In recent days due to lake of availability of land the construction of tall buildings widely
increasing, these buildings are affected by lateral loads due to wind and earthquake. There are many types
of lateral load resisting structural systems for tall building such as rigid frame, shear wall, wall-frame,
braced frame, dia-grid structure, tube system, outrigger, and core structure. Dia-grid structural system
have emerged as one of the most innovative and adoptable approaches to structuring buildings in recent
time. Dia-grid structural system is adopted for high-rise building because of its structural efficiency and
flexibility for planning. Dia-grid stability systems hold great potential for future that wish to merge
architecture and engineering in a compelling way as their execution. Dia-grid is structural system which
resists the lateral forces by axial action of diagonal provided in periphery. The lateral displacement in X
and Y direction for dia-grid structure is significantly less as compared to conventional structure, Hence the
overall displacement of the structure can be effectively controlled by adopting dia-grid structure. Dia-grid
structural system do not required any interior core to resist the lateral load because lateral load is resisted
by the peripheral diagonal columns. Dia-grid structural system has emerged as a better solution for lateral
load resisting system in terms of lateral displacements, steel weight, and stiffness. This paper represent the
development and research work done on the seismic analysis, methodology of preliminary design,
efficiency and effectiveness of dia-grid structural system.
