<p align="justify">Structure's irregularity due to architectural design requirements become a major challenge to civil engineering science today. The height of seismic potential demands a safe and reliable building as a necessity. The availability of increasing narrow land makes high buildings as an alternative in the current development. <br /> <br /> <br /> In the building structure analysis against earthquake load is usually used infinitely (rigid) assumption so that the load distribution received by each column is proportional with the building stiffness and distance to the center of mass. Those approach is considered to be compliant but on the structure with long diaphragms it is necessary to be reviewed. <br /> <br /> <br /> Evaluate and compare floor diaphragm with rigid and semi rigid assumptions related to irregularity of diaphragm discontinuities. The building geometry is assumed to be the same for each model so that the correlation between 8 models can be compared. The building model used in this thesis is a concrete building with 10 floors. <br /> <br /> <br /> This research uses two methods, static equivalent and response spectrum analysis. The study results identified the semi rigid plates modeling on structures with long diaphragms and discontinuities with open areas having large displacement more than 50%. The initial assumption in which long diaphragm is assumed to be rigid in modeling is not recommended. <br /> <p align="justify"> <br />
