INVESTIGATING THE EFFECT OF ARCHITECTURAL FORM ON THE STRUCTURAL RESPONSE OF LATERAL LOADS ON DIAGRID STRUCTURES IN TALL BUILDINGS

The inconsistencies between structure and architectural form of buildings are a usual cause of construction problems and added extra costs to construction projects, and designers are often interested in understanding the effects of the architectural form of a building on its structural responses. In this research, by means of the parametric modeling strategy, the interrelationships between the architectural form and the structural response of approximate 60 story tall buildings with diagonal grid (DiaGrid) structures are investigated. Various geometries and dimensions of the lower and top floor plans and the method of form generation which determine the ascending development of the building from base to top resulted in 49 architectural schematic forms. The Diagonal Grid (DiaGrid) members of identical steel tubular section as the structure of the tall buildings are later mapped on the generated architectural forms. Lateral loads, representing the equivalent static actions, are then applied to the structure and a static linear analysis is made. Eventually,results illuminate the structural behavior of initial models mostly depend on the base floor plan rather than other parameters and the architectural models in which the base floor plan has more side count approximately has better structural efficiency. This research can help architects in form generation phase in order that tall building experience better response to lateral loads and economically feasible structure are attained.
