Comparison Study for the Thermal Response of Concrete Slabs in UAE and ETABS According to CEB-FIP90 and ACI 224.3R

Abstract

This paper analyses the field test results for three concrete slabs poured in UAE to define the thermal response within the test period including the hourly environment temperature fluctuations and correlated lateral thermal deformations. Time-dependent properties (TDP) and non-time dependent properties (NTDP) ETABS finite element models are generated for all tested slabs according to CEB-FIP90 and ACI 224.3R codes respectively. The results of these ETABS models are compared with the actual thermal response of the tested slabs to determine the ideal method of both codes for predicting the thermal responses of concrete buildings in the UAE. The results of these field tests confirm that the displacements of TDP ETABS models are close to the test results with a 0.05 mm difference for the large slab.
