EFFECT OF ARCHITECTURAL DESIGN IN TWISTED FORM BUILDINGS TO STRUCTURAL SYSTEM DESIGN

Abstract

Architects and engineers are looking for different solutions in their designs and the number of buildings with twisted forms is increasing each day with the development of analysis and drawing methods, the development of material technology, the increase and optimization of construction techniques, the. As the height of the building increase, the forms obtained by the rotation of each floor slab relative to the previous slab can be defined as twisted forms. It is possible to construct many different twisted building forms by using different rules, templates, and parameters while designing. Twisted buildings, which can be accepted as a new design methodology with respect to traditional methods, provide many advantages in design but also give rise to significant and critical problems. In this study, the geometrical features and parameters of twisted buildings are introduced. Architectural features, advantages, and disadvantages of twisted buildings are discussed. The positive and negative effects of the twisted form on the behavior of the structural system are investigated, and types of structural systems are provided as an example for buildings with this form. Case study twisted buildings, the problems encountered during the design and construction of these buildings, and the solutions proposed and applied by the designers to these problems are studied. Consequently, the advantages, disadvantages, applicability, and sustainability of twisted form building are evaluated within the framework of the rules and guidelines in today's regulations, and the issues that should be considered in the design of the building and during the construction are discussed.
