Stability study of high rise IBS building using STAAD PRO

Abstract

Stability presents a fundamental problem in solid mechanics which must be mastered to ensure the safety of structures against collapse. The theory of stability is crucial importance for structural engineering. Thus this study presents the behavior and stability of high rise building of Industrialised Building System (IBS). STAAD PRO software has been used to analyze the output of the results. Two different heights of building with 40.0 m and 150.0 m building are compared in term of bending moment, shear forces and different value of wind speed. The structural evaluation shows that bending moment at the lower floor of building are greater than the bending moment at the top floor. Besides, analysis had shown shear forces have slightly difference in every floor. This is due to each floor carry an equal live load and dead load to resist shearing forces. The increases of wind speed increase the value of bending moment of structure. Furthermore, the intensities of wind increase with height of the building. Shortly this study prove that lower building is more stable than the higher building because the structure has to carry more vertical loads and the lateral wind. However study has to be improved by increasing the column sizes progressively towards the base of the floor to resist lateral loads to increase the stability of building.
