Abstract
Computer modeling aims at transforming the design process of buildings
worldwide from the use of 2D to 3D, 4D and 5D design and coordination
technologies. To investigate realistic values of bending moment and normal
forces, a full three-dimension (3D) analysis is needed in order to obtain correct
values, therefore the state of stress within a floor is more complex, in addition
to the normal stresses due to bending which is huge and in most cases must be
considered if failure is to be avoided. The purpose of this research is to study
and compare the effect of bending moment on floors of modeled high rise
buildings on elastic ground and firm ground. The research design was
exploratory which made use of Complex Program Lira to design and calculate
18-storey residential buildings. The results indicate that for both models the
maximum bending stress occurred at the first floors whiles the minimum
bending stress occurred at the top floors. The bending stresses from second
floor to the top floor are the same for each model. The model with elastic base
foundation has high bending stress as compared to the model with firm base
foundation by 30% for first floors and 28% for the subsequent floors. It could
therefore be concluded that bending moment effect on the floors was greater in
the model with elastic base than the model with firm base.
