Then optimal parameter values of Weibull distribution and the extreme values of thermal loading parameters corresponding to 100 years lifetime are estimated as shown in Table 1.The average temperature for the concrete slab bridge is proposed as the variation from -10掳C to 36掳C. This value is...
ABSTRACT A theoretical closed-form nine-slab thick-plate model for analyzing the thermal warping effects in concrete pavements is developed in this paper. It provides the thermal stresses and deformations of a system of nine jointed rectangular slabs resting on a Winkler foundation. It can be used...
The measurements were taken at several different locations for various concrete slab thicknesses. The effects of the pavement surface conditions, such as reflectivity, shading, and covering on the concrete temperatures were evaluated. The results showed that the significant differences in the maximum ...
Construction Issues and Design Procedure for Transverse Steel in Continuously Reinforced Concrete Pavement (CRCP) Test results show that 1) temperature variations exist along the concrete slab depth, 2) very little stress in transverse steel, and 3) warping and ... Choi,Pangil,Won,... - 《Inter...
As for the fixed slab, free slab, and foundation beam, the thermal stress can be calculated using the method in Chapters 7 and 8.78 For the complex cases, the finite element method can be used for calculation. For concrete dams with longitudinal joints, artificial pipe cooling is needed ...

1.The article introduces the gist how to control the molding-in temperature of concrete and the surrounding temperature of base slab in the construction of the bridge foundation concrete of the main pylon in winter, and how to control the temperature gradient in the course of curing concrete, ...
There is a significant difference on the setting temperature gradient when concrete paving is conducted under different conditions. The strain distribution through the depth of portland cement concrete slab changes greatly after considering the setting temperature profile. Currently, the consideration on buil...
For example, solar radiation was omitted in Yan Li’s numerical research on the temperature cracking propagation of mass concrete [13], the internal thermal boundary conditions of concrete closed girders were equivalently simulated by air elements in Chen B’s research [14], the fluctuation of ...
8.2.6.2 Design summer conditions In the design of the system for summer conditions: • Check summer design outdoor temperature and humidity. • Use the summer design room air temperature and humidity. • Estimate maximum temperature increase in the room, taking into consideration the actual he...
