Temperature Variation on Concrete Structures- A Case Study

Introduction

During steaming of wood log a complex stress and strain state appear in the RC basins. The effect of this state on the behavior of the basins is presented (Figure 1) [1]. The basin structure elements were designed by taking into account the classical analysis which is characterized by next actions: permanent loads, the temperature action due to the difference between interior of basins (80-90°C) and the outdoors temperature (20°C), the earth pressure and wood log pressure. The different temperature action between the RC basin walls and the RC foundation was not taken into account (Figure 1).

The Deformations due to Temperature Variation

It was calculated function of temperature on basin walls by using of well know procedure [2].

The temperature on the basin walls

Stress state from differential strain

The stress state due to different temperature of interior and outdoor of the wall is illustrated in Figure 3 (Figure 3).

Critical axial force of the wall

The critical axial force of a wall, according to Timoshenko- Gere, is calculated and compared with the effort from differential deformation between the wall and the foundation [3] (Figure 5).
