Analytical Study of Vertical Geometric Irregular Diagrid Structure and Comparison with Tubular Structure

Anju Krishna, Arathi S

The rapid growth of high rise buildings leads to the evolution of new structural concepts. Structural systems nowadays are becoming stiffer and lighter. It is very important that the selected structural system is such that the structural elements are utilized effectively while satisfying design requirements. Recently diagrid structural system is adopted in tall buildings due to its structural efficiency and flexibility in architectural planning. Structural design of high rise buildings is governed by lateral loads due to wind or earthquake. Lateral load resistance of structure is provided by interior structural system or exterior structural system. Compared to closely spaced vertical columns in framed tube, diagrid structure consists of inclined columns on the exterior surface of building. Due to inclined columns, lateral loads are resisted by axial action of the diagonal compared to bending of vertical columns in framed tube structure. In most of situations, buildings become vertically irregular at the planning stage itself due to some architectural and functional reasons. A large number of vertical irregular buildings exist in modern urban infrastructures, and so the area of vertically irregular type of building is now having a lot of interest. This paper presents analysis of diagrid structure and tubular structure of irregular vertical geometry using ETABS software. Comparison of analysis results in terms of storey displacement and inter-storey drift under wind loading is presented in this paper.
