“…With the development of computer programs, numerical simulation and experimental programs have been proposed to extend the way of obtaining data that implements the most critical environmental conditions. More studies are conducted on the precast, prestressed concrete bridges [11][12][13], and GFRP bridge decks under the design temperature gradient [14]. The temperature distribution of a 1:3.5 scale model of the Long Key Bridge was measured and compared with the analytical predictions.…”

The internal temperature of cast-in-place concrete bridges undergoes strong variations during the construction as a result of environmental factors. In order to determine precisely such variations, the present study relies on the finite element method, used to model the bridge box girder section and simulate the internal temperature distribution during construction. The numerical results display good agreement with measured temperature values. It is shown that when the external temperature is higher, and the internal and external temperature difference is relatively small, the deviation of the fitting line from existing specifications (Chinese specification, American specification, New Zealand specification) is relatively large and vice versa.

“…The temperature stress or the temperature internal force is related to the value of the temperature difference. And the temperature difference contains three categories: the temperature difference between inside and outside caused by hydration heat of concrete [1], gradient caused by sunlight or cold [2,3], and seasonal overall temperature difference of structure [4]. In harbor engineering, there is more research on concrete cracks resulted from the hydration heat temperature difference or gradient caused by sunlight [5][6][7].…”

When the wharf structure is completed, the temperature is different with the one at the usage period. The temperature difference will lead to the temperature strain, and create the lateral deformation and internal forces of the piles. Based on the assumption of the free temperature difference of beam-slab-system, the spatial simplified calculation model of the foundation pile and the stiff platform about the temperature stress in all-vertical-piled wharf is first proposed, the related calculation method is also given. The numerical example shows that the accuracy of this simplified method could meet the demand of preliminary design. In order to reduce the pile-top internal forces, the foundation piles should be arranged symmetrically. The pile-top internal forces are in direct proportion to the forth power of the pile diameter, with the increase of the pile diameter in all-vertical-piled wharf, the analysis of the temperature stress must be taken seriously.
