It was observed that lateral displacement reduced by 50% to 56% by use of X-type bracing .Base shear of the building was also found to increase by use of X-type bracing, indicating increase in stiffness. Also, another reason for the braced frame system to be efficient is, it makes the structure laterally stiff. Results are conveyed in form of tables, bar charts. Anuj Chandiwala, "Earthquake Analysis of Building [6] This book employs exaggerated deformation shapes to emphasise deformations, and thereby, to develop the most needed intuition of structural behaviour of buildings during earthquakes and its consequences on earthquake-resistant design. Earthquake plays an influential role in analysis and designing of structures. Wind speed of 55 m/s and earthquake zone 5 is adopted for analysis.
