. The living quarters, with their more intimate spaces, need closer column spacing, and have fewer vents and wires required meeting needs of comfort. Shallow floor-to-floor heights in the apartment areas are possible since they can be accommodated by a flat plate/flat slab design. Offices need grid or pan systems covered by drop ceilings to allow HVAC and electrical systems to be delivered to desired locations within each square. Hence, according to the need of rentable spaces, owner desires, aesthetics, cost, safety and comfort, architects and engineers are now facing the challenges of structural design to accommodate people's total daily life in one single structure. As outcomes, multiplan and multifunctional structures are now being constructed with different types of concrete floor systems considering lateral loads impacts which is a major concern to the designers and this study reflects this scenario.
