This presentation discusses the effects of temperature and shrinkage on structural analysis, highlighting that deformation can occur without external loads. It identifies causes of shrinkage, such as water evaporation and concrete drying, and explains the potential damages, including cracks and harmful stresses in structures. The presentation emphasizes careful material selection and analysis of environmental conditions during design to mitigate these effects.

1. WELCOME

PRESENTATION

2. PRESENTATION ON
TEMPERATURE & SHRINKAGE EFFECT ON
STRUCTURAL ANALYSIS

4. Introduction:
The deformation of structure can be
occurred by stresses caused by external
loads. But deformation & volume changes
can also occur without any external loading.
The most important of these are shrinkage
& temperature effect.

5. Structure mainly two types:
1.R.C.C Structure:
2. Steel Structure:

6. Reasons for shrinkage:
1.By evaporation of water.
2.Drying of concrete.
3.Increasing of temperature

7. Temperature & Shrinkage effect:
1.It may cause deleterious crack as in
slabs,walls etc.
2.In structure that are statically
indeterminate & most concrete structure, it
may cause large & harmful stresses.
3.It may cause deformation of total
structure.
4.It may affect to the fixed joint.

8. Cracks due to temperature &
shrinkage effect:

10. Crack in wall:

12. Shrinkage in an unrestrained reinforced
concrete member :

13. Shrinkage in a restrained reinforced
concrete member :

14. Due to accident massive change in
temperature of the structure causes
the fall of twin tower:

15. Matter of concern during
design:
1. Careful during selection of material
2.By analysing previous weather report.
3.By analysing previous max temperature record.
4. By predicting the future condition.
5.The coefficient of thermal expansion &
contraction should be within the allowable range.
6.By increasing aggregate content.
7.By adjusting water content.
8.Careful curing is needed.
