he structure is the backbone of building. Construction of the multi‐storey building is quickly increasing throughout the globe. Advances in construction technology, materials, structural systems, and analysis and design software package expedited the expansion of those buildings. Diagrid buildings square measure rising as structurally economical furthermore as architecturally important assemblies for tall buildings. The diagrid structural system may be outlined as a diagonal member shaped as a framework created by the intersection of various materials like metals, concrete or wood beams that are used in the construction of buildings and roofs. Diagrid structures of the steel members are efficient in providing a solution both in term of strength and stiffness. In my thesis work study the safety and minimum harm level of a structure may well be the prime demand of high-rise buildings. In this thesis Analysis and design of 16 storey diagrid building with plan of 18 m × 18 m size is considered. Key Words: Diagrid building, STAAD-Pro, Storey Drift, Storey Shear
