Abstract

In normal cases, the columns that transfer the loads from the different building floors to the ground are vertical, but due to the increase in high rise buildings, especially multi-purpose buildings, it became necessary to make a transfer floor(s) to change the column system since it is logic to have same column in both residential and underneath commercial floors. Here the importance of the transformational roles floors with its various systems.

In this research, a comparison has been made between two major different systems of transfer floors roles, namely the slab system and the beams system, and then a 30 cms thickness slab was integrated with beams once on the crown of the beams another one was in the bottom of the beams. A commercial program has been used, which is the Etabs program version 19, (in order to approximate the reality because Etabs is one of the most programs which are used to design in reality). A three-dimensional model of the building with a transfer floor was made using ETABS program, a comparison was made between the four systems in the transfer floor, using the flexible response spectrum method. The impact of the transfer floor on the building’s drift, building’s displacement and the various obtaining actions were studied. The results show that using slab system is waste for money and the location of the slab in relative to beams has no effect.
