Abstract: In this paper, there will be an analysis study to figure out the impact of the environment thermal loads, shrinkage and creep at multi-storeies reinforced concrete frame buildings in the Arabic area. Etabs models will be prepared based on NTDP and TDP of ordinary concrete, considering two columns heights as 3m and 6m, and two supports conditions as fixed and hinged to define the major aspects affect the thermal response of multi-storey concrete frame buildings concentrating at the thermal deformations and the columns reactions, then it will be compared with the thermal response of existing concrete building considering both methodologies of TDP as per CEBFIP99 and NTDP as per ACI Committee to define the optimum methodology to be recommended and followed The generated Etabs models confirmed that the time dependent properties method is the optimum with a clear conversion between time dependent properties model and the existing parking thermal deformations. increasing the thermal reaction forces at column supports reduces the correlated thermal displacements due to stiffness increment of the entire building, The first-level displacements of multi-storey buildings are slightly smaller than those of upper levels and single-storey buildings, but the displacements of the second level are slightly larger than those of the other levels. Meanwhile, the displacements of levels above the second storey are close to the displacements of single-storey models. Overall, there are small differences between multi- and single-storey models,. finally, the importance of analyzing thermal loads fluctuation at columns reactions for multi storeies buildings whereas the reactions of multi storeies cannot be predicted from single storey analysis.
