Basically, this design approach is based upon the main idea that structures suffer Degradation over time, thus reducing its initial safety ranges
ConceptsThe Idea of Life-Cycle Design
Degradation Over Time
![Page 7: Life cycle design](https://reader035.fdocuments.us/reader035/viewer/2022062320/55d7719cbb61eb1a258b4582/html5/thumbnails/7.jpg)
For Life-Cycle Design we have to consider thefollowings:
- Structure Degradation
- Resistance Alterations
- Safety Reduction

• Fatigue• Cracking• Corrosion• Cycling Loads• Temperature
Resistance Alterations are Induced by:

Economical Aspects
![Page 13: Life cycle design](https://reader035.fdocuments.us/reader035/viewer/2022062320/55d7719cbb61eb1a258b4582/html5/thumbnails/13.jpg)
Need of vast and accurate Data, like the Mechanical Loads and Natural Hazards
Methods for Surveying structural damage during its life-time
Development of advance Construction Methods
More complex Design Procedures
Difficulties

More Efficient Structures
Flexibility in Economical Aspects for a Structure
Ability to Warranty Structures
More Durable and Reliable Structures
Advantages
