Abstract:

The diagrid is a framework of diagonally intersecting members that is used in the construction of buildings and roofs. It requires lower percentage of steel than a standard design. The need for columns and can be obviated by the use of diagrids. Diagonal members in the system carry gravity loads as well as lateral forces. Due to the triangulated configuration of members, internal axial forces arise in the members, in turn minimizing shear racking effects. Diagrid structures are generally used in the construction of high rise buildings as lateral forces get minimised. The primary goal of the research is the design and analysis of diagrid structural systems for the high rise buildings. The modeling was done by using PATRAN software and was analyzed using NASTRAN software. The study includes analysis of the representative models of various geometric forms for optimal construction in terms of strength. The investigations also include the study of the optimal cross-section of diagrid members. Quasi-static environment and Geometric nonlinear analysis is considered in the analysis of diagrid structures.
