Abstract: The Analysis of the tall building is carried out to find the optimum position of outrigger system and belt truss by using lateral loads. The three dimensional model is considered and designed for the gravity load and placing of first and second position of the outrigger. Considering the design of Wind load is calculated by using IS 875 (Part 3) and Design of Earthquake load is calculated by using code IS 1893(part-1): 2000 in order to achieve reduction in drift, Deflection and story shear. The analysis is done by considering tall vertical irregularity of 30th storey of 7 X 7 bay for 1 to 10th storey and 7X6 bay 11th to 20th storey and 7X5 Bay 21st to 30th storey.
